    Abstract:
    A prospective study of women with low-risk cesarean sections was conducted in four community hospitals to determine the frequency of postoperative infections and identify factors predisposing to endometritis and wound infection. Low-risk cesarean section was defined as a scheduled procedure without an urgent indication, with any duration of ruptured membranes being less than or equal to 12 hours. In a cohort of 1863 patients, 26 (1.4%) developed endometritis and 21 (1.1%) had wound infections. Primary cesarean section was associated with endometritis in the cohort (p less than 0.01) and in a retrospective study with the same cases as in the cohort (p = 0.01). Absence of antibiotic prophylaxis was associated with endometritis (p less than or equal to 0.013) or endometritis with wound infection (p less than 0.01) in both studies. Without prophylaxis 37 such infections occurred in 957 (3.7%) women; with prophylaxis eight infections occurred in 906 (0.9%) women. Routine timely antibiotic prophylaxis in low-risk cesarean sections could lead to an annual national savings of approximately $9 million.
