Effect of Intravenous and Topical Tranexamic Acid on Drain Output in Breast Reduction Surgery

This single-center, prospective, randomized controlled trial investigates the effect of tranexamic acid (TXA) on postoperative drain output and recovery following bilateral reduction mammaplasty. While TXA is widely utilized to minimize intraoperative blood loss, its role in optimizing postoperative wound healing and fluid management in plastic surgery remains underexplored. Participants undergoing bilateral breast reduction will be randomized to receive either intravenous TXA or no TXA at the time of surgery. In addition, each breast will be independently randomized to receive TXA or saline via the closed-suction drain after skin closure. This split-body design enables a controlled intra-individual comparison of local TXA effects, while concurrently assessing systemic administration in a parallel fashion. Primary outcomes include total drain output per breast and time to drain removal. Secondary endpoints include the incidence of postoperative hematoma and patient reported outcomes. All outcome measures will be recorded using standardized protocols and assessed by blinded evaluators where applicable. Participants will be followed until 30 days postoperatively. Given the established safety profile of TXA and the relatively low-risk nature of the intervention, no independent data monitoring committee has been appointed. The study has been approved by the local IRB and will adhere to institutional standards for adverse event monitoring and reporting.
