Bleeding Clinical Trial
Official title:
Decreasing Postoperative Blood Loss by Topical vs. Intravenous Tranexamic Acid in Open Cardiac Surgery (DEPOSITION) Study
The aim is to conduct a double-dummy multi-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TxA) versus the usual intravenous TxA in patients undergoing on-pump cardiac surgery.
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 (TxA) has become a mainstay in cardiac surgical procedures for decreasing bleeding and minimizing transfusion requirements. Although intravenous TxA is usually well tolerated, there is a well-known risk (1 to 4%) of postoperative seizures. This is due to the similarity between TxA and the brain tissues. The aim is to eliminate the risk of seizures but to maintain the protection against bleeding. When TxA is used directly on the tissues (topically) for other type of surgeries (joints), TxA is effective to reduce blood loss and transfusions. The aim is to prove that direct application of TxA on the heart can eliminate postoperative seizures and reduce the amount of blood transfusions in patients who have cardiac surgery. ;
