We have learned a lot about extended spectrum coverage of prophylactic antibiotics for cesarean section. The landmark C/SOAP trial randomized 2,013 women undergoing nonelective cesarean delivery to azithromycin 500 mg IV plus standard prophylaxis versus placebo, demonstrating a 51% reduction in the composite outcome of endometritis, wound infection, or other infection. Adjuvant Zmax (plus standard first-generation cephalosporin) is now recognized as evidence-based antibiotic coverage for intrapartum cesarean, cesarean with ruptured membranes, and patients with obesity. This last patient characteristic comes from the ERAS latest update. But what is ZMAX is not available? Is there an evidence-based peri-op alternative in these cases? Does Gent and Clinda cover mycoplasma/Ureaplasma? What about postop flagyl? Listen in for details.
