title: [Infection prophylaxis in open leg fractures. Comparison of a dose of pefloxacin and 5 days of cefazolin-oxacillin. A randomized study of 616 cases].
abstract: OBJECTIVE
  Was to compare the efficacy of a single 800 mg injection of Pefloxacin (PF) versus 2 days of cefazolin (1 gr.Q.6 H) followed by 3 days of oxacillin (1 gr.Q.8 H) in patients with an open tibial fracture and to examine the predictive factors for infection. A double-blind double dummy, multicentric, randomized trial was performed. 616 adults with an open tibial fracture requiring single-stage bone coverage were included. The end point was wound infection within 3 months.
  
  
  RESULTS
  Within 3 months, 21/316 patients were infected in the PF group (6.6 p. 100) versus 24/300 in the CZ-OX group (8 p. 100), the difference was not significant (95 p. 100 Cl for difference: -4.8 p. 100 to 2.1 p. 100). Twenty one strains were isolated in 18 infected patients in the PF group, and 27 in 20 patients in the CZ-OX group. Negative gram bacteria were less frequent in the PF group (10 p. 100) than in the CZ-OX group (48 p. 100), and positive gram bacteria were more frequent in the PF group (90 p. 100) than in the CZ-OX group (52 p. 100). Independent risk factors for infection were severe contamination, widespread contusion, unstable fracture, positive sample in the emergency room and at the end of surgery. Resistant infecting bacteria rate was 24 p. 100 in infected cases.
  
  
  CONCLUSIONS
  There was no difference in infection rates after surgery for open tibial fractures between a 800 mg injection of Pefloxacin and 2 days of pephazolin followed by 3 days of oxacillin. Infecting bacteria were mainly nosocomially acquired.
