What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This pilot study tests a device called the CompuFlo® CathCheck™ System to see if it can accurately assess whether a labor epidural catheter is still functional before it is reactivated for postpartum tubal ligation. Researchers will compare the device's readings with standard clinical checks in 120 women who had a vaginal delivery and still have their epidural catheter in place. The goal is to reduce failed epidural reactivation and improve patient safety.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
CompuFlo® CathCheck™ System
What this could lead to
If successful, this device could help anesthesiologists quickly tell if a labor epidural catheter is still working, reducing failed blocks and the need for extra procedures.
What could go wrong
This is a small pilot study, so results may not apply broadly. The device might not be more accurate than standard checks, and technical issues could limit its use.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 120 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2024

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Female participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria * Age ≥ 18 years * Postpartum women electing to undergo tubal ligation with an indwelling labor epidural catheter * Ability to provide informed consent in English * Vaginal delivery Exclusion Criteria * Parturients not receiving labor epidural analgesia or receiving an alternative anesthetic technique during labor and delivery * Epidural catheter located \>2 cm from the documented insertion depth at initial placement * Planned elective cesarean delivery * Chronic pain conditions (e.g., chronic low back pain, sickle cell disease) * Chronic opioid use disorder * Chronic gabapentin use * Uncontrolled mood disorders that, in the investigator's judgment, may interfere with study participation or interpretation of study outcomes * Prisoners or incarcerated individuals
