Post-Mastectomy Surgical Pocket Irrigation With Triple Antibiotic Solution vs Chlorhexidine Gluconate: A Randomized Controlled Trial Assessing Surgical Site Infections in Immediate Tissue Expander Breast Reconstruction

Breast reconstruction with tissue expander (TE) remains the gold standard of breast restoration after mastectomy. During the first stage of reconstruction, a TE is placed under chest muscles and slowly inflated postoperatively over the period of several weeks. After desired volume of TE is achieved it is exchanged for permanent breast prosthesis during another surgery (second stage of reconstruction). Postoperative wound infection after placement of TE can lead to devastating consequences both for patients and a surgeon. Frequently, surgical site infection requires additional surgeries and resulting in the removal of TE and long term IV antibiotic therapy. Therefore, during breast reconstruction procedures all possible measures are implemented to reduce postoperative infection rate. Several studies demonstrated that intra-operative irrigation of surgical wounds with antibiotic containing solution before insertion of breast TE decreases postoperative infection rate. This approach is currently adopted as a standard of care within plastic surgery clinical community.

The investigators intend to perform a prospective randomized study and compare the incidence of surgical wound infection between mastectomy wounds irrigated with triple antibiotic solution (one side) and 0.05% CHG (opposite side) in patients undergoing bilateral breast reconstruction.
