Input: One trial, involving 393 women undergoing either vacuum or forceps deliveries, was included. The trial compared the antibiotic intravenous cefotetan after cord clamping compared with no treatment. This trial reported only two out of the nine outcomes specified in this review. Seven women in the group given no antibiotics had endomyometritis and none in prophylactic antibiotic group, the risk reduction was 93% (risk ratio (RR) 0.07; 95% confidence interval (CI) 0.00 to 1.21; low-quality evidence). There was no difference in the length of hospital stay between the two groups (mean difference (MD) 0.09 days; 95% CI -0.23 to 0.41; low-quality evidence). Overall, the risk of bias was judged to be unclear. The quality of the evidence using GRADE was low for both endometritis and maternal length of stay. One small trial was identified reporting only two outcomes. Evidence from this single trial suggests that antibiotic prophylaxis may lead to little or no difference in endometritis or maternal length of stay. There were no data on any other outcomes to evaluate the impact of antibiotic prophylaxis after operative vaginal delivery. Future research on antibiotic prophylaxis for operative vaginal delivery is needed to conclude whether it is useful for reducing postpartum morbidity.
Output:

We searched for evidence in July 2017 and identified only one study published in 1989. The study included 393 women undergoing either vacuum or forceps delivery comparing those receiving the antibiotic cefotetan with those women who received no treatment. There were no differences between the two groups of women in terms of age, previous pregnancies and other important characteristics. The only two outcomes reported in the trial were infection of the uterus (endometritis) and length of hospital stay. The trial reported that seven women had an infection of the uterus (endometritis) in the group that did not receive any antibiotics. No woman in the antibiotic group was reported to have an infection. Giving antibiotics had no effect on length of hospital stay for the mother for either group. The quality of the evidence for these two outcomes was assessed as being low: the evidence comes from a single trial, which included a very small number of women and reported on only two outcomes. Evidence from this single trial suggests that antibiotic prophylaxis may lead to little or no difference in endometritis or maternal length of stay. There were no data on any other outcomes to evaluate the impact of antibiotics for preventing infection after operative vaginal delivery. Future research on antibiotic prophylaxis for operative vaginal delivery is needed to provide evidence on whether it is a useful intervention.
