Background

BURN WOUND DEGREES

1st

    -red, tender, no blisters
    -two point discrimination intact
    -heals without scarring

2nd (partial thickness)

    superficial
         -thin blisters
         -heals without scarring in 2- 3 wks.
    deep
         -thick blisters
         -two point discrimination decreased
         -can feel pressure
         -potential for scar/contractions

3rd (full thickness)

    -skin white, leathery and anesthetic
    -always needs grafting.

4th

    -3rd degree + involves muscle, bone, or other deep structures


Rule of Nines

ADULTS

Each area is 9% BSA:

-Entire head and neck

-Each arm including hand

-Chest

-Abd

-Upper back

-Lower back

-Each front of leg

-Each back of leg

1%

-Genital region


CHILDREN

Each area is 9% BSA:

-Anterior head and neck

-Posterior head an neck

-Each arm including hand

-Chest

-Upper back

-Lower back

13.5%:

-Each leg (not broken up to front or back)

1%:

-Genital Region

Rule of Palms

-Pt's palm ~1%

-Use to estimate scatter burns

-Also use for local burns up to 10% BSA


Pre-Hospital

1) Assess for sings of inhalational injury

-Start humidified O2

-Intubation if necessary (below)

2) IVF (below)

3) Remove all burned/burning clothing, jewelry

4) Immerse wounds in cold water (1-5˚C)

-Only effective within first 30 mins)

-No direct ICE to wound


ED W/U

1) Basic labs

2) CO level

3) CN level if suspicious and/or empiric Tx (see below)

4) Work-up for associated trauma, if indicated


Management

1) Airway (Intubation below)

2) IVF (below)

3) Foley cath

4) Dress (saline/tap/petroleum gauze)

6) No IV Abx

7) Escharotomy (below)

8) H2 blocker (stress ulcer)

9) NG tube (gastroparesis)

10) No PPx abx; topical bacitracin OK

11) Td

12) Analgesia

13) Consider Transfer



I. INTUBATION GUIDELINES

1. Usual criteria

2. Hard signs

    -stridor
    -hoarseness
    -pharyngeal burns

3. Any 3 Soft Signs

    -H/O unconciousness
    -Noxious fumes at scene
    -Burn occuring in closed space
    -Facial burns
    -Carbonaceous sputum
    -CO level >15%

4. Additional

    -Need for large amnt analgesics
    -Transfer w/ potential decomp


II. FLUID RESUSITATION

If:

1) >20% BSA (2nd&3rd)

2) Evidence of shock

Total Fluids = Parkland + maint + blood loss

Parkland:

4 x kg x %BSA (2nd&3rd) = cc NS (or LR)

Give 1/2 in first 8hrs, remainder in next 16hrs

  • From time of inital injury


Place Foley cath:

Goal =

Adult: UOP >30mL/hr

Peds: UOP >1mL/kg/hr

  • CVP line indicated if h/o cardiopulmonary dz


IX. CYANIDE

Consider empiric tx for smoke inhalation victims with (any):

1) Hypotension

2) Metabolic acidosis

3) CV collapse

  • Give sodium thiosulfate (12.5 mg) alone (given possiblility of CO also)
    • See also Tox: Cyanide/Sulfide


X. ESCHAROTOMY

1. Restriced ventilation

    -Anterior axillary line
    -2cm below clavicle to 10th rib
    -May connect (square)

2. Restricted perfusion (focal)

    -along long axis of hands, forearms, feet, fingers, toes if no pulse by doppler
    -Lateral on extremity
    -No perfusion, add medial
    *Bovie or scalpel


Disposition

TRANSFER CRITERIA (ABA 1994)

1. 2-3 deg >10% in pt <10 or >50yo

2. 2-3 deg >20% anyone

3. 3 deg >5% anyone

4. Complicating factors

    -Sig face/hand/feet/perineum/major joint
    -Circumferential burns
    -Inhalation injury
    -Concomitant trauma
    -Sig pre-existing dz
    -Sig electrical/chemical burn
  • For moderate burns not meeting transfer criteria may admit
