Burns And Scalds

Causing injuries to body tissues or skin resulting from heat is generally called burns & scalds.

Burns: Bodily injuries resulting from dry heat generated by flames, electric current, hot objects, radiation, over-exposure to sun rays & chemical corrosives, etc.

Scalds: Bodily injuries caused by hot liquids & steam etc.

Estimating The Burns & Scalds of An Adult Casualty

The area of skin surface burnt or scalded can be estimated by the ‘Rule of Nine’. Imagine the body as being 100%, so head and neck as 9%; anterior trunk as 18%; posterior truck as 18%; each upper limb as 9%; each lower limb as 18%, external genitalia as 1%. (Note: If the affected area covers only part of the skin areas, it should be assessed by palm measurement. Each palm covers 1% of the body.)

Estimating the Depth of Burn

First Degree Burn:   Swell, redness and pain on the epidermis

Second Degree Burn:    Blisters will appear in the burnt area epidermis & dermis is segregated. The casualty will    feel great pain.

Third Degree Burn:    Skin will turn charred and dark & destroy deeper layers. There is already no sense of pain.
