Prospective study of preincisional intraparietal single-dose ceftriaxone in reducing postoperative wound infection in type I and II diabetic patients.

The risk of wound contamination in diabetic patients after abdominal operations is well known. Preincisional intraparietal injection of antibiotics is used for the prophylaxis of postoperative surgical infections. Whether topically injected antibiotics remain primarily in the surgical wound or are systematically absorbed is uncertain, however.
