The effect of the timing of antibiotics and surgical treatment on infection rates in open long-bone fractures: A 9-year prospective study from a district general hospital

Aims: To determine whether a delay of greater than 6 h from injury to initial surgical debridement and the timing of antibiotic administration affect infection rates in open long-bone fractures. Methods: We studied 248 consecutive open tong-bone fractures in 237 patients over a 9-year period. The patients were followed until clinical or radiological union occurred or until a secondary procedure for non-union or infection was performed. Results: Surgical debridement was performed within 6 h of injury in 62% of cases and after 6 In in 38% of cases. Infection rates were 7.8% and 9.6%, respectively, and the difference was not statistically significant (p = 0.6438). The timing of antibiotic administration was not significantly related to the infection rate. Conclusion: Whilst open tong-bone fractures should be treated expeditiously, we suggest that adherence to a 6 h window has not been shown to affect infection rates nor has the timing of antibiotic administration during the acute phase.
