Preface to the Sixth Edition 

The year 2005 marks the 10-year anniversary of the publication of the Medicine Blue Book. I wrote the draft duringmy intemship and completed the book my first year of residency at Manila Doctors Hospital. Even then, my utmostdesire in sharing this book is to assist the many struggling doctors and nursesin our different training institutions. Ihad seen how hard and how unrewarding. medical training can be. I hope the Blue Book can be your friend andcompanion at some point in your career.

 One of the biggest problems afflicting our country right now is the high cost of healthcare. To address this, the

Blue Book contains several unique features: 1) effective drug options are listed whenever possible and noted with asmile =) icon, (2) priority laboratory exams to request are highlighted in bold, (3) the treatment regimens aregenerally listed according to importance, which means that crucial treatment strategies are listed first and supportivetreatments are listed last, (4) the dosages of drugs have been adjusted for the average Asian patient, and (5) onlytests and drugs available in our local setting are included.

 This edition presents major revisions and updates in all chapters. The latest (local ones if available) have been

utilized. Again, myprofuse thanks to, Clemente Amante, Dr. Virgilio Banez, Dr. Carlos Chua, Dr. KennethHartigan-Go, Dr. Ruby Go, Dr. Cecilia Montalban, Dr. Elizabeth Montemayor and Camilo Roa Jr. for their selflessand untiring efforts in updating the text.

 I am also greatly indebted to several people in my medical education: Dr. P. Ariniego, Medical Director at De La

Salle University Medical Center; , Dr. Nelson S. Abelardo, past Chair of the Department of Internal Medicine at

TheManila Doctors Hospital; and Dr. Rody G. Sy, former Head of the Section of Cardiology at UP-Philippine GeneralHospital. 

Finally, I would like to thank my parents, Mr. Ong Yong and Mrs. Juanita Tan Ong, for their wholehearted supportin this endeavour. And to my wife, Anna for all her hard work in publishing this book. Above all, I humbly thank theLord God for His guidance and inspiration. I can accomplish nothing without Him but "I can do everything in Christwho strengthens me." Thank you for reading and may God bless us always.

 I am Dr. Neo. Aside from being trained with the knowledge and skills of western

medicine, I also have proclivities in unconventional software applications which lead me

to this work, the 6 th Edition of the Medicine Blue Book. The medicine Blue book has

been integral in our line of work. From med school, internship, moonlighting, crossconsultation beyond our specialties to treating our neighbours knocking at our doors

late at night with tummy cramps. 

We doctors live underpaid and overworked conditions. With the MD to nursing phenomena, the medical diasporas, the mistrust of patients, threat from the government

and media of malpractice bills who know nothing of our line of work and passions. Weare one of the unsung heroes of our nation. As part of this brotherhood in white, with

blood and tears trailing our footsteps, this work is my tribute.

 To my mentors, seniors, subordinates, your ultimate sacrifices did not go unnoticed. Tothe original authors of the book, I deeply apologize for lifting your whole work to be

shared to the medical force in their PDA, which is handier nowadays than bringingdifferent books and references. I hope you could consider it as my ultimate complement

and a gesturing of honouring you for choosing your work to be selflessly shared to ourother brothers and sisters-in-arms braving their training and practice without gain exceptfor the satisfaction that we have helped them. I hope you could also forgive my humility

which would seem to be cowardice represented by my anonymity.

 Mabuhay tayong lahat.

ADVANCED CARDIAC LIFE SUPPORTTo Cardiology Page

To Main Table of ContentsTo Detailed Table of Contents

 Basic Principle: To sustain life, (1) blood must circulate and (2) blood must be oxygenated optimally.

General Guidelines: Take command. Obtain brief history.Identify and treat reversible cause:

5H’s: Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hyperkalemia or hypokalemia (othermetabolic problems), Hypothermia.5T’s: Tablets (drug overdose, accidents), Tamponade cardiac, Tension

pneumothorax, Thrombosis coronary (MI, Thrombosis pulmonary (embolism). 

Step 1: Circulation.

 Auscultate the precordial area for a heartbeat while palpating for the carotid pulse.If negative, start CPR.Note: Place bedboard. Do effective 4-5 cms sternal compressions.

 Step 2: Oxygenate Optimally.

Is the patient cyanotic? Is the patient still breathing?If negative, check airway and do ambu bagging with 'tight' face mask.Note: Give 100% oxygen. Make sure ambu bag tube is connected to the oxygen tank. Suctionsecretions as needed. Hyperventilate initially.

 Step 3: Treat the Cardiac Rhythm. Assess by cardiac monitor.

Done simultaneously:l. Insert IV line.2. Intubate patient if necessary (for asystole, electromechanical dissociation, bradyarrhythmia, orpersistently unstable rhythms).3. Get ABG's if with pulse (treat hypoxemia and acidosis).

 I. Rhythm: Asystole (Silent Heart)

1. Continue CPR. Obtain IV access.

2. Epinephrine (1 mg/ampnle) 1-2 ampules IV stat q 3-5 minntes continuously until there isa cardiac rhythm or until CPR is stopped. May give epinephrine 1 mg ampule in 10 ml NSS

via ET tube q 3-5 minutes if no IV line is inserted yet.3. If unable to rule out fine ventricular fibrillation, defibrillate with 360 Joules.4. Atropine 1 mg IV; repeat q 3-5 min. Maximum of 3 mg.5. Consider external or transvenous pacing.6. Consider Bicarbonate 1 amp (1 meq/kg) if more than 15 minutes have elapsed since the hearthas stopped. 

II. Rhythm: Ventricular Fibrillation or Pulse less Ventricular Tachycardia

l. Defibrillate with UNsynchronized 200 Joules stat, repeat with 300 Joules if unsuccessful, then

360 Joules.2. Continue CPR between defibrillations or until a defibrillator is available.3. If no conversion, give epineprhine 1 ampule prior to next defibrillation for cases of resistant or

fine ventricular fibrillation. Repeat q 3-5 minutes as needed.4. Continue Defibrillation until rhythm is converted to sinus.

5. Consider anti-arrhythmic drugs:a. Amiodarone 150-300 mg (1-2 ampules) slow IV in 10 minutes for resistant ventricular

fibrillation or ventricular tachycardia. Repeat dose if necessary.or b. Lidocaine 50-100 mg (1 mg/kg) IV and then start drip at 2 mg/min. May repeat bolus 40 mg

(0.5 mg/kg) IV ofter 5 minutes. Maximum of 200 mg (3 mg/kg). If necessary, increase drip rate by1 mg/min to maximum of 4 mg/min. May give Lidocaine via ET tube plus 10 ml NSS.

Page 25: Medicine Blue Book

8/9/2019 Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 25/266

6. For polymorphic ventricular tachycardia (torsade de pointes), give Magnesium Sulfate 1-2 gm IVdiluted in 100 ml DSW and given in 2 minutes.7. Consider Sodium Bicarbonate 1 amp slow IV. 

III. Rhythm: Unstable Ventricular Tachycardia with Pulse

For presence of chest pain, dyspnea, MI, heart failure, or systolic BP < 90 mmHg:1. Cardiovert with synchronized 100, 200, 300 Joules. If patient is awake give Midazolam 2-5 mg

IV for sedation. May omit precordial thump.2. Consider anti-arrhythmic:

a. Amiodarone 150-300 mg (1-2 ampules) slow IV in 10 minutes. Repeat dose i f necessary.

  or b. Lidocaine 50-100 mg (1 mg/kg) IV and then start drip at 2 mg/min. May repeat bolus 40

mg (0.5 mg/kg) IV after 5 minutes. Maximum of 200 mg.3. If no conversion, cardiovert at synchronized 360 J, or if recurrent ventricular tachycardia,

cardiovert again starting at previously successful energy level, then after conversion, continuemedications.

 IV. Rhythm: Stable Ventricular Tachycardia with Pulse

1. Precordial thump.2. Give anti-arrhythmic drugs:

a. Amiodarone 150 mg slow IV (1 ampule) in 10 minutes.or b. Lidocaine 50-100 mg (1 mg/kg) IV and then start drip at 2 mg/min. May repeat bolus 40 mg

(0.5 mg/kg) 1V every 5 minutes until VT resolves. Maximum of 200 mg.3. If drugs fail, cardiovert with synchronized 100, 200 Joules.4. Treat accordingly if cardiac rhythm degenerates. 

V. Rhythm: Bradycardia

 A. For chest pain, dyspnea, drowsiness, heart failure, or systolic BP < 90 mm Hg:1. Atropine 0.5-1 mg IV stat. Maximum of 3 mg (0.04 mg/kg). May give via ET tube with 10

ml NSS.2. Continue CPR support if HR < 40 bpm.3. Consider external or transvenous pacing.

4. Consider Dopamine drip or Epinephrine drip as a temporizing measureB. For type II second degree dh third degree AV block, consider external or transvenous 

pacing.C. If without symptoms, observe!

 VI. Rhythm: Electromechanical Dissociation (EMD)

Definition: Sinus rhythm by cardiac monitor but without palpable pulses. No BP.Etiology: EMD can be secondary to inadequate fluid volume, pericardial tamponade, tensionpneumothorax, hypoxemia or acidosis. Less correctible causes include massive MI, prolongedischemia during resuscitation and pulmonary embolus.

1. Continue CPR

2. Correct primary problem (see etiology).3.. Epineprhine 1 mg IV q 3-5 min

4. Consider Bicarbonate 1 amp (44 meq) slow IV.

 VI. Rhythm Successfully Converted to Sinus Rhythm:

1. If Systolic BP = 100 mm Hg:

Obtain laboratory exams: ABG, ECG (check for MI), CXRCBC, Na, K, RBS, Creatinine2 If Systolic BP =90 mm Hg:

i. Start Inotropics: Dopamine with or without Dobutamine.ii. Correct low volume, acidosis and hypoxemia.iii. Do ABG and other laboratory exams if feasible.

  Advice

Page 26: Medicine Blue Book

8/9/2019 Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 26/266

 a. Adequate airway, ventilation, oxygenation, chest compression and defibrillation are more

important than initiating IV line and injecting medications.b. IV medications should be given by bolus with few exceptions. After each IV medicine, give 20-30

ml bolus of IV fluid and elevate the extremity.c. Do most of your interventions in the first 10 minutes of the CPR. Otherwise, the chance of

reviving the patient decreases markedly.

d. Lastly, treat the patient, not the cardiac monitor.

(check for episodes of ventricular tachycardia) ECG, 2-D Echo with doppler 

 

Treatment Plan:1. Consider age of patient and the cardiac status. Most important considerations for admission andtreatment are the following:

a. Symptomatic patients with dyspnea, syncope, or dizzinessb. (+) Organic heart disease, especially post-myocardial infarctionc. low ejection &action of < 40%d. Lown's grading = 4a

2. Look for a possible secondary-etiology for PVC’s and treat this, e.g. CAD, thyroid diseases,acidosis, alkalosis, hypercaprea, hypoxia, hyperkalemia, hypokalemia, digitalis excess, mitral valve

prolapse, cardiomyopathy, or connective tissue disorders. 

Therapeutics:1. Decrease precipitating factor, e.g. control anxiety and avoid alcohol, digitalis, caffeine coffee,softdrinks or tea.2. Treat the underlying cause, e.g. give nitrates for CAD, correct electrolyte imbalance etc.

3. Supportive: Oxygen, sedatives4. Treatment for PVC’s or Ventricular Tachycardia after correcting other factors:

a. Beta-blockers - empiric and cheap treatment (esp. for patients with MVP)

b. Lidocaine IV bolus and drip for acute episodes only.

c. if resistant, consider Amiodarone IV or PO: Amiodarone preparation: 150 mg/3 ml vial

IV loading dose: 500-1000 mg per 24 hr IV loading doses (5-10 mg/kg bodyweight per 24 hr)Example orders: Give 150 mg slow IV push over 10-30 minutes (with BP and HRmonitoring) followed by D5W 250 ml + 150-300 mg IV Amiodarone to run for 24hours. Supplemental doses of 150 mg IV over 10-30 minutes may be given forrecurrent arrhythmias especially hg the early phases of dosing OR

 Oral Loading Dose: (10 mg/kg body weight per day for 2 weeks), Amiodarone 200

mg 1 tab PO TID for 2 weeks then maintenance of Amiodarone 200 mg 1 tab ODthereafter Amiodarone's side effects include hyperthyroidism, hypothyroidism, andinterstitial pulmonary fibrosis. Check thyroid function every 3-6 months

 5. For ventricular tachycardia or cardiac arrest due to ventricular fibrillation, ImplantableCardioverter/Defibrillators (ICD) are proven to be beneficial in preventing sudden cardiac death.However, ICD’s are very expensive. Consult a cardiologist-electrophysciologist.

adrenal hyporesponse secondary to long-term steroid use. 

B. CP clearance and need for intraoperative monitoring. Three basic questions:1. What is the medical status of the patient?

a. What is the functional capacity of the patient? Can the patient climb at leasttwo flights of stairs with ease?b. What is the patient's Goldman's Classification (Class I – IV)?

Note: Low-risk patients to clear leave good functional capacity and are Goldman’s Class L2. What is the operative procedure?

a. High-risk surgery: Emergency major operation, aortic and other majorperipheral vascular surgery, anticipated prolonged surgery with large bloodloss.b. Intermediate risk surgery: Carotid endarterectomy, head and neck,intraperitoneal and intrathoracic, orthopedic, prostate surgery.c. Low-risk surgery: Breast, cataract, endoscopy, superficial procedures.

3. What type of anesthesia is to be used?

From high-risk to low-risk: General anesthesia, spinal anesthesia, subarachnoidblock, regional anesthesia, local anesthesia. 

C. Based on the answers above, we can now estimate the operative risk involved. Low-risk

patients undergoing low-risk procedures have low operative risk. Conversely, high-risk patientsundergoing high-risk procedures have high operative risk and need intraoperative monitoring. Forother combinations of risk, the physician is advised to use his/her clinical judgment before clearingthe patient.

A. Screening:In patients without coronary heart disease (CHD), the National Cholesterol Education Program(2001) recommends screening with a complete lipid profile (total cholesterol, LDL cholesterol,HDL cholesterol, and triglyceride) after a 12 hours fast for all adults > 20 years of age once every5 years and as indicated.

 B. Positive Risk Factors (Add 1 point each):

 Age and gender (male > 45, female > 55 or premature menopause in women without estrogenreplacement), current cigarette smoker (ten or more cigarettes per day), hypertension, familyhistory of premature coronary artery disease (myocardial infarction or sudden cardiac deathbefore age 55 in a male first degree relative and before age 65 in a female first degree relative),and low HDL cholesterol < 40 mg/dl.

 C. Negative Risk Factor: Subtract by 1 point if HDL > 60 mg/dl

 D. Normal Values: Ideal Lipid Profile

- Total Cholesterol (TC) , 200mg/dl- HDL >=40 mg/dl- LDL <130mg/dl- Triglycerides (TG) <200mg/dl

1. Goal o f treatment: Set treatment goal for target LDL

2. Start with Non-Pharmacologic Treatment:a. Diet therapy: Moderation in diet; increase intake of fish and vegetables. Diet for 8weeks, then recheck Lipid Profile after 8 weeks. If repeat LDL values fall above the cut-offlevels for starting drug treatment, initiate treatment with Statins.b. Aggressive coronary heart 'disease risk reduction: Smoking cessation, hypertensioncontrol, Aspirin treatment for documented coronary disease.c. Weight reduction if obesed. Increase physical activity (e.g. brisk walking, swimming)e. Consider stopping beta-blockers and thiazide diureticsf. Correct hyperglycemia (if diabetic) and replace thyroid hormones (if hypothyroid)

INDICATIONS FOR PERMANENT PACEMAKER INSERTION 

To Cardiology PageTo Main Table of Contents

To Detailed Table of ContentsData

There is general agreement that a permanent pacemaker should be implanted in the following conditions(Class I Indications):

  A. Complete Heart Block with

l. (+) Symptoms due to the AV block (e.g. syncope, heart failure)2. Asystole = 3 seconds by Holter monitoring even if without symptoms3. HR < 40 bpm even without symptoms (any escape rhythm < 40 bpm)

B. 2nd Degree AV block, permanent or intermittent, with symptomatic bradycardia

C. Sinus node dysfunction with symptomatic bradycardia. In some patients this due to long-term

essential drug therapy for which there are no acceptable alternatives e.g. digoxin fortachycardia-bradycardia syndrome.D. Carotid sinus stimulation causing recurrent syncope or asystole > 3 seconds in the absence of anymedication that depresses the sinus node or AV conduction.

 

Additional Data: 

1. Patients should not be taking any drug that depresses the heart rate (i.e. digoxin, amiodarone,beta-blockers etc.). For example, digoxin needs 5 days to be completely excreted by the body, hence, wemay opt to temporize the patient for 5 days even if he/she fulfills the above criteria.2. The key  clue in most of the above indications is the presence of symptoms.3. Acute MI cases who develop bradyarryhthmias are usually treated with temporary internal pacing sincethe problem is reversible. Inferior wall MI is associated with edema of the AV node which usually resolvesin 1- 2 weeks.4. In poor patients who cannot afford permanent pacing, drug therapy with Bricanyl 2.5 mg tab BID-TIDmay be given with inconsistent results. In severe symptomatic cases, permanent pacing is the onlyalterative. The cheapest pacemaker available costs around Php 50,000.

CBC Urinalysis, Potassium, FBS, Creatinine, Calcium, Total Cholesterol, HDL, LDL, TriglyceridesECG IV. Approach to Treatment

 A. Rule out correctable and secondary causes of hypertension first.

Theseinclude drug-induced hypertension, thyroid or parathyroid disease, chronic disease,renovascular disease, coarctation of the aorta, primary aldosteronism, chronic steroidtherapy and Cushing’s syndrome, and pheochromocytoma.

B. Encourage Lifestyle Change for Essential Hypertension

1. Stop Smoking2. Lose weight if overweight. Maintain body mass index of 18.5 – 24.9 kg/m^2 for every10 kilogram of weight loss, BP drops by approximately 5-20 mm Hg.3. Reduce sodium intake (< 2 gm of sodium or approximately < 6 gm of sodium chloride).4. Healthy diet. Consume a diet rich in vegetables, fruits and low fat dairy products.

Reduce dietary saturated fat and cholesterol intake for overall cardiovascular health.Reducing fat intake also helps reduce calorie intake, which is important for control ofweight in type II diabetes5. Engage in regular aerobic exercise once BP is controlled. At least 30 minutes per day,most days of the week. Brisk walking is good exercise.6. Limit alcohol intake to less than 1 oz/day of ethanol (24 oz of beer, 8 oz of wine, or 2 ozof 80-proof whiskey)7. Maintain adequate dietary potassium, calcium and magnesium intake.

 C. Choice of Antihypertensive Drags Based on Patient Characteristics. (List includes

Page 51: Medicine Blue Book

8/9/2019 Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 51/266

compelling indications.)

 

1. Diabetic patients and those with chronic kidney disease: Use ace-inhibitors or

angiotensin II antagonists to delay diabetic nephropathy.2. Young patients:Use beta-blockers unless contraindicated.

3. Coronary artery disease patients: Use beta-blockers, calcium-antagonists. Avoid

hydralazine.4. Heart failure patients: Use ACE-inhibitors and/or diuretics. Generally avoid

beta-blockers and calcium-antagonists.5. Athletes: Avoid beta-blockers and diuretics.

6. Broncho-pulmonary disease patients: Use Verapamil and other calcium-antagonists.

 Avoid beta-blockers.7. Peripheral vascular disease patients: Use calcium-antagonist (nifedipine),

vasodilators, or ace-inhibitors. Avoid beta-blockers.8. Dyslipidemic patients:Avoid beta-blockers and diuretics.

9. End-stage renal disease patients: Use calcium-antagonists, diuretics and

centrally-acting agents. Caution on ace-inhibitors.10. For stroke patients:Use ACE-inhibitors and/or diuretics.

11. Elderly patients: Use diuretics. Generally use lower dosages. Be wary of

pseudohypertension wherein the elevated BP is due to brachial artery atherosclerosis andnot hypertension per se. 

D. Treatment Goal and Guide:

1. For hypertensive patients with diabetes or renal disease, the target BP is < 130/80 mm Hg. Forother patients without cardiovascular risk factors, the BP goal is < 140/90 mm Hg.2. JNC VII recommends the use of thiazide-type diuretics as first line treatment unlesswith contraindications. Two diuretics locally available are Aldazide given at 1/2 tablet a day andNatrilix. The most commonly used thiazide-type diuretic hydrochlorothiazide may soon beavailable.

To Main Table of ContentsTo Detailed Table of Contents

 

Data:

  A. Definition: Asthma is a chronic inflammatory disorder of the airways in which many cells play a roleincluding mast cells, eosinophilia, T-lymphocytes and neutrophils In susceptible individuals, thisinflammation causes symptoms which are usually associated with widespread but variable airflowobstruction that is own reversible either spontaneously or with treatment, and causes an associatedincrease in airway responsiveness to a variety of stimuli. 

B. New Classification of Asthma According to Severity:

Note: The previous classification of mild and moderate asthma have been combined into class sincetreatment is similar. C. Monitoring of Severity of Asthma

The use of the peak expiratory Sow meter is practical and is recommended for using both initialassessment and in monitoring the severity of asthma. 

D. Treatment: Control of Triggers

 Avoidance of triggers which includes irritant gases, weather changes, cold air, exercise, respiratoryinfections, certain foods, additives, drugs. These triggers cannot cause asthma to develop initiallybet can exacerbate estab1ished asthma.

 E. Goal in the Pharmacologic Therapy of Asthma

The goal in the management of asthma is to achieve control. Control of asthma is defined as:

Page 59: Medicine Blue Book

8/9/2019 Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 59/266

 1. Minimal (ideally no) chronic symptoms, including nocturnal symptoms2. Minimal (infrequent) exacerbations3. Minimal need for pm beta-2 agonist, ideally none4. No limitations on activities, including exercise5. (Near) normal PEFR6. PEF variability < 20 %

- Oral steroid > 7.5 mg daily or alternate days

RELIEVER:- Inhaled short-acting beta-2 agonistnot to exceed 3 - 4 X/day- Add inhaled Ipratropium bromide

 

 ALTERNATIVE RELIEVER:- Short-acting oral/ systemic bronchodilator (beta-2 agonist or theophylline)

 Guide to Treatment Plan: 

1. Patients should start treatment at the step most appropriate to the initial severity their condition. Arescue course of prednisone may be needed at any time and any step.2. When to Step up: If control is not achieved, consider step up. But first review patient medicationtechnique, compliance and environmental control.3. When to Step down: Review treatment every 3-6 months. If control is sustained for at least 3months, a gradual stepwise reduction in treatment may be started.

 Aminophylline} 

l. If hypercapneic, keep O2 low at 0.5-1.5 1pm via nasal cannula (so as not to depress patientsrespiratory drive). It is best to target O2 sat at 90-92 %.2. Ipatropium Br & Salbutamol (Combivent) nebulization is more effective than Terbutaline orSalbutamol nebulization. Or if feasible give Tiotropium(Spiriva HandiHaler) inhalation of 1 capsule daily.3. For acute exacerbations, give a course of intravenous or oral steroids.4. Long term home oxygen therapy if patient hypoxemic or with cor pulmonale.5. Treatment is symptomatic, only smoking cessation and home oxygen therapy have been shownto prolong life.

a. If with recent PPD conversion, give primary prophylaxis HR for 4 months or HE for 6monthsb. If not a recent PPD converter but currently exposed to a TB case, give primarily prophylaxisis as abovec. If not a recent PPD converter 4 no family member has active TB, may not give primaryprophylaxis

4. ATS Class 3: PTB active

In the National TB Control Program, only Class III(Active) patients are targeted for treatment forfinancial reasons. For operational purposes ATS Class 3 patients are farther subidvided into

WHO Category I, lI. and III.

 

Table 2-3 Treatment Regimen for ATS Class 3 Patients (PTB Active)

 

1.  WHO Category I*a.  TB patients: new smear-positive PTB; new smear negative PTB with extensiveparenchymal involvement; new cases of severe forms of extra-pulmonary TB.b.  Alternative TB Treatment Regimen

i. Initial phase: 2HRZE (four drugs)ii. Continuation phase: 4HR

 2.  WHO Category II

a. TB patients: Sputum smear-positive: relapse; treatment after interruptionb. Alternative TB Treatment Regimen

i. Initial phase: 2HRZES and 1HRZE (Five drugs)ii. Continuation phase: 5HRE

 3.  WHO Category III**

a. TB patients: New smear-negative PTB (other than in Category 1) new less severe formsof extra-pulmonary TB.b. Alternative TB Treatment Regimen

i. Initial phase: 2HRZ (three drugs)ii. Continuation phase: 4HR

 * Give this regimen if with high bacterial load, cavitary lesions, AFB+4 smears, or high communityresistance (e.g. NCR, Cebu, Davao, Zamboanga, Cavite, Pampanga). If with cavitary disease, giveStreptomycin IM alternate days (60 doses) instead of Ethambutol** May give this cheaper regimen for newly diagnosed TB and those cases found in low communityresistance Source: Maher D, Chavlet P, & Spinaci S, et el (1997).

Programmes (2nd Ed.. Geneva: World Health Organization. 5. ATS Class 4: Previous PTB disease (e.g. Chest X-ray with minimal infiltrates but no symptoms ofactive disease or previously treated PTB)

 

Treatment Algorithm

 Has patient completed past treatment of PTB?·  NO: Check old CXR if:

Page 72: Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 72/266

o  6 months stable CXR§  If age <60:4HR or 6HE§  (If age >60 Just observe)§  Repeat CXR after 3 months§  If infiltrates increase or decrease, treat PTB as Class III.. If infiltrates are stable, stop

treatmento  No previous CXR

§  Give 2HRZ/4HR§  Repeat CXR after 2 months§  If infiltrates increase or decrease, treat PTB as Class III.. If infiltrates are stable, stop

treatment 

·  YES: Observe and then Check old CXR if:o  X-ray normal with normal or less infiltrates

§  Treat as PTB 3, 2HRZE/4HR (or 2HRZ/4HR)

o  X-ray the same , no changes§  No treatment

 

6. ATS Class 5: PTB Suspect

Treatment Plan: Check previous Chest x-rayReclassify patient into Class III or Class IV in 2-3 months using sputum bacteriology or serial x-ray

changes. 

7. Multi-drug Resistant TB: Infection with strain of Mycobacterium tuberculosis which shows in-vitroresistance to at least Isoniazid and Rifampicin

Treatment Plans: Use at least 4-5 drugs as hng as,

a. Use at least 4-5 drugs as long as these include 2 drugs not previously taken. Do not add a single

drug to a failing regimen to avoid resistance to the new drug. Consider continuing with H & R (mostbactericidal) despite resistance, for example, if patient took HREZ X 6 months, may then addStreptomycin (first line drug) and Ofloxacin (second line drug. May discontinue either E or Z.b. Continue treatment for 18 months more from the time the patient’s sputum becomes AFB andculture negative. Get cultures to check sensitivity of TB organism.c. Consider Surgery for unilateral cavitary lesions in whom MDR-TB is established by the

laboratory. 

Legend: H or INH honiazidR or RIF = RifampicinZ or PZA PyrazinamideE or EMB = EthambutolS or STM Streptomycin 

I. Notes on Anti-TB Drug Intake: (Additional Treatment Plan for Active PTB)

l. Instill in the patient’s mind the need to complete 6 months treatment.a. Since it is very difficult for patients to comply with multiple drug for the duration of at least six

months, incomplete treatment not only decrease cure rate but also enhance development ofresistance. It is ideal that treatment of TB should be done under direct supervision. “DOTS”-

Directly Observed Therapy Short Course requires actual observation during drug intake. Thereare now several DOTS centers in Manila to help doctors implement DOTS treatment even forprivate patients. Refer patients to Manila Doctors Hospital, PGH, Makati Medical Center andUST.

b. Give all medications 1 hour before meals. It is ideal not to break the dose of the drug.c. If drugs are to be staggered because of side effects, make sure each drug component is still

single dose.e.g. Rifampicin - before breakfast, EMB - before lunch, PZA - before supper 

d. Use only fixed dose combination, since most of these contain only 450 mgRifampicin, add 150 mg Rifampicin if patient weighs > 60 kg or 130 lbs.

http://slidepdf.com/reader/full/medicine-blue-book 73/266

2. If patient cannot complete treatment, better not to start treatment at all to avoid emergence ofresistance (MDR-TB).3. The allowance for non-compliance is two weeks maximum, otherwise the treatment regimen shouldbe started all over again.4. Follow-up patients monthly. During initiation of treatment make patients follow- up after a week tosee if there are drug side effects.5. If after 6 months, the patient is still symptomatic, continue treatment but do sputum AFB and culture

and reassess if the patient has MDRTB or cured TB with bronchiectasis.6. Post-treatmeat follow-up: If two years has elapsed and the patient is still asymptomatic, long-term

cure is anticipated. Relapse occurs in 1-2 % of cases. 

J. Tuberculosis in Special situations:

1. Pregnancy:

a. HRE X 9 months (Standard regimen for pregnant patients)

b. Give 50 mg of Pyridoxine as vitamin supplements.c. Avoid PZA, especially in the first trimester, unless resistance to H and R ishighly suspected.d. Avoid Streptomycin: May cause 8th cranial nerve fetal abnormality.e. Breastfeeding is allowed: Take drugs after breastfeeding; TB drugs do not have toxic effect on

nursing newborns.

2. Uremia or end-stage renal diseasea 2 HRZ / 6 HR (Safest regimen for renal disease)b. Give INH + RMF +/- Pyridoxine at the regular doses administered after dialysis.c. Ethambutol: Decrease dose to 8-10 mg/kg/dayd. Pyrazinamide: Decrease dose to 12-20 mg/kg/daye. Avoid Streptomycin (nephrotoxic)

3. Liver Disease/ Drag-induced Hepatitis:

a. Stop anti TB drugs if (1) (+) jaundice or (2) Liver function test (SGOT, SGPT) > 3X the normalvaluesb. Slowly resume INH and Etlambutol during first week. Resume Rifampicin during the second weekand then PZA 3 days after.

4. Diabetes Mellitus: Continue treatment for a minimum of 9 months

5. Elderly patients > 65 years: Give HR X 9 months

6. Extrapulmonary Tuberculosis:

a. Same treatment regimen as pulmonary TBb. For Central Nervous System TB:

i.Use H, R, Z because of good penetration to the CNSii.EMB and STM penetrate inflamed meninges only.

7. PTB in Children (Primary Complex):

a. mixed disease: INH 5mg/kg/day (max of 300mg) + RMP 10mg/kg/day (max of 600 mg)

b. extensive disease: STM 10-18mg/kg/day (max of 750mg) or EMB 15-20 mg/kg/day – avoid in

young children whose visual acuity cannot be monitored, PZA 20-30 mg/kg/day (no studies yet)

1. Drugs with Anti-Pseudomonas properties: Aminoglycosides (Tobramycin, Netilmicin, Amikacin,Gentamicin), Ceftazidime, Cefoperazone, Quinolones (Ciprofloxacin), Ticarcillin and Piperacillin,Monobactams (Aztreonam), Carbapenems (Meropenem), Fourth Generation Cephalosporins (Cefepimeand Cefpirome) 2. Drugs with good anaerobic properties: Clindamycin, Metronidazole, Chloramphenicol, Cefoxitin,Meropenem, Ampicillin-Sulbactam, Amoxycillin- Clavulanic acid and high-dose Penicillin. 

3. Drugs with good central nervous system penetration in meningitis: Ceftriaxone, Ceftazidime,Cefiuoxime, Cefotaxime, Ampicillin, Meropenem, Ampicillin-Sulbactam, Ciprofloxacin, Penicillin G andVancomycin. Chloramphenicol and Co-trimoxazole have high diffusion to the cerebrospinal fluid evenwithout meningitis. 4. Drugs safe for patients with liver disease: Aminoglycosides, Ampicillin, Amoxicillin, Cephalexin,Cefoxitin, Cefiaoxime, Ofloxacin, Penicillin G and Carbepenems.

 5. Cephalosporins:

a. Fourth Generation Cephalosporins have the same indications as Third GenerationCephalosporins and should remain as "reserved" drugs.b. The only two Third Generation Cephalosporins active against Pseudomonas are Ceftazidimeand Cefoperarone. Cefoperazone may cause bleeding in predisposed patients.c. Cephalosporins that cross the blood-brain barrier. Ceftriaxone, Ceftazidime, Cefotaxime,

Ceftizoxime.d. Cephalosporin with best anaerobioc coverage: Cefoxitin. Other Cephalosporins also have someanerobic properties.e. Cefuroxime axetil is given with meals.f. Cefazolin is the drug of choice only for surgical prophylaxis of abdominal operations and implantsurgery.

 6. Aminoglycosides

a. Aminaglycosides are given q 8-12 hours in 30 minutes by slow IV or IM to avoid, possibleneurornuscular paralysis. They must have loading doses, and should be given for < 7 days to

Page 105: Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 105/266

avoid nephrotoxicity. Creatinine is measured every 3 days.b. Amikacin: Expensive but it is the most potent and least nephrotoxic. Loading dose = 7.5 mg/kg,Maintenance dose = 15 mg/kg/day in 2 divided doses IM, IVc. Gentamicin, Tobramycin, Netilmycin, Loading dose = 2 mg/kg, Maintenance dose = 1.5mg/kg/dosc q S hours IM, IVd. Gentamicin is the cheapest aminoglycoside. Spectinomycin is used for gonorrhea Streptomycinis used for PTB.

 7. Macrolides

a. Erythromycin is given with meals. If with GI upset, lower the dose.b. Azithromycin is given 1 hour before meals.

 8. Rifampicin

 Aside &am anti-TB pmperties, Rifampicin naybe used synergistically with Oxacillin forS. aureus.Resistance may develop when Rifampicin is used alone.

HYPOKALEMIATo Nephrology Page

To Main Table of ContentsTo Detailed Table of Contents

 Data:

 A. Etiology: Diarrhea, laxative abuse use diuretics vomiting, check for hypertension (hyperaldosteronism orglucocorticoid excess), renal tubular acidosis, polymyositis, hypokalemic peroidic paralysis. B. Principles of Management of Hypokalemia:,

1. The clinical context dictates the need for therapy of hypokalemia. Hypokelemia per se does notnecessarily justify treatment with potassium supplements or potassium sparing diuretics.2. Assess the etiology (redistribution versus deficit) of the hypokalemia.3. Assess and correct acid-base balance and extracellular fluid volume abnormalities.4. Assess the level of renal function5. Assess and correct serum tonicity and serum magnesium, if needed.6. Normokalemia or hypokamia in a context of metabolic acidosis or serum hypertonicity oftenindicates potassium deficits.7. Potassium-sparing diuretics should not be used in patients at risk (patients with decreased renalfunction or patients receiving drugs impeding potassium homeostasis).

8. Only resistant hypokalmia justifies the use of two simultaneous treatment modalities ofhypokalemia.9. Assess the potential attribution of medications to hypokalemia and the underlying pathophysiologycausative of hypokalemia and correct whenever possible.10. Evaluate concurrent medications and/or existing clinical conditions that may aggravate theconscqueneps, of hypokalemia11. Discontinue treatment of hypokaiemia whneever concentration is about 3.5-4.0 meq/l for fear of"overshoot" hyperkalemia or until a pattern of response is clearly established.12. Whenever treating hypokalemia, follow the response to treatment by serial measurements ofserum potassium concentration and if indicated, acid-base status.13. The oral route of potassium replacement, using potassium chloride, is the safest andthe preferred modality of treatment. The intravenous route of therapy should be reserved forextreme situations.

 C. Estimation of Potassium Deficit:

1. For a fall in serum potassium from 4.0 to 3,0 meq/l body potassium deficit is 200-3000meq/70kg body weight

2. For serum potassium at 2.5 meq/L body deficit is 500 meq/70 kg body weight3. For serum potassium at 2.0 meq/L body deficit is 700 meq/70 kg body weight

 

Orders:

Diagnostics: CBC, Serum K, repeat Serum K in 2-3 days

Na, Ca, Mg, ABG

Urine K, Urinalysis

 

Therapeutics:

 1. The oral route of administration is the safest and preferred mode of potassium replacement. Oralpotassium should be given preferably as liquid with or after meals, or as tablet, which must be swallowedand not allowed to dissolve in the mouth; Dose depends on the clinical situation and the estimated deficit.

e.g. Per Orem: Kalium durule 0.75gm (10 meq) TlD PO X 2-3 daysor Oral KCl Solution 15-30 cc TID (1 gm KC1 = 14 meq K+) to be further diluted in oral feeding or

water.Note: Each oral dose should not exceed 20-40 meq K+

 2. When potassium is provided by the intravenous route the use of peripheral vein is preferred over a

Page 147: Medicine Blue Book

8/9/2019 Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 147/266

central route. The maximum rate at which potassium can be safely given into peripheral veins is usually10-20 meq/hour. Higer rate maybe administeres if the clinical situation warrants more rapid correction ofthe hypokalemia. Usual concentration is 20-40 meq potassium in 1 liter of saline or dextrose solution. Onemust be aware of a decrement in serum potassium of about 0.2-1.4 meq/liter when potassium isadministered glucose solute. 

e.g. Intravenous: Add 20-60 meq KCl in Plain NSS X 12 hours

If potassium level is < 2 and (+) ECG abnormalities use glucose-free solution. When fluidrestriction is necessary, up to 20 meq per 100 ml can be cautiously given over 1 hour via amicrodrip. Higher concentrations of KCI may cause skin burns.

 3. In the setting of severe hypokalemia, potassium can be delivered into the femoral vein with the tip of the

catheter not in dose proximity to the heart The rate of administration should not exceed 60 meq/hour.

DIALYSISTo Nephrology Page

To Main Table of ContentsTo Detailed Table of Contents

  A. Dialysis Indications: When to start dialysis

1. Subjective symptoms of uremia2. Creatinine clearance of 10 ml/min for non diabetics or 10-20 ml/min for diabetics3. Pulmonary edema, severe hypekalemia or metabolic acidosis

B. Absolute Contraindications to Dialysis:1. Hemodialysis: No vascular access possible2. Peritoneal Dialysis:

a.. Loss of peritoneal function producing inadequate clearanceb. Adhesions blocking dialysis flowc. Surgically uncorrectable abdominal herniad. Abdominal wall stomae. Diaphragmatic fluid leakf. Inability to perform exchanges

C. Acute Hemodialysis (HD) Prescriptions

1. Session length: 2 hours‘(or post hemodialysis BUN of approximately 70% of pre- hemodialysis

BUN)2. Blood flow rate: 200 ml/min3. Dialysis solution: Bicarbonate dialysis4. Fluid removal orders: Remove 2.2 liters at a comstant rate (May do initial fluid ultrafiltration forpulmonary congestion or pulmonary edema5. Anticoaguhtion orders:

a. Routine heparin prescription: 2000 units initially then heprain infusion into the arterial line at1000 units per hour b. Heparin free prescription:

i. Heparin rinse: Rinse dialyzer Wth NSS 1 liter plus 3000 units heparin then flush withunheparinized saline or patient’s bloodii. High blood flow rate: 250-300 million if tolerated. Periodic saline rinse: 100-250 salinewhile occluding the blood inlet line every 15-30 minutes. Adjust the ultrafiltration wee toremove the excess fluid.

c. Low molecular weight heparins6. Common complications during dialysis

a Hypotensioni. Place patient in Trendelenberg positionii. Saline bolus (100 cc or more) through the venous blood line or 10-20 cc hypertonic salinebolusiii. Reduce ultrafiltration rate to zeroiv. Oxygen inhalation if necessary

b. Muscle crampsi. Usually occurs in association with hypotension (Give above measures)ii. Hypertonic saline or hypertonic glucose bolus

 D. Acute Peritoneal Dialysis (PD) Prescription:

1. Check abdomen for abdominal masses & previous surgeries. Opt for open insertion if the above

are present2,.; Procedure for Insertion of the Catheter.

a The stylocatheter is to be inserted within 1 cm below the umbilicus at the midline.b. Properly disinfect the skin, especially the umbilicusc. Inject local anesthesia (Xylocaine 2%) up to the peritoneal fasciad. Stab skin with a scalpel blade no. 11 then insert catheter together with the stylet undercontrolled pressuree. Entryinto the peritoneum is made when a “give’” is felt. Withdraw the stylet for a few millimetersand direct the blunt catheter into the right lower quadrant.f. Connect the catheter to the administration set.

3. Peritoneal Dialysis Ordersa. Use 1.5 % dialyzing solution (Inpersol); may use 2.5 % or 4.25 % for poor drainageb. Use 1 liter for the first few exchanges then shift to 1.5 to 2.0 liters if toleratedc. One exchange time usually involves the following:

Infusion time = 5-10 minutesDwell time = 20-30 minutesDrain time = maximum of 30 minutes

d. For fluid removal, use a more hypertonic solution, e.g. 4.5% dialyzing solutione. For solute removal, use a larger volume of dialyzing solutionf. For poor drainage, try the following maneuvers:

i. Change position of the patientii. Incorporate heparin 500-1000 units per liter of dialyzing solution if without bleedingproblemsiii. Use a hypertonic solutioniv. If above maneuvers fail, reinsert catheter 

g. Oral potassium supplements if serum potassium is < 4 meq/L.h. Shift to Tenckhoff catheter after 72 hours, if kidney failure is not reversible.i. Record fluid balance accurately in a separate sheet.

 3. Diagnosis of Diabetes: Based on 2004 ADA Recommendation

a. FBS > 126 mg/dl (7.0 mmol/L) on two separate occasions;b. Following ingestion of 75 gm of glucose: Blood sugar > 11.1 mmol/L (200 mg/dl) at 2 hourspost-prandial and at least one other occasion.Note: Normal Fasting Blood Sugar is < 100 mg/dl (< 5.6 mmol/L)Impaired Fasting Glucose is 100-125 mg/dl (5.6 – 6.9 mmol/L)

4. Goals of Treatment:

a. Hemoglobin A1C < 7%b. Fasting Blood Sugar between 5.0-7.2 mmol/L (90 -130 mg/dl)

c. Peak post-prandial glucose < 10 mmol/L (180 mg/dl)5. Diabetic Management:

 A. Non-pharmacologic (Step 1)1. Diabetic Diet (see Nutrition chapter)

Ideal Body Weight = [(Height in inches X 2.54) - 100] - 10% (if female)Ideal Body Weight X 35 cal/Kg = Total calories/daySample: Total calories = 2000 cal/day60% Carbohydrate: Total cal/day X 0.60 = 1200 cal /4 = 300gm carbo220% Protein: Total cal/day X 0.20 = 400 cal / 4 = 100 gm protein20% Fat: Total cal/day X 0.20 = 400 cal / 9 = 45 gm fat

2. Exercise regularly.3. Weight reduction for overweight patients.

B. Pharmacologic (Step 2): Oral Hypoglycemic Agents

 

Sample Treatment for Type II Diabetes Mellitus 

Step 1: Non-pharmacologic treatmeat: Diet, exercise, weight reduction

Step 2: Oral Hypoglycemic Agents

a Start with Sulfonylareas:e.g. Start older patients with Glipizide (Minidiab) and younger patients with GlibenclamideBegin with low doses then maximize dose if blood glucose is uncontrolled Target FBS of =140 mg/dl. Adjust dose every 2 - 4 weeks.

-/+ b. Add Biguanides if still uncontrolled with Sulfonylureas: e.g. Metformin 500 mg tab TID

Page 165: Medicine Blue Book

http://slidepdf.com/reader/full/medicine-blue-book 165/266

-/+ c. Add Alpha-glucosidase inhibitor  if with post-prandial hyperglycemia: e.g. Acarbose

(Glucobay) 50-100 mg tab TID w/ first mouthful of food.+ d. Add Thiazolinediones (insulin Seasitizers): e.g. Rosiglitazone (Avandia ) 4 - 8 mg tab OD

units at 6 a.m. Humulin N 7 units, Humulin R 3 units at 6 p.m. b. BIDS (Bedtime Insulin and Daytime Sulfonylureas)

Combined Insulin & Oral hypoglycemic agentse.g. Diamicron 80 mg 1 tab TID PO 30 minutes before mealsHumulin N 10-20 units SC at night

 

c. Insulin + Oral Hypoglycemic Agents:

 Add Insulin treatment on top of Oral hypoglycemic agentsChoose any of the 3 regimens in No.1 (usually Single-dose or Split-dose)eg. Humulin N 20 units SC at 6 a.m. single-dose+ Diamicron 80 mg I tab TID 30 minutes premeals

 3. Blood Sugar Monitoring of Patients:

a. Out-patient: Two hours post-prandial, FBS, Hgb A1Cb. In-patient: CBG (Capillary Blood Glucose) monitoring

CBG OD = 6 a.m. premeals or 2 hours post-prandial (after) lunchCBG BID = 6 a.m. - 6 p.m. premealsCBG TID = 6 a.m. - 12 noon - 6 p.m. premealsCBG QID = 6 a.m. - 12 noon - 6 p.m. - 12 midnight premeals

 4. How to Calculate the Daily Insulin Requirement of an In-patient.

Step 1: Use Insulin Sliding Scale for 1 day only to observe daily insulin requirement of the patient.CBG < 160 = no insulinCBG 160 - 200 = 4 units Humulin R SCCBG 200-300 = 6-10 units Humulin R SCCBG 300-400 = 10-14 units Humulin R SCCBG > 400 = call Attending Physician

Step 2: Get total daily Insulin requirement to achieve reasonable control. e.g. 30 units needed for theday

Step 3: For patients on oral diet give 2/3 of total daily Insulin requirement in the morning and 1/3 in theevening

e.g. Humulin N 20 units SC at 6 a.m. + Humulin N 10 units SC at 6 p.m.Step 4: For patients on oral NGT feedings round the clock, give 1/2 of total daily dose at 6 a.m. and1/2 at 6 p.m.

e.g. Humulin N 15 units SC at 6 a.m. + Humulin N 15 units SC at 6 p.m.Note: Give additional short-acting insulin as rescue doses for CBG > 200 mg %

 5. For Type I Diabetes Mellitus: Refer these patients to an Endocrinologist for strict insulin treatment.

 * In patients with severe thyrotoxicosis, points are assigned to the highest possible weighted descriptionapplicable in each category and scores totaled. When it is not possible to distinguish the effects of anintercurrent illness from those of the severe thyrotoxicosis per se, points are awarded such as to favor thediagnosis of storm and hence empiric therapy. A score of 45 or greater is highly suggestive of thyroidstorm; a score of 25-44 is suggestive of impending storm, and a score below 25 is unlikely to re representthyroid storm. Source: Burch, H.B. & Wartofsky, L.

Diagnosis: The American College of Rheumatology 1987 Revised Criteria for the Classificationa ofRheamatoid Arthritis:

 l. Guidelines for Classification

a Four of seven criteria are reuired to classify a patient as having rheumatoid arthritis. (Sensitivity

= 91-94% Specificity = 89%)b. Patients with two or more clinical diagnoses are not excluded.

2. Criteria*a. Morning stiffness: Stiffness in and around the joints lasting one hour before maximal

improvement.b. Arthritis of three or more joint areas: At least three joint areas, observed by a physician

simultaneously, have soft tissue swelling or joint effusion not just bony overgrowth. The 14possible joint areas involved are right or left proximal inter-phalangeal, metacarpophalengeal,

wrist, elbow, knee, ankle, and metatarsophalangeal joints.c. Arthritis of hand joints: Arthritis of wrist, metacarpophalangeal joint, or proximal interphalangeal

 joint.d. Symmetric arthritis: Simultaneous involvement of the same joint areas on both shies of the

body.e. Rheumatoid nodules: Subcutaneous nodules over bony prominences, extensor surf' or

 juxtaarticular regions observed by a physician.f. Serum theumatoid factor : Demonstration of abnormal amounts of serum rheumatoid by any

method for which the result has been positive in less than 5 percent of normal control subjects.g. Radiographic changes: changes: Typical changes of rheumatoid arthritis on posteroanterior

hand and wrist radiographs which must include erosions or unequivocal bony decalcificationlocalized in or most marked adjacent to the involved joints.

 * Criteria a-d must be present for at least 6 weeks. Criteria b-e must be observed by a physician.

2. Pharmacologic treatmenta. ASA and other NSAIDSb. Low glucocorticoids: Prednisone 5 mg tab to be given at 2.5-7.5 mg/day

Vary the dose dependirig on the disease activityc. For moderate to severe end/or sustained disease activity, may use the following:

i. Disease-modyfying anti-rheumatic drugs: Gold anti-malarials methotrexate, Leflunomide(Arava)ii. Immunosuppressive therapy: Azathioprine, Cyclophosphamide, Cyclosporins

iii. Anti-TNF alpha therapy: Enbrel or Infliximabiv. Anti-interteukin therapy 

Note: At present, it is the consensus that combination therapy of NSAIDS, low dose steroids anddisease modifying drugs including anti-cytokine therapy be started as early as possible especiallywith very active disease. Since each of these drugs is associated with considerable toxicity, it is bestto refer these patients to a Rheumatologist

CEREBROVASCULAR ACCIDENT: INFARCTION VS. HEMORRHAGE 

To Neurology PageTo Main Table of Contents

To Detailed Table of Contents 

There are currently far available stroke scoring systems to differentiate supratentorial brainhemorrhage from infarction. All of these stroke scores have recently been validated at the UP-PGHMedical Center and the results show that the Siriraj Scoring and Allen Scoring have the highest sensitivity(80-85 %) and specificity (70-80 %). Our preference is the Siriraj Stroke Score (See Table 8-1) becauseof its simplicity. Note also that no scoring system is 100% accurate. Therefore, in case of doubt, do statCT Scan.

 * Sample scoring for a hypothetical 50 year old male t with an acute shake syndrome. On consultation, he is alertand has complained of vomiting and headache after the onset of left-sided weakness. He has a history of diabetesmellitus and blood pessure is 150/90 mmHg. Based on this information, the patient’s stroke score per variable is given in the right-hand column. The total score is+ 4, which is above the cut-off of 2 points, indicating a bable hemorrhagic stroke.

 Score Interpretation:

= +2 = Most likely HEMORRHAGE- 1, 0 and+ 1 = Equivocal result (CT Scan recommended)= -2 = Most likely INFARCTION

petroleum ingestion.4. Cathartics (Sodium sulfate)

a. Contraindicated in infants, acid and alkali ingestion, patients who will receive an oralantidote, adynamic ileus severe diarrhea, abdominal trauma, surgery, suspected intestinalobstruction, severe elctrolyte loss or dehydration. Magnesium sulfate cathartics are

contraindicated in renal 5ailufailure. Sodium sulfate is contraindicated in hypertension andheart failure.

b. Sodium sulfate 15-30 grams (or 250 mg/kg) in 100 ml water given 30 minutes aper theactivated charcoal. If still without bowel movement within one hour, may repeat procedure.

5. Forced Diuresis

Warning: Forced diuresis should only be attempted in treatment centers that can monitor hydrationand electrolyte status of patients.

a. Forced Diuresis: Maintain urinary flow rate of 5-7 ml/kg/hr by infusing normal saline andintermittent boluses of Furosemide 20 mg IV doses. Alternatively, use mannitol 20-100 gm IV,maximum 300 gm Monitor electrolytes and state of hydration.

b. Forced Alkaline Diuresis: May be useful for phenobarbital, mephobarbital, primidone,

salicylates, lithium, isoniazid. Adult dose: Sodium bicarbonate 1-2 amp IV followed bycontinuous IV infusion of 1-2 ampules (50-100 mEq) of sodium bicarbonate in 1 liter of

0.25-0.45 and normal saline at 250-500 ml/hr the first 1-2 hours. Maintain the urine pH of7.3-9.0. Add additional 0.45% normal saline and intermittent doses of Furosemide 20 mg IV.Increase urine output to 2-3 ml/kg/hour.

 

6. Miscellaneous Antidotes

a Extrapyramidal reactions to Pheaothiazines or Metoclopromide

Diphenhydramine 25-50 mg IV or IM q 6 hours X 4 doses; followed by 25- 50 mg IVor PO q 6hours for 24-72 hours PRN.b. Benzodiazepine overdose (e.g. Diazepam, Midazolam, Lorazepam)

Flumazenil 0.5 mg/5 ml ampule: 0.2 mg IV q 5-15 minutes until the patient wakes up er until 1 mgis reached. Consider gastric emptying, activated charcoal. Administer cathartic and conservativesupportive therapy.

 

C. Guidelines for Nurses: 

1. When antidotes are ordered, it is meant to be given immediately or at least reasonably within thehour in some cases. They are not given when it is the next convenient dosing period for thenurses (i.e. TID, q 6 hours)

2. Always check with the Pharmacy for the available antidote or the Poison Center before asking thepatient to purchase these at outside pharmacy outlets because these special drugs may not becommercially available. Inform the doctor at once when it is known that these drugs are notavailable. Some special antidotes are available in the PGH Central Block Pharmacy telephoneNo. 521-8450 local 3163). Examples are N-acetylcysteine, N-acetyl penicillamine and succimer.These may be requested for use by the hospital in need but should satisfy two requirements: (a)the attending physician shouid sign a waiver freeing PGH of any liabilities from the use of suchantidotes and, (b) a toxicology consultant is preferably invited to co-manage the case.

 Available commercially and at PGH Central Block Pharmacy (Tel. No. 521-8456 local 3163).a. Dosage and administration: An initial dose of 150 mg/kg body weight of N-acetylcystine is

infused in 200 ml 5% dextrose IV over 15 minutes, followed by an IV infusion of 50 kg/kg in500 ml 5% dextrose over the next 4 hours, then 100 kg/kg in 1 liter 5% dextrose over thenext 16 hours. (This gives a total dose of 300 mg/kg in 20 hours.)

b. N-acetylcysteine is very effective in preventing Paracetamol-induced hepato-toxicity whenadministered during the first 8 hours after a paracetamol overdose. When administeredafter the first 8 hours, the protective effect diminishes progressively as theoverdose-treatment interval increases. However, clinical experience indicates that N-acetylcysteine can still be of benefit when administered after 24 hours in patients at risk of

severe liver damage. In general, for patients presenting later than 24 hours after aparacetamol overdose, guidance should be sought from PGH Poison Control Center.c. Treatment nomogram (See Figure 9-1): Plasma paracetamol concentration in relation to

time after the overdose is commonly used to determine whether a patient is at risk ofhepatotoxicity and should therefore receive treatment with an antidote such asN-acetylcysteine.

a Alkaline diuresis to maintain urinary pH at approximately 8.0 by giving sodium bicarbonate IV [100mEq of sodium bicarbonate (2 amps) in 1 liter of D%W at 10-15 ml/kg/hr]. Monitor urine output,urine pH and serum K, and increase alkalinization at a tate of 2-3X maintenance rate fluidrequirement if the patient is dehydrated, until urine flow is adequate. Follow arterial pH closely toavoid excess systemic alkalinization. Watch closely for signs of fluid overload.

b. Hemodialysis is indicated for initial salicylate level > 160 ml/dl or when 6-hour level is > 130 mg/dl orwhen profound acidosis (pH < 7.1); or when there is renal failure, severe CNS dysfunction;pulmonary edema or deterioration despite supportive therapy.

c. Other treatments:i. Acidemia: IV Sodium Bicarbonateii. Seizures: IV diazepamiii. Pulmonary edema: Treat with high concentrations of oxygen, furo-semide and positive

end-expiratory pressure ventilationiv. Cerebral edema: Treat with hyperventilation and osmotic diuresis with Mannitol

 1. Indication: Hyperurecemia (high uric acid levels), gout

2. Low purine diet is about 120-150 mg/day whereas regular diet contains as much as 600 to 1000mg/day. Diet should be relatively high in carbohydrate and low in fat since since carbohydrates havebeen shown to favor uric acid excretion while fats tend to favor retention. A liberal intake of fluids ishelpful in eliminating excess uric acid and in minimizing calculi formation.

Nutritional Management of Diabetics and Renal Patients 

To Nutrition PageTo Main Table of Contents

To Detailed Table of Contents1. Nutritional management of Diabetes Mellitus:

a. Total calories - sufficient to maintain reasonable weight in adults, or meet increased needs ofchildren, adolescents, pregnant and lactating women and individuals recovering from catabolic illness.

b. Caloric distributionCarbohydrates: 50-70%Protein: 10-20%Fat: 20-30%

c. If obesity and weight loss are the primary issues, use the lower fat levels (20-25%) of total calories.d. Cholesterol - limit to 300 mg/day or lesse. Carbohydrates and sweeteners

Non-nutritive sweeteners: Aspartame may be used in moderationDietary fiber: Aim for about 20 grams/day or more. Excessive amounts are not necessary.It is best to limit the use of sucrose and sucrose containing foods.

f. Sodium - limit to about 3000 mg/day; less for people with hypertension or renal complicationsg. Alcohol - moderate amounts may be allowed, contingent on good metabolic control

h. Vitamin and mineral supplements - not usually necessary, but may be given to individuals on reducedcalorie diets (1000 kcal/day or less)

 2. Nutritional Management of Chronic Reaal Insufficientcy (CRI)

a. The diet for chronic renal inefficiency is also called predialysisdiet . The diet is restricted in two majornutrients: protein and phosphorus. Restrictions in sodium, postassium, fluid and calories are basedon individual needs. Because of restrictions in certain foods, the diet is deficient in calsium, iron,Vitamin B12 and zinc. The diet.aims to reduce the workload of the diseased kidney(s) by reducing theurea, uric acid, creatinine and eleetrolytes (especially phosphates) that must be excreted andpostpone the need for dialysis.

To Main Table of ContentsTo Detailed Table of Contents

 Data:

l. Avoid Dilantin, Warfarin ACE inhibitors and Angiotensin II antagonists.2. Nearly all CVS drugs cross the placenta and are excreted in breast milk.3. Most drugs should be avoided in the first trimenster inless the cardiac condition demands urgenttreatment4. Diuretics should not be in bipedal edema unless there is frank pulmonary congestion. Diuretics maydecrease uterine blood flow

 Treatment Options:l. Inotropic agents - Digitalis is safe, Dopomine is reserved for life threatening situations only.

2. Vasodilators - Hydralazine is safe

Use Nitrates as in the non-pregnant state

Nitroprusside reserved for life threatening situations only. Avoid ACE inhibitors and Angiotensin II antagonitsts

3. Calcium-channel blockers - Verapamil and Nifedipine are relatively safe.

4. Beta-blockers - May be used for short period to time there are no alternatives.Side effect: intrauterine growth retardation, bradycardia

 

5. Anticoagulants/Antiplatelets - Warfarin conraindicated especially in the first trimester (20% teratogenic)Heparin SQ can be given, It does not cross the plaenta

ASA and Dipyridamole can be given with slight increase in bleeding

ALL ABOUT DRIPSTo Main Table of Contents

To Detailed Table of Contents

 

How to use the listed drip rates and equivalent dosages given:  For example, the statement under number one for the daomine drip sees, “Drip of 2.5-10mcg/kg/min is equivalent to 9-38 ugtts/min for a 50 kg patient.” This means that a dopamine drip of 2.5mcg/kg/min is equivalent to giving 9 ugtts/min for a 50 kg patient while a dopamine drip of 10 mcg/kg/minis equivalent to 38 ugtts/min for a 50 kg patient. Using similar statements below as your guide, no tediouscomputations maybe necessary for the average patient. 1. Aminophylline Drip: D5W. 250 ml+ Aminophylline 250 mg/amp at 15-40 ugtts/min

Maintenance Drip of 0.4-0.8 kg/kg/hr is equivalent to 20-40 ugtts/min for a 50 kg patient.Formula: ugtts/min= dose x BWLD = 5 mg/kg BW in 30 ml D5W in a soluset (if patient is not maintained on oral theophylline)

Note: Maintenance infusion rate must be reduced to 0.2-0.3 mg/kg/hr for elderly patients,pregnant patients and those with CHF, liver disease or cor pulmonale

 

2. Amiodarone (Cordarone) Drip:Preparation: 150 mg/3 ml viala IV Loading Dose: 5-10 mg/kgbody weightt/24 hour or 500-1000 mg in 24 hours

Intravenous loading doses were given for an average of 4 days in clinical trials.Estimated maximum daily dose of 1000 rng/24 hours for Filipinos.

  Orders: Give 150 mg slow IV push over 10-30 minutes (with BP and HR monitoring)followed by D5W 250 ml+ 150 mg-300 mg IV Amiodarone to run for 24 hours. Supplemental dosesof 150 mg IV over 10-30 mins may be given for recurrent arrhythmias especially during the earlyphases of dosing. No more than six additional boluses in any 24 hour period may be given.

 Or b. Oral loading dose: 10 kg/kg body weight per day for two weeks

e.g. Amiodarone 200 mg 1 tab PO TID for 14 daysThen maintenance of 200 mg 1 tab OD thereafter.Source: Adapted from Kowey, P., Marinchak, R., Rials, S. et al (1997).

Intravenous amiodarone. JACC, 29, 6, 1190-8. 

3. Clonidine (Catapres) Drip:

Concentration=150 ug/m1 ampuleD5W 250 ml+ Catapres 2 amps (150 mg/amp) at 5-30 ugtts/min 

4. Clonidine/Hydralazine (Catapres/Apresoline) Drip:

D5W 250 ml+ Apresoline 2 amps (20 mg/amp) + Catapres 2 amps (150 mg/amp) at 5-30ugtts/min (Up to 60 ugtts/min)

 5. Diazepam (Valium) Drip:

D5W 100 ml+ Diazepam 10 mg q 6 hours (maximum= 60 mg/day) 

6. Dobutamine Drip: D5W 250 ml + Dobutamine 250 mg/amp at 10-60 ugtts/min

Drip of 2.5-20 mcg/kg/min is eguivalent to 80-60 ugtts/min for a 50 kg patient.Formula ugtts/min=(drip mcg x BW)/16.6If with CHF, may use double dose: D5W 250 ml+ Dobutamine 500 mg (2 amps) at maximum rateof 30 ugtts/min

 7. Dopamine Drip: D5W 250 ml+ Dopamine 200 mg/amp at 7-60 ugtts/min

Drip of 2.5-10 mcg/kg/min is equivalent to 9-38 ugtts/min for a 50 kg patient.Formula: ugtts/min=(drip mcg x BW)/13.3If with congestive heart failure (CHF), may use double dose: D5W 250 ml + Dopamine 400 mg (2
