EMERGENCY AND DISASTER NURSING TERMS USE: Trauma - Intentional or unintentional wounds/injuries on the human body from particular mechanical mechanism that exceeds the bodys ability to protect itself from injury Emergency Management - traditionally refers to care given to patients with urgent and critical needs. Triage - process of assessing patients to determine management priorities. First Aid - an immediate or emergency treatment given to a person who has been injured before complete medical and surgical treatment can be secured. BLS - level of medical care which is used for patient with illness or injury until full medical care can be given. ACLS ADVANCE CARDIAC LIFE SUPPORTSet of clinical interventions for the urgent treatment of cardiac arrest and often life threatening medical emergencies as well as the knowledge and skills to deploy those interventions. Defibrillation - Restoration of normal rhythm to the heart in ventricular or atrial fibrillation

Disaster - Any catastrophic situation in which the normal patterns of life (or ecosystems) have been disrupted and extraordinary, emergency interventions are required to save and preserve human lives and/or the environment. Mass Casualty Incident - situation in which the number of casualties exceeds the number of resources. Post Traumatic Stress Syndrome characteristic of symptoms after a psychologically stressful event was out of range of an normal human experience. EMERGENCY IT IS WHATEVER THE PATIENT OR THE FAMILY CONSIDERS IT TO BE. EMERGENCY NURSING - It is the nursing care given to patients with urgent and critical needs EMERGENCY NURSE - has a specialized education, training, and experience to gain expertise in assessing and identifying patients health care problems in crisis situations establishes priorities, monitors and continuously assesses acutely ill and injured patients, supports and attends to families, supervises allied health personnel, and teaches patients and

families within a time-limited, highpressured care environment DISASTER NURSING - a branch of emergency nursing, it refers to nursing care given to patients who are victims of disasters, whether it is manmade or natural phenomena. INCIDENT COMMAND SYSTEM - It is a management tool for organizing personnel, facilities, equipment, and communication for any emergency situation. INCIDENT COMMANDER - The head of the incident command system He must be continuously informed of all the activities and informed about any deviation from the established plan

SCOPE AND PRACTICE OF EMERGENCY NURSING The emergency nurse has had specialized education, training, and experience. The emergency nurse establishes priorities, monitors and continuously assesses acutely ill and injured patients,

supports and attends to families, supervises allied health personnel, and teaches patients and families within a time-limited, high-pressured care environment. Nursing interventions are accomplished interdependently, in consultation with or under the direction of a licensed physician. Appropriate nursing and medical interventions are anticipated based on assessment data. The emergency health care staff members work as a team in performing the highly technical, hands-on skills required to care for patients in an emergency situation. Patients in the ED have a wide variety of actual or potential problems, and their condition may change constantly. Although a patient may have several diagnosis at a given time, the focus is on the most life-threatening ones ISSUES IN EMERGENCY NURSING CARE Emergency nursing is demanding because of the diversity of conditions

and situations which are unique in the ER. Issues include legal issues, occupational health and safety risks for ED staff, and the challenge of providing holistic care in the context of a fast-paced, technologydriven environment in which serious illness and death are confronted on a daily basis. The emergency nurse must expand his or her knowledge base to encompass recognizing and treating patients and anticipate nursing care in the event of a mass casualty incident. Legal Issues Includes: Actual Consent Implied Consent Parental Consent Good Samaritan Law Gives legal protection to the rescuer who act in good faith and are not guilty of gross negligence or willful misconduct. Focus of Emergency Care Preserve or Prolong Life

Golden Rules of Emergency Care Dos - Obtain Consent - Think of the Worst - Respect Victims Modesty & Privacy Donts - let the patient see his own injury - Make any unrealistic promises Guidelines in Giving Emergency Care A Ask for help I Intervene D Do no Further Harm

Stages of Crisis 1. Anxiety and Denial encouraged to recognize and talk about their feelings. asking questions is encouraged. honest answers given

prolonged denial is not encouraged or supported 2. Remorse and Guilt verbalize their feelings 3. Anger way of handling anxiety and fear allow the anger to be ventilated 4.

V. Triage comes from the French word trier, meaning to sort process of assessing patients to determine management priorities Categories: 1. Emergent - highest priority, conditions are life threatening and need immediate attention Airway obstruction, sucking chest wound, shock, unstable chest and abdominal wounds, open fractures of long bones

Upper extremity fractures, minor burns, sprains, small lacerations without significant bleeding, behavioral disorders or psychological disturbances. 3. Non-urgent patients have episodic illness than can be addressed within 24 hours without increased morbidity Upper extremity fractures, minor burns, sprains, small lacerations without significant bleeding, behavioral disorders or psychological disturbances.

RED YELLOW GREEN BLACK

a condition when the respiration or breathing pattern of an individual stops to function, while the pulse and circulation may continue. Causes: Choking, Electrocution, strangulation, drowning and suffocation.

Field TRIAGE 1. Immediate: Injuries are life-threatening but survivable with minimal intervention. Individuals in this group can progress rapidly to expectant if treatment is delayed. 2. Delayed: Injuries are significant and require medical care, but can wait hours without threat to life or limb. Individuals in this group receive treatment only after immediate casualties are treated. 3. Minimal: Injuries are minor and treatment can be delayed hours to days. Individuals in this group should be moved away from the main triage area. 4. Expectant: Injuries are extensive and chances of survival are unlikely even with definitive care. 5. Fast-Track:

WAYS TO VENTILATE THE LUNGS 1. MOUTH-TO-MOUTH = a quick, effective way to provide O2 and ventilation to the victim. 2. MOUTH-TO-NOSE = recommended when it is impossible to ventilate through the victims mouth. (Trismus, mouth injury) 3. MOUTH-TO-NOSE and MOUTH = if the pt. is an infant 4. MOUTH-TO-STOMA = used if the pt. has a stoma; a permanent opening that connects the trachea directly to the front of the neck. For Rescue Breathing Alone: Rate is 10-12 breaths in ADULT (1.5 - 2 sec/breath) ( 1 breath every 4 to 5 secs) Rate is 20 breaths for a CHILD and INFANT (1 1.5 sec/breath) ( 1 breath every 3 secs)

Bring far arm across the casualtys chest and hold back of the casualtys hand against the nearest cheek With your other hand grasp the far thigh just above the knee, then pull the casualty towards you and on to his or her side

when the patient has spontaneous breathing when the first aider is too exhausted to continue when another first aider takes over when EMS arrives and takes over

EARLY BLS prevent brain damage, buy time for the arrival of defibrillator EARLY DEFIBRILLATION - 7-10% decrease per minute without defibrillation EARLY ACLS technique that attempts to stabilize patient

CRITERIA FOR NOT STARTING CPR - All patients in cardiac arrest receive resuscitation unless: 1. The pt. has a valid DNR order 2. The pt. has signs of irreversible death: rigor mortis, livor mortis, algor mortis, decapitation 3. No physiological benefit can be expected because the vital functions have deteriorated despite maximal therapy 4. Witholding attempts to resuscitate in the DR is appropriate for newly born infants with: - Confirmed gestation less than 23 weeks or birthweight less than 400 grams - Anencephaly When to Stop

Complete Airway Obstruction Clinical Manifestations: UNIVERSAL DISTRESS SIGNAL (patient may clutch the neck between the thumb and fingers), choking, stridor, apprehensive appearance, restlessness.

CHAIN OF SURVIVAL EARLY ACCESS early recognition of cardiac arrest, prompt activation of emergency services

CYANOSIS and LOSS of CONSCIOUSNESS develop as hypoxia worsens. MANAGEMENT FOR AIRWAY OBSTRUCTION HEIMLICH MANEUVER (Subdiaphragmatic Abdominal Thrusts) For Standing or sitting conscious patient: Stand behind the patient; wrap your arms around the patients waist Make a FIST, placing thumb side of the fist against the pts abdomen, in the midline SLIGHTLY ABOVE the UMBILICUS and WELL BELOW the XIPHOID PROCESS Make a quick INWARD and UPWARD thrust. Each thrust is separated.

Insert index finger of other hand to scrape across the back of the throat Use a hooking action

CHEST THRUST: used only in patients in advanced stages of pregnancy or in markedly obese clients a. Conscious Patient standing or sitting Stand behind the client with arms under patients axilla to encircle patients chest Place thumb side of fist on the MIDDLE of STERNUM, grasp with the other hand and perform BACKWARD thrust until foreign body is expelled. MEASURES TO ESTABLISH AIRWAY A. HEAD-TILT-CHIN-LIFT MANEUVER B. JAW-THRUST MANEUVER C. OROPAHRYNGEAL AIRWAY

a puncture or incision of the cricothyroid membrane to establish an emergency airway in certain emergency situations where endotracheal intubation or tracheostomy is not possible. indicated to pts. with trauma to head and neck, and in allergic reaction causing laryngeal edema use of gauge 11 needle or scalpel blade

Nursing Actions: Extend the neck. Place towel roll beneath the shoulders Insert the needle at a 10 to 30 degree caudal direction in the midline jest above the upper part of the cricoid cartilage Listen for air passing back and forth Direct the needle downward and posteriorly, and tape it.

For patient lying (unconscious): position patient at the back (supine); kneel astride the patients thigh Place HEEL of one HAND against the pts abdomen, place the second hand directly on the top of the fist. Make a quick UPWARD thrust FINGER SWEEP: used only in unconscious adult client Make a TONGUE-JAW LIFT. Opening the pts mouth by grasping both tongue and lower jaw between the thumb and fingers, and lifting the mandible.

D. ENDOTRACHEAL INTUBATION Indications: To establish an airway for patients cannot be adequately ventilated with an oropharyngeal airway To bypass upper airway obstruction To permit connection to ambubag or mechanical ventilator To prevent aspiration To facilitate removal of tracheobronchial secretions E. CRICOTHYROIDOTOMY

Epidural hematoma the most serious type of hematoma; forms rapidly and results from arterial bleeding forms between the dura and the skull from a tear int the meningeal area b. Subdural hematoma forms slowly and results from a venous bleed a surgical emergency c. Intracerebral hemorrhage bleeding directly into the brain matter ALERT: Assume cervical spine fracture for any patient with a significant head injury, until proven otherwise. PRIMARY ASSESSMENT: Assess for ABC SECONDARY ASSESSMENT: Change in LOC most sensitive indicator in the pts condition CUSHINGS TRIAD ( bradypnea, bradycardia, widened pulse pressure) indicating increased intracranial pressure

OTORRHEA cover it lightly with sterile gauze, dont pack it! Position head on side Maintain a supine position with bed elevated to 30 degrees

dont give narcotics or sedative assist in surgery, maintaining sterile technique

C. CERVICAL SPINE INJURIES PRIMARY ASSESSMENT: immediate immobilization of the spine A B C ( Intercoastal paralysis w/ diapragmatic breathing) SUBSEQUENT ASSESSMENT: Hypotension, bradycardia, hypothermia - suggests SPINAL SHOCK Total sensory loss and motor paralysis below the level of injury MANAGEMENT: Nasotracheal intubation initaite IV access, monitor blood gas indwelling urinary catheterization prepare to manage seizures Meds: High dose steroids and diazepam D. MAXILLOFACIAL TRAUMA PRIMARY ASSESSMENT: Immobilization of spine while performing assessment ABC (tongue swelling, bleeding, broken or missed teeth) SUBSEQUENT ASSESSMENT: Paralysis if the upward gaze indicative of INFERIOR ORBIT FX Crepitus on nose indicates nasal fracture

Flattening of the cheek and loss of sensation below the orbit indicates ZYGOMA (cheekbone) FX Malocclussion of teeth, trismus indicative of MAXILLA FX PRIMARY INTERVENTIONS: Insertion of oral airway or intubation Nasopharyngeal airway should only be used if no evidence of nasal fracture or rhinorrhea Apply bulky, loose dressing; apply ice to areas of swelling
