Tranexamic Acid Usage in Bilateral Mastectomy to Reduce Post-surgical Drainage

Tranexamic acid (TxA) is a drug that was approved by the FDA in 1986. It is an antifibrinolytic drug - this means that it is used to promote blood clotting by preventing the breakdown of blood clots that the participant's body naturally forms. TxA is very commonly used to control bleeding in a variety of surgeries, such as orthopedic and gynecologic procedures, and is available in both the injectable (delivering the drug through the veins) and oral forms. However, its use is still not commonplace in the setting of elective breast surgery, because it hasn't been extensively studied in this field. Because it is not currently FDA-approved for use in elective breast surgery, this would make the drug "investigational" for this study. Because of its current use in other fields, TxA seems to have a great deal of potential in reducing the amount of post-operative time that breast drains need to be kept in place, the frequency of adverse events during wound healing such as bleeding and fluid accumulation, and overall fluid drainage amount. This would serve to improve the overall process of post-operative healing following a mastectomy procedure. Currently, the use of TxA is approved through the injectable route at Northwestern, but it is not approved for administration by the topical route. Previous studies have shown that TxA given through the topical route of administration in breast reduction surgery reduced post-surgical drainage and fluid accumulation. In this study, the use of 3% (3 grams of TxA in 100 ml of saline) TxA through the topical route by applying it to the breast wound of one breast as a direct fluid irrigation will be investigated. This will be done as a fluid wash, where the TxA will be in a syringe, and just before wound closure the TxA will be sprayed onto the wound site. The other breast will undergo the same procedure, but will receive normal saline solution instead of TxA. The procedure of interest here is a prophylactic bilateral mastectomy, which is
