Antibiotic prophylaxis with two doses of cephalosporin in patients managed with internal fixation for a fracture of the hip.

A prospective, randomized, double-blind study was performed to evaluate the effects of antibiotic prophylaxis on the development of a wound infection in 239 patients who had immediate stabilization of a fracture of the proximal part of the femur with a dynamic hip screw. The effects of two perioperative doses of cefotiam, given twelve hours apart, were compared with those of two doses of a placebo. Sixteen perioperative risk factors were evaluated to determine whether it was possible to identify patients who were at risk for a wound infection. All patients were followed for a minimum of six weeks. Antibiotic prophylaxis significantly reduced the prevalence of wound infection (p < 0.05): the rate of major wound infection decreased from 5 to 1 per cent and the rate of minor wound infection, from 11 to 4 per cent. The most powerful predictors of major wound infection were the duration of the operation, the interval between the accident and admission to the hospital, and the duration of postoperative urinary catheterization. The preoperative level of serum albumin and the absolute lymphocyte count were significant predictors (p < 0.05) of minor wound infection and systemic infection, respectively.
