Can a higher dose of labor drug shorten delivery time?
NCT ID NCT05782816
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a higher starting dose of oxytocin (a drug used to start or speed up labor) could shorten the time from induction to delivery in first-time mothers. 170 women were randomly assigned to receive either a low or high dose. Researchers also looked at whether the dose affected the type of delivery (vaginal or C-section) and the health of both mother and baby.
