T31: Burns classified according to extent of body surface involved

T31.9: Burns involving 90% or more of body surface

Burns involving 90% or more of body surface, as indicated by the ICD-10 classification T31.9, are serious injuries often caused by exposure to high heat or flames, scalding liquids, and certain dangerous chemicals. These burns can affect not only the skin, but also the underlying tissues, including nerve endings, blood vessels, muscles or even bone. Common symptoms include intense pain, redness, blistering, skin that appears white or charred, and swelling. More significant burns can also result in shock due to substantial fluid loss, which may present as confusion, weakness and rapid heart rate. This kind of burn is considered life-threatening due to the extensive damage it causes and the high risk of secondary complications including dehydration, infection, and dysfunction of crucial bodily systems like respiratory or circulatory systems. Depending on its severity, the progression of the condition varies and might result in long term physiological and psychological impact.
