What is a potential risk associated with necrotic tissue in a wound?

Necrotic tissue poses a significant risk in wound healing primarily because it serves as a breeding ground for bacteria. This tissue is non-viable and can harbor pathogens, increasing the likelihood of infection. When necrosis is present, it interrupts the normal healing process as the body must first remove this dead tissue before it can effectively regenerate healthy skin and underlying structures. Furthermore, necrotic tissue can create a barrier that hinders the penetration of essential nutrients and oxygen to the wound site, both of which are crucial for proper healing. Therefore, the presence of necrotic tissue is detrimental and can lead to complications, including delayed healing and increased opportunities for infection.
