Optimal TIMing, route and dose of tranexamic acid prior to UMbilical cord clamp for postpartum hemorrhage prevention (OPTIMUM OB-TXA)
The study is designed to test the hypothesis that the same dose of TXA prior to delivery or pre-cord clamp will be sufficient to achieve hemorrhage prevention targets and define dosing schema for intravenous (IV) and intramuscular (IM).
