||Causes and Effects
||Sunburn; steam. Reddening and peeling. Affects epidermis (top layer of skin). Heals within a week.
||Scalding; holding hot metal. Deeper burns causing blisters. Affects dermis (deep skin layer). Heals in two to three weeks.
||Fire. A full layer of skin is destroyed. Requires a doctor’s care and grafting.
||Any burns (often electrical) that completely encircle a limb or body region (such as the chest), which can impair circulation or respiration; requires a doctor’s care; fasciotomy (repair of connective tissues) is sometimes required.
||Acid, alkali. Can be neutralized with water (for up to half an hour). Doctor’s evaluation recommended.
||Destruction of muscles, nerves, circulatory system, etc., below the skin. Doctor’s evaluation and ECG monitoring required.
If more than ten percent of body surface is affected in second-and third-degree burns, shock can develop when large quantities of fluid (and its protein) are lost. When skin is burned, it cannot protect the body from airborne bacteria.
