Using a device to check labor epidural catheters before tubal ligation
Official title: Assessing Labor Epidural Catheter Dysfunction for Tubal Ligation in Parturients Using CompuFlo® CathCheck™ System: A Pilot Study
Run by Ohio State University · NCT07720908 · Data updated 2026-11-12
This pilot study tests whether the CompuFlo CathCheck system can reliably tell if a labor epidural catheter is functioning before a postpartum tubal ligation.

Is this trial a fit for you?
✓Likely a good fit
Postpartum women (≥18 years) who delivered vaginally, elected for tubal ligation, and have an indwelling labor epidural catheter.
✕Probably not a fit
Patients not using a labor epidural catheter or not undergoing postpartum tubal ligation may not benefit from this assessment tool.

What this trial studies
This prospective pilot study evaluates an objective tool, the CompuFlo CathCheck System, to assess the function and placement of a labor epidural catheter before reactivation for postpartum tubal ligation. Researchers compare the device’s pressure measurements and waveform signals with standard clinical checks to identify functional versus dysfunctional catheters. The goal is to see if this approach reduces failed reactivations and the need for alternative anesthesia while improving patient safety. Eligible participants are postpartum women who delivered vaginally and are planning an elective tubal ligation with an existing epidural, and who can consent in English.
Why it matters
Potential benefit: If successful, the device could improve catheter assessment and reduce failures, potentially lowering the need for additional anesthesia and enhancing safety for postpartum tubal ligation.
How similar studies have gone: Prior clinical methods have limitations; this is a pilot to determine whether a standardized, objective catheter assessment approach can add value.
