BACKGROUND:Reduction mammaplasty is a well-established procedure. Studies have shown benefits of using antibiotics in this procedure. Nevertheless, there is no solid evidence to support postoperative antibiotic prophylaxis. The authors evaluated the influence of postoperative antibiotic delivery on infection rates after reduction mammaplasty. METHODS: The authors conducted a randomized trial of noninferiority, with two parallel groups, with triple blinding. The participants were 124 women with breast hypertrophy, with reduction mammaplasty already scheduled, selected consecutively. All patients underwent reduction mammaplasty, performed by the same surgical team, using the superomedial pedicle technique for ascending the nipple-areola complex. All patients received cephalothin (1 g) intravenously at the anesthetic induction and every 6 hours for 24 hours. At hospital discharge, they were assigned randomly to either the placebo (n = 62) or antibiotic group (n = 62) and were instructed to take identical capsules containing 500 mg of cephalexin or placebo, respectively, every 6 hours, for 7 days. Patients were assessed weekly, for 4 weeks, regarding the occurrence of surgical-site infection, by a surgeon who was unaware of the allocation. The criteria and definitions of the Centers for Disease Control and Prevention were adopted. RESULTS: There was no statistical difference between groups regarding age, body mass index, or resected breast tissue weight. The overall surgical-site infection rate was 0.81 percent. Only one patient, allocated to the antibiotic, presented infection, classified as superficial incisional (p = 1.00). In the placebo group, surgery time was higher (p = 0.003). CONCLUSION: The maintenance of antibiotics in the postoperative period of reduction mammaplasty did not influence the rates of surgical-site infection. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.
