Document Summary
Burn is a coagulation necrosis of tissue due to thermal or chemical injury. It is mostly seen in developing countries where there is overcrowding, poor housing designs and wide spread usage of open fire for cooking. Women and children are affected most as majority of the burns occur at home. Types of burns, according to the mechanism, include: The severity of a burn injury is a function of the burn depth (degree) and the extent or percentage of the body surface that is burned. Determining the percentage of burn surface is important to calculate the amount of fluid requirement while determination of burn depth is important for burn wound management. 1- first degree burn: it involves the epidermis only and manifests with erythema. 2- second degree (partial thickness) burn: this involves part of dermis. It manifests with blisters, edema, moist surface and pain at the affected site. 3- third degree (full thickness) burn: involves complete burn of the dermis.
