Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Tranexamic Acid

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.


Treatment: Drugs: Tranexamic Acid
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.
