Cefonicid versus clindamycin prophylaxis for head and neck surgery in a randomized, double-blind trial, with pharmacokinetic implications.

Perioperative single-dose antibiotic prophylaxis of cefonicid was compared with clindamycin in a prospective, randomized, double-blind trial of patients undergoing oncologic head and neck surgery. Antibiotics were administered intravenously beginning 1 to 2 h preoperatively. Cefonicid, 1 g, was given as a single dose. Clindamycin, 600 mg, was administered every 8 h for a total of four doses. Blood and wound drainage samples were collected for 24 h following the dose of cefonicid and assayed for total and free cefonicid concentrations, using reverse-phase high-performance liquid chromatography. Although total concentrations of cefonicid in both serum and wound drainage exceeded the MIC for 90% of the isolates of common bacterial pathogens for 24 h, free concentrations in serum and wound drainage (11.0 and 14.9% of total concentrations) were subinhibitory within 6 h following administration. Free concentrations of cefonicid in the postoperative wound drainage were subinhibitory for the entire study period, both perioperatively and postoperatively. Postoperative wound infection occurred significantly (P less than 0.05) more frequently in patients receiving cefonicid (24%) as compared with those receiving clindamycin (8.2%). The relatively low free levels of cefonicid achieved in serum and wound drainage were attributed to the high degree of protein binding (89% in serum) and may be related to the poor clinical outcome.[1]
