Although cephalosporins and penicillins have a beta-lactam chemical structure, the forms are sufficiently different to allow cephalosporin use in some with a penicillin allergy. Studies (including a single-center randomized trial) suggest that azithromycin-based extended-spectrum prophylaxis a single dose of azithromycin plus standard cephalosporin prophylaxis may result in a lower risk of infection after cesarean section than standard prophylaxis alone.15 It has been thought that the efficacy of such prophylaxis was due to coverage for ureaplasma species, which are commonly associated with infections after cesarean section.16-21 We performed this study to assess whether the addition of azithromycin to standard antibiotic prophylaxis before skin incision would reduce the incidence of infection after cesarean section without increasing the risk of other adverse maternal and perinatal outcomes.
