Does a multiport catheter beat a Single-Port for labor pain?
NCT ID NCT01861821
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study tested whether a flexible catheter with three openings (multiport) provides better pain relief during labor than a standard single-opening catheter. 650 women in labor received one of the two catheters for epidural medication. The goal was to see if the multiport design improves the chance of complete pain relief without needing extra doses.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- flexible epidural catheter (multiport or uniport)
- What this could lead to
- If the multiport catheter works better, it could provide more reliable pain relief during labor and reduce the need for extra interventions.
- What could go wrong
- This is a completed study comparing two devices, so results are already known. The difference between catheters may be small, and individual responses vary.
