Final answer:
Successful enzymatic debridement in deep partial-thickness wounds is indicated by the separation of eschar, as it signifies the removal of necrotic tissue and the promotion of wound healing.
Step-by-step explanation:
When assessing the efficacy of enzymatic debridement in a patient with deep partial-thickness wounds, the indication of successful wound care treatment is the separation of eschar. Enzymatic debridement works by breaking down necrotic tissue, facilitating its removal and the subsequent wound healing process. The presence of a gray wound bed, development of new eschar, or presence of purulent exudate are typically not desirable outcomes and may indicate infection or a need for a change in treatment strategy.
