RESUMO
This prospective study was conducted to assess the influence of antibiotics use on surgical site infections (SSI) rates after reduction mammaplasty. Patients undergoing reduction mammaplasty were assigned to group 1 (n = 50), which received intravenous cephalotin pre- and postoperatively, besides oral cephalexin for 6 days after discharge, or to group 2 (n = 50), which received no antibiotics. Patients were followed up weekly for 30 days, regarding to SSI, by a blinded surgeon. The Centers for Disease Control and Prevention definitions and classification of SSI were adopted. There was no statistical difference between the groups in regard to age, body mass index, duration of operation, and total resection weight. SSI rates were 2% and 14% in groups 1 and 2, respectively (P = 0.03). In group 2, older patients and those with higher resection weight had significant higher SSI rates (P = 0.02 and P = 0.04, respectively). We observed that antibiotics use decreased SSI rates after reduction mammaplasty.
