Using ultrasound to predict difficult epidural placement during labor

Official title: Prospective Observational Study: Ultrasound Predictors of Difficulty in Performing Epidural Anesthesia for Labor in Pregnant Patients.

Run by University of Padova · NCT07056166 · Data updated 2026-11-12

This tests whether a quick ultrasound of the lower back can help predict when placing an epidural will be difficult for women in labor.

Is this trial a fit for you?

Likely a good fit

Pregnant women aged 18 years or older who request an epidural for labor analgesia at the enrolling hospital and provide consent are ideal candidates.

Probably not a fit

People who are not planning an epidural, are under 18, or give birth at a different hospital would not benefit from participation in this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-center, prospective observational study at the University Hospital of Padua enrolls pregnant women who request epidural analgesia during labor. Participants receive a brief lumbar ultrasound before the epidural procedure, and clinicians record demographic, anatomical, ultrasound measurement, and procedural data. Investigators will compare ultrasound findings with how easy or difficult the epidural placement was. No experimental treatments are given and all care follows standard clinical practice.

Why it matters

Potential benefit: If successful, this could help clinicians anticipate difficult epidural placements so they can prepare appropriate equipment or expertise and reduce procedure time and complications.

How similar studies have gone: Prior studies have shown that lumbar ultrasound can improve landmark identification and reduce technical failures, so this work builds on encouraging existing evidence rather than being entirely novel.
