Treatments studied
Part of Women’s health & pregnancy clinical trials.

This trial tests two medicines given during a planned C-section to see which is better at preventing heavy bleeding. It may help make delivery safer for healthy women having a scheduled cesarean.
This study compares two ways of giving the medicine oxytocin (which helps the womb tighten to reduce bleeding) after a C-section in women at high risk for heavy bleeding. It will see if giving it as a single injection or as a slow drip works better at preventing excessive blood loss.
This study tests whether giving calcium through an IV during a C-section can reduce blood loss during the procedure. It is for women who are having a C-section after labor has started and who have already received oxytocin to help with contractions.
This study tests whether giving calcium gluconate during a planned cesarean can reduce blood loss. It may be an option for women who are at least 35 weeks pregnant and have no conditions that affect calcium or heart rhythm.
This study tests if giving calcium gluconate during childbirth can reduce blood loss. It might help women having a vaginal delivery after 37 weeks of pregnancy.
This trial studies whether tranexamic acid can prevent heavy bleeding after a planned or urgent cesarean delivery in people with placenta previa. If you qualify, you may receive the study drug to help your body keep blood loss lower during and after surgery.
