Decreasing Postoperative Blood Loss by Topical vs. Intravenous Tranexamic Acid in Open Cardiac Surgery

DEPOSITION: Pilot Study Decreasing Postoperative Blood Loss by Topical vs. Intravenous Tranexamic Acid in Open Cardiac Surgery

Summary

The aim is to conduct a double-blinded single-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TA) versus the usual intravenous TA in patients undergoing cardiac surgery at the Hamilton General Hospital. This pilot study will assess the feasibility to perform a large randomized international trial exploring this objective.

Detailed description

Postoperative bleeding related to open cardiac surgery increases the rates of complications and mortality. It results from the blood thinners that are needed for use. Intravenous tranexamic acid (TA) has become a mainstay in cardiac surgical procedures for decreasing bleeding and minimizing transfusion requirements. Although intravenous TA is usually well tolerated, there is a well-known risk (1 to 4%) of postoperative seizures. This is due to the similarity between TA and the brain tissues. The aim is to eliminate the risk of seizures but to maintain the protection against bleeding. When TA is used directly on the tissues (topically) for other type of surgeries (joints), TA is effective to reduce blood loss and transfusions. The aim is to prove that direct application of TA on the heart can eliminate postoperative seizures and reduce the amount of blood transfusions in patients who have cardiac surgery.
