[Role of Tranexamic Acid in Plastic Surgery: a Systematic Review]

Background: Bleeding events in surgery are a problem and can lead to revision surgery and bleeding anaemia, which sometimes must be treated by blood transfusion. Tranexamic acid is an antifibrinolytic agent and is already known for its role in the prevention and treatment of perioperative bleeding in the fields of orthopaedics, cardiovascular surgery and gynaecology. In plastic surgery, the use of tranexamic acid is increasing in popularity and has already been described in individual studies.

Methods: A literature search was performed using the database MEDLINE from the United States National Library of Medicine (NLM). The keywords "tranexamic acid in plastic surgery", "intravenous tranexamic acid in plastic surgery", "topical tranexamic acid in plastic surgery" and "subcutaneous tranexamic acid in plastic surgery" were used. The search was limited to the period from 2010 to 2023. The studies were analysed according to the level of evidence, validity and availability and divided into three groups for the topical, intravenous or subcutaneous application of tranexamic acid. Randomised controlled trials and non-randomised prospective and retrospective cohort studies were included in the systematic review. Studies from other disciplines, review articles, technical notes, experimental studies, letters to the editor, comments and case reports were excluded.

Results: The literature search resulted in a total of 135 papers. Of these, 56 papers were assessed as relevant to plastic surgery. After further analysis, 41 papers were excluded using the exclusion criteria described above. Fifteen studies were finally included in the present work and recommendations for possible applications such as intravenous, topical and subcutaneous application of tranexamic acid, including the indications, contraindications and dosage formulas were developed.

Discussion: Although the current study situation on the use of tranexamic acid is limited, the results show more advantages than disadvantages for perioperative use. Establishing the use of tranexamic acid in plastic surgery could facilitate the reduction of perioperative bleeding and lead to more precision in surgery, and it could enable a rapid removal of drains. However, following the analysis of benefit and risk factors, further randomised controlled trials are required for use in plastic surgery.
