The effect of tranexamic acid on blood loss in liposuction: a randomized controlled study.

[BACKGROUND] Liposuction is one of the most common procedures in the practice of plastic surgery. Since it evolved, continuous modifications have been to decrease blood loss so that patients are hemodynamically stable intra- and postoperatively. Tranexamic acid (TXA) has long been used for its antifibrinolytic properties that were beneficial in reducing blood loss, rate of transfusion, and hemoglobin drop in major trauma and surgeries. Its use in plastic surgery, however, is still limited. In this study, we aim to illustrate the effect of intravenous (IV) and local infiltration of TXA on blood loss in liposuction surgery.

[METHODS] Between April 2019 and April 2021, 90 patients who requested liposuction for various body parts were randomly allocated into 3 equal groups: control group, IV TXA, and local infiltration of TXA. A sample was taken from infranatant and sent for hematocrit calculation. Volume of blood in lipoaspirate was then calculated. Patients were assessed for blood loss and postoperative bruising.

[RESULTS] Volume of blood loss in lipoaspirate was considerably lower in the TXA groups, with 60% decrease in blood loss for the local TXA group in comparison with the control group. TXA has also been shown to markedly decrease bruising tendency in postoperative liposuction patients.

[CONCLUSIONS] TXA can be used to decrease blood loss in large-volume liposuction, modify the need for blood transfusion intra- and postoperative, and improve the results of liposuction procedure without the need for multiple sessions.
