What does the term gangrene refer to?

The term gangrene specifically refers to the death of tissue, which can occur due to a variety of reasons, such as lack of blood flow (ischemia), infection, or severe injury. When tissue dies, it can lead to a serious medical condition that may require surgical intervention, such as amputation, especially if it progresses beyond a certain point. The underlying causes often involve problems with circulation or the presence of bacteria that contribute to tissue necrosis. Understanding gangrene is crucial in wilderness medicine as it emphasizes the importance of timely assessment and treatment of injuries to prevent complications like tissue death.
