EMERGENCY NURSINGRoberto M. Salvador Jr. RN MD

Is a specialized education, training and experience to gain expertise in assessing andidentifying patients health care problems in crisis situations.

Emergency nurse establish priorities, monitors and continuously assesses acutely illand injured patients, supports and attends to families, supervise allied health personneland teaches the patient and families within a time limited, high pressured careenvironment.

Issues in Emergency Nursing Care1. Documentation of consent.2. Limiting exposure to health risk.

Providing holistic care

a. Patient focused interventionb. Family focused intervention1. Anxiety and denial2. Remorse and guilt3. Anger4. grief

Helping family members cope Take the family members to a private place Talk to the family together Reassure the family that everything possible was done Encourage family members to support each other Encourage the family to view the body if they wish Spend time with the family members, listening to them and identifying any needs Avoid unnecessary information Care given to clients with urgent and critical needs Care must be rendered without delay

Diversified situations Consent (unless unconscious and without S.O.) Common clients (elderly, stomach pain, chest pain, fever, drug related, wound)

Disaster Nursing (terrorism)Principle: TRIAGE

Triage- a process use in sorting victims into categories of priority for care and transport based

on severity of injuries and medical emergencies.


2/38

TRIAGEFrench word trier to sortSorting of clients based on the severity of health problemsHierarchy based on the potential for life loss

Advanced skills

Principles of tactical triage1. Accomplish the greatest good for the greatest number of casualties2. Employ the most efficient use of available resources3. Return personnel to duty as soon as possible

Multiple Casualty Incident

MCI is defined as an event involving a number and/or severity of casualties,which isbeyond the capabilities of available care teams and facilities.

MINIMAL (GREEN TAG) Also known as the walking wounded Examples include but are not limited to small burns, lacerations, abrasions, and

small fractures. These casualties have minor injuries and can usually care for themselves with

self-aid or buddy aid. These casualties should still be employed for mission

requirements (e.g., scene security).

DELAYED (YELLOW TAG) The delayed category includes wounded casualties who may need surgery, but

whose general condition permits a delay in surgical treatment without undulyendangering life or limb. Medical treatment (splinting, pain control, etc.) will berequired but it can wait.

Examples include but are not limited to casualties with no evidence of shockwho have large soft tissue wounds, fractures of major bones, intra-abdominal orthoracic wounds, or burns to less than 20% of total body surface area.

IMMEDIATE (RED TAG) The immediate category includes casualties who require immediate LSI and/orsurgery. Put simply, if medical attention is not provided, the patient will die. Thekey to successful triage is to locate these individuals as quickly as possible.

Examples include but are not limited to hemodynamically unstable casualtieswith airway obstruction, chest or abdominal injuries, massive external bleeding,or shock.


9/38

EXPECTANT (BLACK TAG) Casualties in this category have wounds that are so extensive that even if they

were the sole casualty and had the benefit of optimal medical resources, theirsurvival would be highly unlikely. Even so, expectant casualties should not beneglected. They should receive comfort measures, pain medications, if possible,

and they deserve re-triage as appropriate. Examples include but are not limited to casualties with penetrating or blunthead wounds and those with absent radial pulses.

TRIAGE TAGS Triage tags are designed to communicate the triage category, treatment

rendered, and other medical information. By necessity, the information on thetag is brief. Triage tags are usually placed on the casualty by the triage officeralthough other members of the team may place or add information to the tags.

PURPOSE

To furnish the attending care provider during the evacuation of a casualty withessential information about the injury or disease and the treatment provided. The sole or initial medical record for the troops injured in combat. Each triage tag is coded with a unique sequential seven-character serial number

used for identification and tracking of the casualty. The serial number is locatedon the top right and left diagonal tear-offs.

Management:Determine the extent of injuryEstablish priority of treatmentNursing management in Sprain, Strain:1. Immobilize extremity and advise rest2. Apply cold packs initially then heat packs3. Compression bandage may be applied to relieve edema4. Assist in cast application5. Administer NSAIDS

FRACTUREA fracture is a complete or incomplete break in the continuity of bone. This will be

accompanied by varying degrees of injury to surrounding soft tissues.

CLASSIFICATION OF FRACTURESBROAD CLASSIFICATION1. Complete fractureInvolves a break across the entire cross-section of the bone & is frequently displaced

2. Incomplete fracture (usually in adults)The break occurs through only a part of the cross-section of the bone


10/38

Break in the continuity of the bone cause:DISPLACEMENT OF FRAGMENT CAUSES:DAMAGE TO THE SOFT PART CAUSES:

Clinical Features of Fractures:

1) pain and tenderness over the involved area2) loss of function3) deformity4) attitude ( shortening)5) abnormal mobility and crepitus (a grating sensation produced when bones rub each

other)6) neurovascular injury ( localized swelling & discoloration of the skin)7) radiographic findings

EMERGENCY MANAGEMENT OF FRACTURE

1. Immobilize any suspected fracture by splinting2. Support the extremity above and below when moving the affected part from a vehicle3. Suggested temporary splints- hard board, stick, rolled sheets4. Apply sling if forearm fracture is suspected or the suspected fractured arm maybebandaged to the chest5. Open fracture is managed by covering a clean/sterile gauze to prevent contamination6. DO NOT attempt to reduce ( re-align) the fracture

5 Ps in Fracture:P painP pallorP - paresthesiaP - pulselessnessP - Paralysis

Nursing ConsiderationsAssessA airwayB breathingC circulation neurogenicD disabilityE expose

always IMMOBILIZE the affected bonePrinciples of Fracture Treatment

1. Reduction of fracture2. Maintenance of alignment3. Promote callus formation4. Restoration of function5. Prevent complications

ER Management

1. Assess2. Immobilization3. A, B, C, D, E

4. Control bleeding5. TT, TIG and TAT immunization6. Wound care7. Diagnostic and Lab Procedures8. Fracture Reduction

Compartment Syndrome- a condition in which the circulation and function of tissues within a closed space are

compromised by an increased pressure within that spaceS/Sx: 4 Ps - Pain / Pallor / Paralysis / Pulselessness

* although none is pathognomonic, pain is the most important* best indicator: tissue pressure measurement

- a surgical emergency (fasciotomy)

Whitesides Technique* for measuring intracompartmental pressure

* results in permanent neurovascular damage if not relieved in 4 to 6 hrs.* the normal tissue pressure within closed compartments is approximately 0 mmHg

> pressures of within 10 to 30mmHg of a patients diastolic blood pressure - therewill be inadequate tissue perfusion and relative ischemia

> if the pressure within a compartment equals or exceeds the patients diastolicblood pressure - there will be no effective tissue perfusion

Compartment syndromeASSESSMENT FINDINGS1. Pain- Deep, throbbing and UNRELIEVED by opioidsPain is due to reduction in the size of the muscle compartment by tight castPain is due to increased mass in the compartment by edema, swelling or hemorrhage2. Paresthesia- burning or tingling sensation3. Numbness4. Motor weakness5. Pulselessness, impaired capillary refill time and cyanotic skin6. Edema unrelieved by elevation

Compartment syndromeMedical and Nursing management1. Assess frequently the neurovascular status of the casted extremity2. Elevate the extremity above the level of the heart


12/38

3. Assist in cast removal and FASCIOTOMY

Fat EmbolismOccurs usually in fractures of the long bonesFat globules may move into the blood stream because the marrow pressure is greater

than capillary pressureFat globules occlude the small blood vessels of the lungs, brain kidneys and otherorgans

Onset of s/sx of fat embolism is rapid, (within 24-72 hours)

ASSESSMENT FINDINGS1. Sudden dyspnea and respiratory distress2. tachycardia3. Chest pain4. Crackles, wheezes and cough

5. Petechial rashes over the chest, axilla and hard palate

Nursing ManagementSupport the respiratory function

Respiratory failure is the most common cause of deathAdminister O2 in high concentrationPrepare for possible intubation and ventilator support

Mafenide acetate- Gram (-) and (+)-diffuses rapidly to eschar

Nursing Management1. Emergent phase (time of injury)Remove person from source of burn.1) Thermal: smother burn beginning with the head.2) Smoke inhalation: ensure patent airway.


25/38

3) Chemical: remove clothing that contains chemical; lavage area with copious amountsof water.4) Electrical: note victim position, identify entry/exit routes, maintain airway.

Nursing Management

1. Emergent phase (time of injury)Cool the burn for several minutes. DONT USE ICE!!Wrap in dry, clean sheet or blanket to prevent further contamination of wound andprovide warmth and conserve body heat.

Assess how and when burn occurred.

Nursing Management1. Emergent phase (time of injury)Remove constricting clothes and jewelryCover the wound with a sterile dressing or clean, dry clothProvide IV route only if possible

GENERAL NURSING INTERVENTIONS IN THE HOSPITAL1. Provide relief/control of pain.a. Administer morphine sulfate IV and monitor vital signs closely.b. Administer analgesics/narcotics 30 minutes before wound care.c. Position burned areas in proper alignment

GENERAL NURSING INTERVENTIONS IN THE HOSPITAL2. Monitor alterations in fluid and electrolyte balance.a. Assess for fluid shifts and electrolyte alterationsb. Monitor Foley catheter output hourly (30 cc per hour desired).c. Weigh daily.d. Monitor circulation status regularly.e. Administer/monitor crystlloids/colloids

GENERAL NURSING INTERVENTIONS IN THE HOSPITAL3. Promote maximal nutritional status.a. Monitor tube feedings if Peripheral Nutrition is ordered.


26/38

NPO immediately after injury!!! ONLY when oral intake permitted, provide high-calorie,high-protein, high- carbohydrate diet with vitamin and mineral supplements .c. Serve small portions.d. Schedule wound care and other treatments at least 1 hour before meals.GENERAL NURSING INTERVENTIONS IN THE HOSPITAL

4. Prevent wound infection.a. Place client in controlled sterile environment.b. Use hydrotherapy for no more than 30 minutes to prevent electrolyte loss.Observe wound for separation of eschar and cellulitis.GENERAL NURSING INTERVENTIONS IN THE HOSPITAL5. Prevent GI complications.a. Assess for signs and symptoms of paralytic ileus.b. Assist with insertion of NG tube to prevent/control Curlings/stress ulcer; monitorpatency/drainage.GENERAL NURSING INTERVENTIONS IN THE HOSPITAL5. Prevent GI complications.

c. Administer prophylactic antacids through NG tube and/or IV cimetidine (Tagamet) orranitidine (Zantac) (to prevent stress ulcer).d. Monitor bowel sounds.e. Test stools for occult blood.

RehabilitationMethods of coping and re-socializationEnsure optimum nutritionInitiate physical therapy to regain and maintain optimal range of motion and achievewound coverageProvide psychosocial support to promote mental health

RehabilitationProvide family-centered care to promote integrity of the family as a unitEncourage post-discharge follow-up for several yearsEnsure appropriate referral to cosmetic surgeon, psychiatrist, occupational therapist,nutritionist and physical therapist

Drugs for BurnsMafenide (Sulfamylon)1) Administer analgesics 30 minutes before application.2) Monitor acid-base status and renal function studies. SIDE EFFECT: LACTIC

ACIDOSIS3) Provide daily BATH for removal of previously applied cream.

Drugs for BurnsSilver sulfadiazine (Silvadene)1) Administer analgesics 30 minutes before application.2) Observe for and report hypersensitivity reactions (rash, itching)3) Store drug away from heat


27/38

4) Disadvantage: poor eschar penetration

Drugs for BurnsSilver nitrate1) Handle carefully; solution leaves a gray or black stain on skin, clothing, and utensils.

2) Administer analgesic before application.3) Keep dressings wet with solution; dryness increases the concentration and causesprecipitation of silver salts in the wound.

Drugs for BurnsPovidone-iodine (Betadine)

Administer analgesics before application.Assess for metabolic acidosis/renal function

Gentamicin

Assess vestibular/auditory and renal functions at regular intervals.

CimetidineGiven to prevent Curlings ulcerWound debridement (ESCHAROTOMY)

Heterografts from animalsBiosynthetic biobraneDermal substitute integra, allodermSkin Grafting

Donts in burnsDO NOT apply ointment, butter, ice, medications, fluffy cotton dressing, adhesivebandages, cream, oil spray, or any household remedy to a burn. This can interfere withproper healing.DO NOT allow the burn to become contaminated. Avoid breathing or coughing on theburned area.DO NOT disturb blisters or dead skin.DO NOT apply cold compresses and DO NOT immerse a severe burn in cold water.This can cause shock.DO NOT place a pillow under the victim's head if there is an airway burn and they arelying down. This can close the airway.

NURSING MANAGEMENT


38/38

1. Administer prescribed medicationsNitrates- to dilate the coronary arteries

Aspirin- to prevent thrombus formationBeta-blockers- to reduce BP and HRCalcium-channel blockers- to dilate coronary artery and reduce vasospasm

Basic Life SupportThis is a strategy which aims to improve the outcome for victims of Cardiopulmonaryarrest and is now being adopted internationallyIt involves a series of events which are interconnected to each other like the links of achain

HOW DOES CPR WORK?All the living cells of our body need a steady supply of oxygen to keep us aliveCPR works because you can breathe air into the victims lungs to provide oxygen intothe blood. Then, when you press on the chest, you move oxygen-carrying blood throughthe body.

WHEN WILL YOU DO CPR?CPR must be started as soon as possible when the carotid pulse is not appreciated or

if breathing either stops or ineffective.In case of doubt, do CPR. Any delay in starting CPR reduces the chances of survival.

In addition, the brain cells begin to die after four to six minutes without oxygen.
