Flashcards in Burns Deck (16):

Name the types of burns!
Remember MCAT

R Radiation
C chemical
E electrical
T thermal (MC)


D/f b/w injury to airway above larynx and below larynx

Above larynx
-Due to inhaled hot gases
-leads to laryngeal Edema would block airway

Below larynx
-Inhaled larynx
-Cast formation occur which block the main upper way


How to dx the metabolic poisoning?

Metabolic poisoning due to Hydrogen cyanide and CO dx via ABGs

T/m of both is O2


What are the warning signs of burns to the respiratory Sys?

-Hx Of being trapped in a burning room
-Burns around face and neck
-Change in voice


Important point to remember

-Vol of fluid lost is directly proportional to the area of the burn

-when size of burn is 10-15% total body surface area = Circulatory shock

-When size is >25% TBSA = fluid loss occurs in vessel remote from the burn injury


What is Abd compartment syndrome?

Caused by gut mucosal swelling, gastric stasis and peritoneal edema

-it splints the diaphragm and increases the airway pressures needed for respiration


How to calculate the area of burn?

Wallace rule of 9

Or more accurate Lund and browder chart


Rule of 9 for adults

Whole hand (palms & digits)=1% TBSA

-Perineum = 1%
-Head and Neck =1%
-Each Upper limb =9%
-Each Lower limb & Each side of torso=18%


Name the fluid used for resuscitation!

-Hypertonic saline
-Ringer lactate or Hartmann solution (MC)
-Human albumin solution OR FFP


When to start fluid resuscitation?

It should be started when :
>10% TBSA BURN In kids
>15 TBSA burn in adults


Unique feature of Hypertonic saline

Helps to prevent edema so resultant decrease in Escharomotoies and intubation


Important point to remember

Human albumin should be given after 12 hrs b/c before this time massive fluids shifts cause proteins to leak out of the cells


How to monitor fluid resuscitation?

Check urine output

-And it should be 0.5-1 ml/kg/hr and if below this level requires infusion rate to be increased by 50%


What is the t/m for circumferential full thickness burns to the limbs and chest?

-Incising the whole length of full thickness burns in the mid axial line
-Main disadvantage is blood loss so proper resuscitation needed


Name the topical agent used for deep burns (Dressing for full thickness and contaminated wounds)

-Silver sulphadiazine creams
-Silver nitrate solution

-Mafenide acetate cream
-Silver sulphadiazine & cerium nitrate


Important point

Delayed reconstruction of burn injuries is common for large full thickness burns
Viz : burn alopecia

Single/wider bands of scarring
Circumferential scarring

Hypertrophic scars
