Efficacy and safety of single-dose ceftizoxime vs. multiple-dose cefoxitin in preventing infection after vaginal hysterectomy.

The efficacy, safety and effect of a single, 1-g dose of ceftizoxime on the return of vaginal flora were compared to those of the standard regimen of three 2-g doses of cefoxitin for prophylaxis in 99 randomized women undergoing vaginal hysterectomy. Thirty-four were studied in Dallas and 65 in Los Angeles. Surgical procedures were comparable for all the antibiotic groups, although proportionately more simple hysterectomies were performed in Dallas. The patients received a povidone-iodine vaginal preparation immediately before surgery; vaginal packs, when used, contained no antimicrobial agents. Primary prophylactic failure (operative site infection) occurred in 1 of 52 (1.9%) and 4 of 47 (8.5%) of the ceftizoxime- and cefoxitin-treated patients, respectively, for a nonsignificant difference. All five primary prophylactic failures occurred in the Los Angeles patients. One patient in each antibiotic group developed a urinary tract infection and was classified as a secondary prophylactic failure. Febrile morbidity, length of hospital stay and incidence of adverse effects did not differ by antibiotic. The enterococcus was commonly found in the postoperative vaginal flora and was of no value in predicting operative-site infection. Enterobacter species and Pseudomonas aeruginosa were isolated more commonly in patients who received cefoxitin. Diphtheroids, Staphylococcus epidermidis and Peptostreptococcus species were isolated more commonly in patients treated with ceftizoxime.(ABSTRACT TRUNCATED AT 250 WORDS)
