About this study

Official title: Prediction of the Recovery of Neuromuscular Transmission After Curarization, Pilot Study

The vast majority of patients receive neuromuscular blockers during surgical procedures, either as a single injection to facilitate intubation or as repeated injections to induce muscle relaxation necessary for surgery. The action of neuromuscular blockers is monitored by measuring the contraction force of the adductor of the thumb after stimulation of the ulnar nerve.Different types of stimulation, such as train-of-four (TOF), post- Tetanus count (PTC), double-burst stimulation (DBS) measure different degrees of curarization.The duration of action of neuromuscular blockers has significant interindividual variability. If the investigators know how to measure the degree of curarization of a patient at a given time, it is difficult to know how long it will take to recover neuromuscular function.

The purpose of this study is to determine if the individual recovery of a patient can be predicted form data obtained at the beginning of his/her recovery curve. The investigators propose to record all neuromuscular transmission monitoring data in 100 patients. From these data, the investigators will try to develop an algorithm that would extrapolate the recovery curve of an isolated patient from the fist neuromuscular monitoring data.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Monitoring of neuromuscular transmissionDevice

    Monitoring of neuromuscular transmission will be done by TOFScan (IdMed, Marseille, France). This device is CE marked, and is used routinely in daily clinical practice. Prior to induction of anesthesia, the TOFScan is placed on a patient's hand and the two stimulation electrodes (ECG electrodes) are placed at the level of the ulnar nerve at the wrist. After induction of anesthesia and before administration of a curare, the TOFScan is calibrated according to the manufacturer's instructions. The TOFScan is placed in automatic mode, it will then automatically adapt its mode of stimulation to the depth of the curarization. The TOFScan measurements will be recorded on a PC connected to the TOFScan.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. TOFScan recording

    Recordings of the TOFScan device (monitoring of the neuro-muscular transmission) during the entire length of the surgery are automatically stored on PC. This data will be used to conceive a mathematical algorithm predicting the decurarisation curve of an individual patient.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Monitoring of neuromuscular transmission in people with Neuromuscular Blockade, run by Brugmann University Hospital at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

TOFScan recording (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03550664, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2020.
