title: Perioperative antibiotic prophylaxis for nonlaboring cesarean delivery.
abstract: OBJECTIVE
  To estimate the efficacy of antibiotic prophylaxis at the time of nonlaboring cesarean delivery in reducing postpartum infection-related complications.
  
  
  METHODS
  We performed a secondary analysis of an observational study of cesarean deliveries performed at 13 centers from 1999-2000. Patients were included if they had cesarean delivery before labor, did not have intrapartum infection, and were not given antibiotics at delivery for reasons other than prophylaxis. The occurrence of postpartum endometritis, wound infection, and other, less common infection-related complications was compared between those who did and did not receive antibiotic prophylaxis. Results were adjusted for smoking, payer status, gestational age and body mass index at delivery, race, diabetes, antepartum infections, presence of anemia, operative time, type of cesarean delivery (primary or repeat), and center.
  
  
  RESULTS
  Of the 9,432 women who met study criteria, the 6,006 (64%) who received antibiotic prophylaxis were younger, heavier at delivery, and were more likely to be African American, receive public insurance, and have diabetes. Patients who received antibiotic prophylaxis were less likely to develop postpartum endometritis (121 [2.0%] compared with 88 [2.6%], adjusted odds ratio [OR] 0.40, 95% confidence interval [CI] 0.28-0.59) or wound infection (31 [0.52%] compared with 33 [0.96%], adjusted OR 0.49, 95% CI 0.28-0.86).
  
  
  CONCLUSIONS
  Antibiotic prophylaxis at the time of nonlaboring cesarean delivery significantly reduces the risks of postpartum endometritis and wound infection.
