What is the main problem caused by nonviable tissue in wound healing?

Nonviable tissue, also known as necrotic or devitalized tissue, presents a significant challenge in wound healing. The presence of this type of tissue can lead to an extended inflammatory phase, which is detrimental to the healing process. During this phase, the body attempts to clear away dead tissue and foreign materials, but nonviable tissue impairs this process. Instead of moving on to the next stages of healing, the wound remains in a state of inflammation, which can exacerbate the damage to nearby healthy tissue.

Furthermore, nonviable tissue can release harmful substances that not only hinder the formation of new tissue but also interfere with the overall regenerative processes. As the healthy tissue matrix degrades, the wound's size and severity can increase, making it more difficult to achieve effective closure and healing. By addressing nonviable tissue through appropriate debridement, healthcare practitioners can help facilitate the transition to a healthier healing environment, allowing the wound to progress toward closure and repair.
