Frostbite

Frostbite are injuries caused by local cold exposure on tissues (n. D. Übers .: In Europe, three levels of severity.) First, they can täuschenderweise appear benign. The skin may look white or bubbly while be deaf; reheating causes significant pain. It can develop gangrene. For heavily damaged tissue can cause self-amputation. The treatment consists of warm water (40-42 ° C) and locally limited maintenance. A surgical amputation is sometimes necessary, but the decision is often guided by the results of imaging techniques, should normally be delayed until several months after the demarcation of necrotic tissue.

Frostbite usually occur in extreme cold, v. a. at high altitude, and amplified by hypothermia. The distal extremities and exposed skin are most commonly affected. Within or between tissue cells, ice crystals that lead indispensable for freezing the tissue and cause cell death form. Adjacent non-frozen zones are at risk because local vasoconstriction and thrombosis can cause endothelial ischemic damage. By reperfusion in the reheating inflammatory cytokines (z. B. thromboxanes, prostaglandins) are released, which increase the tissue damage. (N. D. Übers .: It does not come to the “freezing” in the sense of icing.) The depth of tissue loss depends on the duration and depth of frostbite.
