✦ Synopsis


Background:

Although appropriate perioperative antibiotic prophylaxis has significantly reduced wound infection rates in clean-contaminated head and neck surgical procedures, controversy still remains regarding the optimal antibiotic regimen.

Methods:

In this prospective, double-blind clinical trial, 159 patients were randomized to receive amoxicillin-clavulanate, clindamycin plus gentamicin, or cefazolin intravenously up to 1/2 hour before surgery and at 6-hour intervals for an additional three doses.

Results:

An overall wound infection rate of 23% was observed. thirteen (22.8%) infections occurred in the amoxicillin-clavulanate-treated group, 11 (21.2%) in the clindamycin plus gentamicin-treated group, and 13 (26%) in the cefazolin-treated group, which was not statistically significant. only prior medical illnesses, such as chronic obstructive pulmonary disease and diabetes mellitus, correlated with an increased wound infection rate (p = 0.018).

Conclusions:

Amoxicillin-clavulanate, clindamycin plus gentamicin, and cefazolin seem to have similar efficacy when administered prophylactically in clean-contaminated head and neck surgical procedures.
