DEPOSITION - Decreasing Postoperative Blood Loss by Topical vs. Intravenous Tranexamic Acid in Open Cardiac Surgery (DEPOSITION)
December 1, 2023 updated by: Population Health Research Institute
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.

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 (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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Topical Tranexamic Acid/Placebo
Topical Tranexamic Acid 5g to 10g (50 to 100mL) or placebo.
The topical will be poured into the pericardial and mediastinal cavities after protamine administration.

Active Comparator: Intravenous Tranexamic Acid/Placebo
Intravenous Tranexamic Acid 1 to 10g (10 to 100mL) or placebo administered intravenously at the induction of anesthesia as a bolus-infusion.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The proportion of patients experiencing an in-hospital seizure
Time Frame: Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)
|
To determine in patients undergoing on-pump cardiac surgery, if topical tranexamic acid (intra-pericardial) is superior to the usual intravenous tranexamic acid administration for reducing the risk of in-hospital seizure.

To determine in patients undergoing on-pump cardiac surgery, if topical tranexamic acid (intra-pericardial) compared with intravenous tranexamic acid administration is associated with a non-inferior risk of in-hospital red blood cell transfusion.
