This medical exhibit depicts the progression of a post-operative septic surgical wound following abdominal surgery. The first illustration pictures the gross appearance of the wound on the female abdomen, with reactive, brown and murky infection drainage. The second illustration displays an enlarged cut-away view of the skin with the appearance of the sutured wound, progressing to infection and dehiscence, or splitting open of the sutures. It includes labels for sutures, skin, fat, fat fascia, muscle, peritoneum and the abdominal cavity. The third illustration pictures the infected material in the subcutaneous space, extending through the disrupted fascia into the abdominal cavity.
