Prospective Study Assessing the Effect of Local Infiltration of Tranexamic Acid on Facelift Bleeding.

[BACKGROUND] Rebound bleeding during facelift surgery is a major cause of facelift hematomas. Subcutaneous infiltration of tranexamic acid (TXA) combined with lidocaine and epinephrine was recently retrospectively shown to decrease rebound bleeding. No study has prospectively examined the effect of subcutaneous TXA on intraoperative and postoperative bleeding during facelift surgery.

[OBJECTIVES] The aim of this study was to prospectively demonstrate that TXA combined with local anesthesia safely reduces the effects of rebound bleeding, reduces operative time, and decreases postoperative drainage.

[METHODS] This was a prospective, single-surgeon, case-control study performed between July 2019 and March 2020. Thirty-nine patients (35 female and 4 male; mean age, 64.9 years; age range, 49-80 years) underwent facelift surgery alone or in combination with facial rejuvenation procedures. All patients were injected subcutaneously with 1 or 2 mg/mL TXA + 0.5% lidocaine/1:200,000 epinephrine. Patient demographics, TXA dose, time to hemostasis, drain output, and minor and major complications were recorded.

[RESULTS] The mean time to hemostasis was 6.4 minutes for the left and right sides each. Average postoperative day (POD) 0 drain outputs were 13.9 mL (left) and 10.1 mL (right). Average POD 1 drain outputs were 15.1 mL (left) and 15.6 mL (right). Drains were removed from all patients on POD 1 or 2. There were 2 minor complications (flap necrosis plus infection, marginal mandibular neuropraxia) and no major complications.

[CONCLUSIONS] TXA safely and effectively decreased bleeding, operating room time, and drain output compared with traditional local anesthetic techniques. Our future goal is to determine if epinephrine can be completely removed from the local anesthetic and replaced with TXA for facelift surgery.
