Tranexamic Acid Irrigation in Liposuction: A Double-Blind, Half-Body, Randomized, Placebo-Controlled Trial.

[BACKGROUND] Hematomas are common complications following plastic and esthetic surgeries. Large and complex hematomas might result in prolonged hospitalization, further interventions, additional expenses, and poor esthetic outcome. Tranexamic acid (TXA), an antifibrinolytic agent, has long been used to reduce blood loss. Its use in the field of plastic surgery has gained popularity recently. Several studies have presented the ability of TXA to reduce blood loss, hematomas, and ecchymoses after liposuctions. However, the proper dose and the route of administration remained controversial.

[OBJECTIVE] The objective of the study was to quantify the effect of a low dose of TXA in an irrigation method in reducing hematomas and ecchymoses following liposuction.

[METHODS] A prospective randomized controlled trial was conducted. Following liposuction, 400 mg of TXA were administered in an irrigation protocol to one side of the body in each patient, while the other side was administered with saline. The patients were photographed on 1, 2, 4, and 11 post-operative days. Ecchymosis and hematoma were measured and rated.

[RESULTS] No statistical difference was observed between the intervention and control groups in terms of RBC in liposuction area (p = 0.11), RBC in lipoaspirate (p = 0.79), bruising size on days 1, 2, 4, and 11 (p = 0.68, 0.21, 0.42, and 0.75), and average ecchymosis score on the same days (p = 0.34, 0.72, 0.09, and 1) CONCLUSIONS: The use of a low-dose TXA irrigation solution did not demonstrate a statistically significant difference in post-operative hematoma formations rates and subsequent ecchymosis size and scale.
