Emergency Burn Management Flashcards
Emergency Burn Management
Focus is to save life, minimize disability, & prepare for definitive care
Emergency Healthcare Professionals
- Remove all rings, watches, & jewelry
- Obtain large bore IV access
- Obtain hx of injury
Respiratory Management
-
Circumferential, full-thickness burns to chest wall can lead to restriction of chest wall expansion & dcrd compliance
> dcrd lung compliance requires higher vent pressures to provide adequate tidal vols
> non-intubated pt: CMs of chest wall restriction include rapid, shallow resps; poor chest wall excursion; and severe agitation
> intubated pt: incring peak airway pressure values - ABGs: incrd PaCO2
- Escharotomy
Escharotomy
- Burn eschar incisions
- May be needed immediately to incr compliance & for improved ventilation
- Usually made bilaterally along anterior axillary lines and are connected by a transverse incision at costal margin
Circulatory Management
- Focus on fluid resusitation
-
Parkland Formula
> 1st 8hrs: 50% of calculated amnt admind
> 2nd 8hrs (9-16): 25% is given
> 3rd 3hrs (17-24): 25% is given -
Rate of fluid admind is adjusted according to response
> monitor urine output, HR, BP, LOC
> document I/Os
Underresuscitation
May result in inadequate cardiac output, leading to inadequate organ perfusion and potential for wound conversion from partial-thickness to full-thickness
end-organ perfusion issues
Overresuscitation
May lead to modersate to severe pulm edema, to escessive wound edema causing a dcr in perfusion of unburned tissue in distal portions of extrems. or to edema inhibiting perfusion of the zone of stasis resulting in wound conversion
Pathophysiology of Burn Shock
- Pt may present in shock r/t intravascular vol loss, dcrd tissue perfusion
- This occurs as a result of firect injury to capillaries and release of vasoactive substances
- The capillaries become more permeable, and proteins move out of the intravascular spaces into interstitium; hypovolemia & edema result
> once hypovolemic state affects EOP; shock state
Rate of Fluid Loss from Intravascular Spaces Depends on
- Age
- Burn size & depth
- Intravascular pressures
- Time elapsed since burn injury
Burn Shock - Hemodynamic Alterations
-
Dcrd myocardial contractility & dcrd CO despite adequate vol resuscitation
> dcrd preload -
Incrd systemic vascular resistance (SVR), and incrd pulm vascular resistance (PVR)
> incrd PVR can lead to pulm edema - these are compensatory mechanisms
Emergency Management - Kidney Management
-
If fluid resuscitation is inadequate, AKI may occur
> can progress to failure - Indwelling urinary catheter may be placed to monitor the effectiveness of fluid resuscitation
- A catheter may be necessary if the burn extends into the perineal area bc of the presence or development of edema
Emergency Management - GI System Management
-
NG or OG tube
> to prevent abdominal distention, emesis, & potential aspiration - Prophylaxis w/ histamine blockers or sucralfate is initiated bc pts w/ burns are prone to ileus
-
Enteral nutrition
> should be promptly initiated for pts w/ burns via nasoduodenal or nasojejunal tube
Emergency Management - Extremity Pulse Assessment
-
Edema formation may cause neurovascular compromise to the extremities; frequent assessments are necessary to evaluate pulses, skin color, capillary refill & sensation
> arterial circulation is at greatest risk w/ circumferential burns if not corrected, reduced arterial flow causes ischemia & necrosis
> doppler flow probe
> an escharotomy may be required to restore arterial circulation and to allow for further swelling
Emergency Management - Laboratory Assessment
-
Initial lab studiese include complete blood count, electrolytes, BUN, creatinine, urinalysis, glucose, & blood screening
> inhalation injury warrants arterial blood gas measurements, HbCO lvl determination, cultures, alcohol & drug screens, & cyanide lvls
> a baseline nutrition status: albumin
> burns: creatine kinase, urinalysis, & urine myoglobin are good indicators of rhabdo
> serum lactate: inflamm marker indicating burn severity
> an ECG is obtained for all pts w/ electrical burns or preexisting heart disease
Emergency Management - Wound Care
-
After wounds have been assessed, topical antimicrobial therapy IS NOT a priority during emergency care
> wounds must be covered w/ clean, dry dressungs or sheets
> measures to prevent hypothermia
> tetanus prophylaxis
