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.
Tranexamic Acid is a medication used to treat or prevent excessive blood loss from major trauma, post partum, surgery, tooth removal, nose bleeds, and heavy menstruation.
Other Names:
  • Cyklokapron
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame

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.
Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

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) compared with intravenous tranexamic acid administration is associated with a non-inferior risk of in-hospital red blood cell transfusion.
Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Blood product transfusions
Time Frame: Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)
Analyzed using an ANCOVA model. In such a model, bags of blood product will be included as a dependent variable, whereas dose of tranexamic acid and treatment will be included as covariates.
Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)
Re-operation for bleeding or tamponade
Time Frame: Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)
Analyzed with a binomial regression
Start of surgery to hospital discharge or 10 days maximum (whichever occurs first)
Duration of ICU stay
Time Frame: Number of hours in ICU are being collected at the Post-Operative Visit. Hour collection will start upon arrival at ICU post surgery and stop at ICU exit, up to 10 days maximum.
Analyzed using an ANCOVA model.
Number of hours in ICU are being collected at the Post-Operative Visit. Hour collection will start upon arrival at ICU post surgery and stop at ICU exit, up to 10 days maximum.
MACE (Death, non-fatal Myocardial Infarction (MI), or non-fatal stroke)
