Who could benefit from this research

Could help

Pregnant people undergoing delivery (vaginal or cesarean) who are at risk for postpartum hemorrhage and are eligible for TXA use.

Less likely to help

People delivering under conditions where TXA is not indicated or contraindicated, or who choose not to participate.

What this research studies

This project tests different ways of giving tranexamic acid to pregnant people just before the baby is born, comparing timing (when it’s given), route (intravenous or intramuscular), and dose across vaginal births, cesarean deliveries, and in people with morbid obesity. It will measure how much TXA reaches the newborn through cord blood and breast milk, and track safety and outcomes during delivery and up to 6 weeks postpartum. The research integrates maternal-fetal medicine expertise with coagulation science to identify the best approach that maximizes maternal protection while minimizing fetal and maternal risks. If successful, the study could change standard practice to prevent postpartum hemorrhage more effectively in diverse birth scenarios.

Why it matters

Potential benefit: Could significantly reduce postpartum hemorrhage risk for mothers and provide safer, clearer guidance on TXA use around delivery.

How similar studies have gone: Prior data suggest TXA can help reduce bleeding, but this exact timing, dose, and route combination around cord clamping is under investigation and may yield new insights.
