Controlled trial of cephradine versus cefuroxime in vascular surgery.

Two hundred and three consecutive patients undergoing acute or elective vascular reconstructions (N = 162) or amputations (N = 41) were randomized to receive either a single dose of cephradine 2 g intravenously or cefuroxime 1.5 g intravenously at induction of anaesthesia. Infective morbidity in both groups was assessed post-operatively as was therapeutic antibiotic prescribing. No significant differences in septic complications were found between patients receiving cefuroxime or cephradine. In addition, tissue penetration of each antibiotic was assessed by assay of serum and tissue specimens. Serum levels of cefuroxime were significantly less than cephradine 10 min after injection (median concentrations 115 micrograms/ml versus 182 micrograms/ml, p less than 0.01 Wilcoxon), but there were no differences in tissue penetration.
