Problem:
A patient was admitted with severe stage 3 pressure ulcer on the left buttock with extensive necrotic tissue and gangrene. She was taken to the Operating Room where the surgeon carefully excised the necrotic tissue. The patient was returned to the nursing unit where the wound was monitored carefully and additional antibiotic treatment was administered. By the fourth day the wound was beginning to close but treatment was continued. On the 7th day, the family was advised to use an egg crate mattress and to turn the patient regularly.
