Jan Bazner-Chandler RN, MSN, CNS, CPNP

Allergic Rhinitis

Assessment Itching of nose, eyes, and throat Sneezing and stuffiness Watery nasal discharge / post nasal drip Watery eyes Swelling around the eyes

Assessment

Allergic Shiner Allergic Salute

eMedicine.com

Rhinitis Interdisciplinary Interventions Avoid offending allergen – smoke / pets Pharmacologic management:

Oral or nasal antihistamines - Benadryl Leukotriene modifiers - Singulair Mast cell stabilizers – cromylin – nasal /

ophthalmic / inhaled Allergen-specific immunotherapy

Do not use combination OTC medications especially those that contain pseudoephedrine

No OTC Antihistamines for children under 6 years of age.

Sinusitis

Adam.com

Assessment Fever Purulent rhinorrhea Nasal congestion Pain in facial area Malodorous breath Chronic night-time cough

Children more prone to sinusitis: children with asthmaand cystic fibrosis.

Interdisciplinary Interventions Normal saline nose drops Warm pack to face Acetaminophen for pain Increase po fluid intake Antibiotics

Recent studies question their effectiveness

Tonsillitis Tonsils and adenoids are important to the

normal development of the body’s immune system.

Serve as part of the body’s defense against infection

Can become the site of acute or chronic infection

Repeated acute infections cause the tonsil tissue to swell

Enlarged tonsils and adenoids impinge on the pharyngeal opening of the eustachian tube

Assessment Child may refuse to drink Fever Reddened pharynx and tonsils Most common causative agent = group A

beta-hemolytic stretococci Chronic tonsillitis may result in snoring due to

enlarged tonsils and adenoids

Tonsilitis

“Kissing tonsils” occur when the tonsils are so enlarged they touch each other.

Interdisciplinary Interventions Throat culture to determine causative agent Antibiotics for ten days if throat

culturepositive for beta strep Acetaminophen for pain Cool fluids Saline gargles Antiseptic sprays Viral throat infections will not get better faster

with antibiotics.

Tonsillectomy Done if child’s respiratory status is

compromised Post operative care:

Side lying position Ice collar Watch for swallowing Cool fluids / soft diet

Croup Most common acute respiratory condition

seen in early childhood. Highest incidence from 6 months to about 3

years Respiratory symptoms are caused by

inflammation of the larynx and upper airway, with resultant narrowing of the airway.

Severity depends on the area of the upper airway that is inflamed and narrowed.

Most often viral – antibiotics are not needed

Assessment

Symptoms: Hoarseness Inspiratory stridor Barking cough Afebrile Often worsens at night

Interdisciplinary Interventions Home care:

Cool mist Fluids

Hospital care: Racemic epinephrine inhalant Mist tent – not used much anymore Dexamethasone IV fluids if not taking po fluids

Epiglottitis

Tripod position

Bowden & Greenberg

Acute Epiglottitis Acute inflammation of supraglottic structures,

the epiglottis and aryepiglottic folds. True pediatric emergency Delayed treatment may result in complete

airway obstruction Most often seen in children 2 to 7 years Most common causative agent – H. influenzae

type B

Assessment Sudden onset High fever – 102.2 or greater Dysphasia and drooling Agitation, irritability and restlessness Epiglottis is cherry red and swollen Note: Do not look into the mouth – diagnosis

often made by presenting symptoms or lateral neck x-ray

Interdisciplinary Interventions Keep child quiet in a controlled medical

environment with emergency airway equipment readily available.

Do not put tongue blade in mouth to look in the throat – may cause epiglottis to spasm and shut

Assess respiratory status Give humidified oxygen by mask and keep

HOB elevated. Mild sedation may help the child relax

Apnea Apnea is cessation of respirations lasting

longer than 20 seconds.

Monitor in hospital for underlying problems

Discharge home with monitor

Foreign Body

Severe inspiratory stridor

Symptoms depend on location

Unilateral chest movement

Chest x-ray Bronchoscope to

remove object

Coin in Trachea

Teaching No small hard candies, raisins, popcorn or

nuts until age 3 or 4 years Cut food into small pieces No running, jumping, or talking with food in

mouth Inspect toys for small parts Keep coins, earring, balloons out of reach

Influenza Associated with community epidemic Febrile, URI, achy joints Management:

Acetaminophen for fever Fluids Keep away from others Watch for signs of pneumonia

Bronchiolitis Acute obstruction and inflammation of the

bronchioles. Most common causative agent: Respiratory

Syncytial Virus (RSV) Bronchioles become narrowed or occluded as

a result of inflammatory process, edema, mucus and cellular debris clog alveoli

Assessment Harsh dry cough Low grade fever Feeding difficulties Wheezing Respiratory distress with apnea Thick mucus

Interdisciplinary Interventions Oxygen to maintain oxygen saturation >than

95% Pulse oximeter Nasal suction as needed Chest percussion to mobilize secretions Inhalation therapy – not sure if it is beneficial Mechanical ventilation as needed if increased

work of breathing is seen Increased heart rate, poor peripheral perfusion,

apnea, bradycardia and hypercarbia

RSV Positive - Isolation Respiratory Syncytial Virus is spread from

respiratory secretions through close contact with infected persons or contact with contaminated surfaces or objects.

Patient should be on contact and respiratory isolation

Can be placed with other RSV + patients

Pneumonia An inflammatory condition of the lungs in

which alveoli fill with fluid or blood resulting in poor oxygenation and air exchange.

Can be primary illness or develop as a complication of another illness.

Incidence: 34 to 40 cases per 1000 children younger than 5 years

Most likely to develop when the body is unable to defend against infectious agents.

Typical X-ray

Assessment High fever Thick green, yellow, or blood tinged secretions Grunting respirations Rales, crackles, diminished breath sounds Cough and cyanosis Diagnostic tests: Infiltrate seen on x-ray

Interdisciplinary Interventions• Assess for respiratory distress• NPO (respiratory rate > 60 = high risk for

aspiration)• IV fluids for hydration • Supplemental Oxygen to keep oxygen

saturation equal to or > 92%• Chest percussion• Nasal suctioning as needed• Acetaminophen for fever • Antibiotics – ampicillin and an aminoglycoside

(Gentamicin)

Pneumonia Isolation Respiratory isolation May be taken off isolation if RSV negative and

on antibiotics for 24 hours.

Cystic Fibrosis Inherited autosomal recessive disorder of the

exocrine glands Gene responsible for CF is located on

chromosome 7 Life span is about 37 years Complex disease requiring a holistic approach

CFTR Gene Mutation of the CFTR gene disrupts the

function of the chloride channels, preventing them from regulating the flow of chloride ions and water across cell membranes. As a result cells that line the passage ways of the lungs, pancreas and other organs produce mucus that is thick and sticky

Cystic Fibrosis

Cystic Fibrosis

Assessment History of Meconium ileus at birth Foul smelling, greasy, bulky stools /

constipation Voracious appetite with poor weight gain Recurrent respiratory infections Persistent chronic cough Salty tasting skin

Diagnosis Positive sweat test – Gold standard Genetic marker

Medications Pancreatic enzymes to help digest food Inhaled antibiotics – antimicrobial for lung treatment Aerosol bronchodilators to open airways Mucolytic enzyme – to thin mucus H2 blocker – alters gastrointestinal acidic environment

Tagamet Prokinetic agents – enhances gastrointestinal motility

Reglan Vitamin C to improve absorption of other meds Vitamins E, A, D, K / fat soluble vitamins Oral and IV antibiotics – S. aureus, H. influenzae, P aeruginosa

Long Term Complications Nasal polyps Sinusitis Rectal polyps / rectal prolapse Hyperglycemia / diabetes Infertility - male

Asthma Asthma is a chronic, inflammatory lung disease

involving recurrent breathing problems. Third leading cause of hospitalization among

children younger than 15 years. Most common, chronic health problem in children

Pathophysiology Reversible changes in airway that lead to

bronchoconstriction, airway hyper-responsiveness and airway edema.

At the cellular level mast cells release histamine causing smooth muscle contraction and bronchoconstriction.

Increased mucous secretion by goblet cells causes epithelial damage

Increased mucus secretion results in airway edema, mucus hypersecretion and plugging, airway narrowing, leading to airway obstruction

Assessment Wheezing Cough Tightness of chest Prolonged expiratory phase

Assessment Hypoxemia – universal in child with moderate

to severe symptoms Hypercarbia – carbon dioxide retention from

air trapping in the alveoli and ventilation – perfusion mismatch

Monitor blood gases – PaCO2 level more than 50 mm Hg indicated ventilatory failure

Diagnostics: chest x-ray = hyper-expansion of lungs

Asthma Attack

Interdisciplinary Interventions High fowlers position / bed rest Pulse oximetry Nebulized albuterol – beta 2 agonist Chest percussion to mobilize secretions Methylprednisone / Solu-medrol IV IV fluids Oxygen to keep oxygen sats > 95%

Home Management Peak flow spirometer Identify triggers Maximize lung function Optimal physical growth Optimal psycho-social state Maximum participation

Peak Flow Meter

Peak flow meters are used to measurePEFR and are designed for monitoring purposes rather than diagnosis of asthma.

Home Medications Rescue drugs: short acting albuterol beta 2

agonist – used as a quick-relief agent for acute bronchospasm and for prevention of exercise induced bronchospasm.

Anti-inflammatory or preventative: low-dose inhaled corticosteroid: inhaled or oral prednisone

Allergy: leukotrines such as Singulair

Bronchodilators Bronchodilators rapidly relax the airway

smooth muscle cells, thus reversing the bronchospasm until anti-inflammatory effect of steroids is attained. Aerosols

Via mouth piece 3 years and older Via facial mask for less than 3 years

Corticosteroids Steroids reduce the inflammatory component

of bronchial obstruction, decrease mucus production and mediator release, as well as the late phase (cellular) inflammatory process.

Methyl prednisone IV in severe cases May need histamine H2 receptor antagonists

(cimetadine or ranitidine) if experiencing GI upset

PO prednisone – always give with food to decrease GI upset

Inhaled Corticosteroids Inhaled corticosteroids: Pulmicort, AeroBid,

Flovent Infant: mask should fit firmly to prevent cataracts Older child: rinse and spit after treatment to

prevent thrush

Family Teaching Teach how to use medication When to use and how often No OTC drugs Increase fluid intake Signs and symptoms of respiratory distress

Neonate Disorders

Pediatric Nursing January/February 1999

Bronchopulmonary Dysplasia

HistoryIt occurs in newborns who are born prematurely

and or have a variety of pulmonary disorders and who require ventilatory support with high pressure and oxygen in the first 2 weeks of life.

Pathophysiology Fibrosis of airways and marked hyperplasia of

the bronchial epithelium Increased fluid in the lungs, as a result of

disruption of the alveolar-capillary membrane Over distention due to damage to alveolar

supporting structures resulting in air trapping Fibrosis, airway edema, and broncho-

constriction

BPD Assessment Persistent respiratory distress Dependent on supplemental oxygen Failure to thrive Gastro-esophageal reflux Pulmonary hypertension

Long-term Outcomes Oxygen dependent Visual problems Feeding difficulties Developmental delay Learning difficulties

Long Term Management Supplemental oxygen CPT Bronchodilators Diuretics (pulmonary hypertension) Anti-inflammatory medication Nutritional support: po formula + NG

supplement Gastrostomy tube (GER) Bicarbonate in formula due to chronic state of

acidosis
