![]() Symptoms of Superficial Partial-Thickness Burns The following approximations can be used for adults:Īdditionally, the palm (not including the fingers or wrist area) is approximately 1% of the total surface area of the body, and can be used to approximate noncontiguous burn areas. Partial- or full-thickness burns on more than 15% of the body require immediate professional medical attention. The "rule of nines" is a method of approximation used to determine what percentage of the body is burned. Partial-thickness burns that only extend down to this layer of the skin are considered superficial.Īnother contributing factor to burn severity is how much of the body is affected. This area is composed mostly of connective tissue and serves only to strengthen the connection between the epidermis and the dermis. ![]() The dermis itself is divided into two regions, the uppermost being the papillary region. When burns extend through the epidermis and into the dermis, they are considered to be partial-thickness (second-degree) burns. For a comparison of the two classification systems, see the table below. ![]() For the sake of this article, burns will be described by thickness. However, a more precise classification system referring to the thickness or depth of the wound is now more commonly used. Traditionally, burns are characterized by degree, with first being least severe and third being most. Most burns only affect the uppermost layers of skin, but depending on the depth of the burn, underlying tissues can also be affected. Burns can vary in severity from mild to life-threatening. A burn is an injury to the tissue of the body, typically the skin.
