Dural Puncture Epidural (DPE) Technique in Labor Analgesia

Official title: Dural Puncture Epidural (DPE) Technique: Efficacy and Safety Overview.

Run by Ohio State University · NCT07704554 · Data updated 2026-11-12

Is this trial a fit for you?

Likely a good fit

Women with a term singleton pregnancy (37–42 weeks) requesting epidural analgesia and able to consent.

Probably not a fit

Results may show no improvement with DPE or identify subgroups where benefits are limited.

What this trial studies

This is a single-center, prospective observational study at The Ohio State University Wexner Medical Center. It investigates the DPE technique, where the dura is punctured with a spinal needle to confirm correct epidural placement by CSF visualization, before any intrathecal medication is given. Primary outcome is the rate of successful CSF visualization after dural puncture; secondary outcomes include overall epidural success, provider confidence, analgesia effectiveness, maternal satisfaction, need for rescue analgesia, and delivery and neonatal outcomes. The study describes patient selection among term singleton pregnancies requesting epidural analgesia and excludes those with chronic pain, spine issues, infections, or language barriers. It contributes to understanding whether DPE can improve accuracy and safety of labor neuraxial analgesia.

Why it matters

Potential benefit: If successful, DPE could improve epidural placement accuracy and analgesia during labor, potentially reducing failure and need for rescue analgesia.

How similar studies have gone: Prior evidence on DPE is limited and mixed, making this characterization relatively novel.
