Role of prophylactic antibiotics in open and basilar fractures of the skull: a randomized study.

Abstract

The aim of this study was to investigate the controversial issue of the use of prophylactic antibiotics in open and basilar fractures of the skull. A series of 157 patients were randomized to receive no antibiotics (group A = 46 patients) or ceftriaxone for 3 days (group B = 50 patients), or the combination ampicillin/sulphadiazine for 3 days (group C = 61 patients). The incidence of meningitis was similar in both the antibiotic and non-antibiotic groups. However, the overall incidence of infectious complications in the non-antibiotic group was significantly higher than in the antibiotic group (8.7 per cent vs 0.9 per cent, P < 0.05). There was no significant difference between the ceftriaxone group and the ampicillin/sulphadiazine group. The results of the study suggest that antibiotic prophylaxis has a role in the management of open and basilar fractures.
