What does "eschar" refer to in the context of burn injuries?

In the context of burn injuries, "eschar" specifically refers to the dead, necrotic tissue that forms over a full-thickness burn. This tissue is a result of the severe damage caused by the burn, which leads to cell death in the affected area. Eschar acts as a protective barrier but inhibits the healing process since it can prevent healthy tissue from regenerating. Understanding eschar is vital in burn management, as it helps healthcare providers evaluate the depth of the burn and determine the appropriate treatment.

Being aware of eschar's significance can guide nursing interventions, such as debridement, to remove the necrotic tissue and allow for proper healing. Recognizing this distinction can enhance patient care by ensuring interventions are timely and appropriate for the burn's severity. Additionally, it sets apart the concept from other options like fluid in blisters or surrounding healthy skin, which are relevant but pertain to different aspects of burn pathology.
