Abstract

Moxalactam was compared with cefazolin and a control group to determine the efficacy and value of a third generation cephalosporin in abdominal hysterectomy antibiotic prophylaxis. One hundred patients were prospectively randomized in a double-blind manner between moxalactam and cefazolin. An additional 50 patients who were either allergic to penicillin or refused participation in this study were simultaneously observed to establish a base line level of infection on our service during this time period. Dosage for both antibiotic groups was 1 gram given intravenously or intramuscularly on call to the operating room followed by two 1 gram doses at six and 12 hours after the first dose. Standard febrile morbidity was 36, 30 and 42 per cent for moxalactam, cefazolin and control groups, respectively. Postoperative surgical infection requiring antibiotic treatment occurred in 8, 6 and 4 per cent, respectively; urinary tract infection or symptomatic findings, or both, requiring treatment occurred in 8, 10 and 10 per cent, respectively. No pelvic abscesses occurred in this series. In every statistical evaluation of postoperative morbidity, there were no differences noted among the three groups. Our results suggest no benefit from the use of prophylactic antibiotics in abdominal hysterectomy in terms of standard febrile or infectious morbidity or urinary tract pathologic findings. In addition, there was no difference between the two antibiotic groups.
