Non-freezing cold injuries (NFCI) is a class of tissue damage caused by sustained exposure to low temperature without actual freezing. [1] There are several forms of NFCI, and the common names may refer to the circumstances in which they commonly occur or were first described, such as trench foot, which was named after its association with trench warfare.
Cold injury (or cold weather injury) is damage to the body from cold exposure, including hypothermia and several skin injuries. [6] Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. [5] Freezing cold injuries involve tissue damage when exposed to temperatures below freezing (less than 0 degrees Celsius).
Trench foot occurs due to prolonged exposure of the feet to cold, damp, and often unsanitary conditions. [1] Unlike frostbite, trench foot usually occurs at temperatures above freezing, [1] and can be classed as a form of non-freezing cold injury. [3] Onset can be as rapid as 10 hours. [1] Risk factors include overly tight boots and not moving. [4]
The process of frostbite differs from the process of non-freezing cold injury (NFCI). In NFCI, temperature in the tissue decreases gradually. This slower temperature decrease allows the body to try to compensate through alternating cycles of closing and opening blood vessels (vasoconstriction and vasodilation).
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy can be used in many ways, including whole body exposure for therapeutic health benefits or may be used locally to treat a variety of tissue lesions .
