what are the recommended treatments for individuals with 1st 2nd and 3rd degree burns

Burn
Treatment depends on the severity of the burn. Superficial burns may be managed with little more than simple pain medication, while major burns may require prolonged treatment in specialized burn centers. Cooling with tap water may help pain and decrease damage; however, prolonged cooling may result in low body temperature. Partial-thickness burns may require cleaning with soap and water, followed by dressings. It is not clear how to manage blisters, but it is probably reasonable to leave them intact if small and drain them if large. Full-thickness burns usually require surgical treatments, such as skin grafting. Extensive burns often require large amounts of intravenous fluid, due to capillary fluid leakage and tissue swelling.

Burn [SEP] Introduction
A burn is a type of injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or radiation (like sunburn). Most burns are due to heat from hot liquids (called scalding), solids, or fire. While rates are similar for males and females the underlying causes often differ. Among women in some areas, risk is related to use of open cooking fires or unsafe cook stoves. Among men, risk is related to the work environments. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people. Burns that affect only the superficial skin layers are known as superficial or first-degree burns.
