Protest Trial: TXA vs Saline

Overview

To determine if endobronchial (topical) tranexamic acid used prophylactically prior to performing transbronchial biopsies in lung transplant recipients reduces bleeding risk.

Tranexamic acid (TXA) is an antifibrinolytic agent. It forms a reversible complex that displaces plasminogen from fibrin resulting in inhibition of fibrinolysis. It also inhibits proteolytic activity of plasmin. TXA is frequently used in clinical practice and can be administered via multiple delivery methods, including intravenous, nebulized, and topical. It has been shown to reduce blood loss in a variety of clinical settings without significant adverse effects. It has also been evaluated for prophylactic use with mixed results in reducing bleeding. In our current general pulmonary practice, topical TXA is used variably by pulmonologists during bronchoscopy for post-biopsy bleeding or pulmonary hemorrhage. The purpose of this research study is to determine if prophylactic topical TXA can reduce bleeding risk in lung transplant patients who undergo transbronchial biopsies. A finding of reduced bleeding would be significant as it could improve clinical outcomes, allow for improved diagnostic yield of biopsy samples, and improve patient experience. It therefore has the potential to change clinical practice and standardize bronchoscopy procedures.
