In a prospective randomized study 168 patients received a single dose of either cephazolin or cefotetan (1 g) as a prophylactic against wound infection after cholecystectomy. In the cephazolin group 10.3% and the cefotetan group 14.4% developed wound infections (Chi-squared = 0.34 P = less than 0.6 greater than 0.5).
