PURPOSE: To evaluate the susceptibility of microorganism causing early infection in open fractures to current antibiotic prophylaxis and determine contributing factors towards development of resistance. METHODS: A total of 110 cases of open fractures were selected in this study. They underwent routine debridement and C&S were followed up. Risk factors to antibiotic resistance were identified. RESULTS: Admission to ICU, blood transfusion, antibiotic regime and duration, fracture grade, injury severity score and duration of admission were significantly associated with resistance of microorganism. There was Gram-negative predominance of 65.9%. The overall resistance to Cefuroxime was 68.6% and 36.9% to Gentamicin. Staphyloccoccus aureus and MRSA were the commonest Gram-positive while Pseudomonas and Acinetobacter Gram-negative. DISCUSSIONS: Resistance in open fracture is not well established unlike rate of infection. Previous studies reported predominant Gram-postive microorganisms which form the basis of prophylactic antibiotics1 . Hannigan et al. reported increasing multi-drug resistance bacterias in open fractures2 . Carsenti-Etesse et al. reported resistance was influenced by type and duration of antibiotics while others have described various other factors3 . CONCLUSION: The high resistance of microorganisms and shift to predominantly Gram-negative microorganisms is alarming. Further measures are needed to achieve optimal outcome. REFERENCES: 1.
