Severity of burn

The severity of thermal injury depend on:

A. The extent of the burned areaB. The severity of the burnC. The victim of age

D. The presence of inhalation injuries


14/22

A. The extent of the burned area

Determined by the rules of nine. The head is 9 %

Upper extremities are each 9 % The front torso is 18 % The back is 18 %

Each lower extremities is 18 % Perineum is 1 %


15/22

B. The severity of the burn

Can be described as : First degree (superficial burns)

The skin is erythematous congestedvessels in the dermis

* Second degree burns- Partial thickness burns subdivided into :

1. Superficial2. Deep


16/22

Second degree burns

1. SuperficialDestruction of the striatum granulosumand cornium with the basal layer, nottotally destroyed heals withoutscarring.

2. DeepComplete disruption of epidermis anddestruction of most basal layer


17/22

Coagulation necrosis of the epidermis anddermis with destruction of the dermalappendages scar

Third degree burns


18/22

Incinerating injuries extending deeper thanthe skin

Fourth degree burns

Electruction

Manners of death* Accident

* Suicides* Homocides

Mechanism of death

Amperage is the most important factor, currentsbetween 75 100 mA caused ventricular fibrilation. Extremelly high currents 1A/ higher

usually cause ventricular arrest. Paralysis of the muscles usually caused by low

amperage electrocution asphyxia Paralysis of the respiratory center of the brain

stemp caused by the hyperthermic effect of thecurrent (high voltage current)


21/22

Autopsy findyngs

Electrical burns, could at the point of entryor the point of exit

Accelerated onset of rigor mortis causedby the muscle contraction and depletion of

ATP Bone fracture due to generalised muscular

contraction High voltage current third degree burns Rhexiss of the heart muscle


22/22

Lightning

Death from lightning are caused by :1. High voltage direct current

cardiopulmonary arrest2. Electrotermal injuries

Pathonomonic finding for lightning

injuries is the arborrescent mark,gradually of fades within 24 hours
