Post operatively a patient started with clinical image of necrotizing fasciitis like erythema, tenderness, blisters, and skin necrosis. Microbiological examination of the cultures unraveled that Acinetobacter species sensitive to meropenem. The patient was taken to the operation room for the fasciotomy and subsequently debridement of the wound was done to deal with the sepsis.
