Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

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.
