Endobronchial administration of tranexamic Acid for controlling pulmonary bleeding: a pilot study.

Background: Tranexamic acid (TA) is a synthetic antifibrinolytic substance used for short-term control of bleeding. However, control of pulmonary bleeding with endobronchial administration of TA in more than 2 cases has not been attempted earlier.

Objective: We tested the feasibility of endobronchial administration of TA for controlling pulmonary bleeding.
