Why is necrotic tissue a concern in wound healing?

Necrotic tissue is a concern in wound healing primarily because it can impede the healing process and significantly increase the risk of infection. When tissue becomes necrotic, it indicates that it is dead or dying, often unable to support the regenerative processes required for healing. This dead tissue can harbor bacteria and other pathogens, which can lead to infection. Additionally, necrotic tissue serves as a physical barrier to the migration of healthy cells necessary for wound closure and healing.

In a healing environment, the presence of healthy granulation tissue is essential for optimal recovery. Necrotic tissue does not contribute to this process and may even delay it, necessitating more extensive interventions, such as debridement, to remove the dead tissue. Therefore, prompt and appropriate management of necrotic tissue is essential to promote proper wound healing and minimize complications.
