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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether monitoring the median nerve in the wrist works as well as the usual ulnar nerve for tracking muscle relaxant effects during surgery. Researchers will enroll 45 adults having elective surgery that requires muscle relaxants. The goal is to see if the median nerve provides reliable data, which could give anesthesiologists more options for ensuring patients recover safely from anesthesia.

What this could mean

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

What this could lead to
If successful, this could give anesthesiologists a better way to monitor muscle relaxant recovery, potentially improving patient safety during surgery.
What could go wrong
This is a small, early-stage study with only 45 participants, so results may not apply to all patients or surgeries. It focuses on monitoring, not treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * ASA I-III physical status * elective surgery requiring muscle relaxation * both arms are available during surgery in the same position for neuromuscular blockade monitoring * signed informed consent form Exclusion Criteria: * neruomuscular disorder in patient history (eg. stroke, myasthenia) * innervation problem in either arms (eg. carpal tunnel syndrome) * deformity to either arms (eg. Dupyurten contracture, severe arthritis) * Severe hepatic or renal insufficiency that affects muscle relaxant pharmacokinetics * skin lesions at the site of electrode placement * implanted pacemaker jelenléte * gravidity * muscle relaxant needs to be repeated during surgery
