How is skin necrosis treated?

Intuitively areas of extensive necrosis should be treated with surgical debridement, to promote healing of the wound and to reduce the risk of secondary infection. However, extensive debridement may cause release of cytokines that may further exacerbate any difficulties with vital organ function.
