Finding the best way to use tranexamic acid to prevent postpartum bleeding

OPTIMUM OB-TXA: Optimal TIMing, route and dose of tranexamic acid prior to UMbilical cord clamp for postpartum hemorrhage prevention

NIH-funded research Inova Health Care Services · NIH-10903995

This study is looking at the best ways to use a medication called tranexamic acid to help prevent heavy bleeding after childbirth, and it's for women who are having a baby vaginally, through a cesarean section, or who have obesity, so we can find the safest and most effective options for both moms and their babies.

What this research studies

This research investigates how to effectively use tranexamic acid (TXA) to prevent postpartum hemorrhage (PPH) by examining different timing, routes, and doses of administration before umbilical cord clamping during childbirth. The study will focus on three specific groups: women delivering vaginally, those undergoing cesarean sections, and those with morbid obesity. Researchers will measure TXA levels in umbilical cord blood and breast milk, as well as monitor clinical outcomes for mothers and newborns at delivery and two to six weeks postpartum. The goal is to maximize benefits for mothers while minimizing risks for both mothers and their babies.

Who could benefit from this research

Good fit: Ideal candidates for this research include pregnant women who are planning to deliver vaginally or via cesarean section, particularly those with morbid obesity.

Not a fit: Patients who are not pregnant or those who do not plan to deliver in the study's timeframe may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could significantly reduce the incidence of postpartum hemorrhage, improving maternal health outcomes.

How similar studies have performed: Previous research has shown that tranexamic acid can be effective in reducing bleeding in various surgical settings, suggesting potential success in this novel application for postpartum hemorrhage.
