Single Dose Versus 24 Hours Antibiotic Prophylaxis in Reduction Mammaplasty
Study Details
Study Description
Brief Summary
Setting: Translacional Surgery Graduation Program - Universidade Federal de São Paulo and Hospital das Clínicas Samuel Libânio - Universidade do Vale do Sapucaí. Background: Breast reduction is one of the most performed plastic surgery procedures. Antibiotics are widely prescribed, on an empirical basis, to prevent surgical site infections. However, there is a lack of evidence to support its use. Objective: To compare the influence of the use of prophylatic antibiotics as a single dose or for 24 hours on surgical site infection rates following reduction mammaplasty. Methods: Randomized trial of non-inferiority, with two parallel groups, double blinded. A total of 146 breast hypertrophy patients, with reduction mammaplasty already scheduled, will be enrolled. Patients will be randomly allocated to group A, that will receive antibiotics only at the anesthesia induction (n=73), or to group B, that will receive antibiotics at the anesthesia induction and for 24 hours (n=73). None of the patients will receive antibiotics after hospital discharge. Patients will be followed-up weekly, for 30 days, regarding surgical site infection. The Centers for Disease Control and Prevention criteria will be applied. A statistical analysis of the data will be performed.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Cephazolin Patients will receive antibiotics (1g cephazolin) intravenously at the anesthestic induction and every 6 hours for 24 hours |
Drug: Cephazolin
Patients undergoing reduction mammaplasty will receive 1g of cephazolin intravenously anesthetic induction and postoperatively every 6 hours, for 24 hours.
|
| Placebo Comparator: Sterile saline Patients will receive antibiotics (cephazolin) only at the anesthesia induction, and sterile saline intravenously every 6 hours for 24 hours |
Other: Sterile saline
Patients undergoing reduction mammaplasty will receive 1g of cephazolin intravenously anesthetic induction and intravenous sterile saline postoperatively, every 6 hours, for 24 hours.

Outcome Measures
Primary Outcome Measures
- Number of patients with surgical site infection (SSI) [30 days]
Patients will be monitored for the occurrence of SSI once weekly during the first 30 days following hospital discharge by a single surgeon who is blinded to their treatment group. SSI will be evaluated based on the definition adopted by the Centers for Disease Control and Prevention.
