What does necrotic tissue signify in relation to healing?

Necrotic tissue signifies dead tissue that hinders the healing process. When tissue becomes necrotic, it indicates that it has lost its blood supply and is no longer viable. This dead tissue can impede the body's natural healing mechanisms, as it serves as a barrier to new tissue formation and may increase the risk of infection. In wound care, the presence of necrotic tissue often necessitates debridement, which is the removal of this non-viable tissue to promote a healthier environment for healing and to enhance the repair of surrounding tissues. While healing involves various stages and the presence of healthy tissue is crucial for recovery, necrotic tissue must be addressed before effective healing can occur.
