Can a slower oxytocin infusion prevent dangerous blood pressure drops in C-Sections?
NCT ID NCT07784478
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This trial tests two standard methods of giving oxytocin, a drug that helps the uterus contract after childbirth, during planned C-sections under spinal anesthesia. One group receives a quick injection, while the other gets a slow infusion over 15 minutes. The goal is to see which method causes less of a drop in blood pressure and other heart-related changes, while still effectively preventing heavy bleeding. The study involves 60 healthy pregnant women aged 18-40 with a single baby at full term.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Oxytocin (Syntocinon) given as a rapid intravenous bolus or slow intravenous infusion
- What this could lead to
- If successful, this could identify a safer way to give oxytocin during C-sections, reducing blood pressure drops and improving maternal safety.
- What could go wrong
- This is a small, early-stage trial, so results may not apply to all patients. Both methods carry risks like blood pressure changes, and the optimal approach may vary by individual.
