C-Section drug showdown: which is safer for baby?
NCT ID NCT06921473
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two common drugs, ephedrine and norepinephrine, to treat low blood pressure during C-sections under spinal anesthesia. Low blood pressure can reduce blood flow to the baby, so doctors want the safest option. The trial included 102 pregnant women having planned C-sections. Researchers measured the baby's umbilical cord pH after birth to see which drug led to less acidosis (too much acid in the blood).
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ephedrine and norepinephrine
- What this could lead to
- If this trial shows one drug is safer for the baby, it could help doctors choose the best treatment for low blood pressure during C-sections.
- What could go wrong
- This is a small, completed Phase 4 trial with 102 participants. Results may not apply to all pregnancies, and both drugs have known side effects like rapid heart rate.
