Prediction of the Recovery of Neuromuscular Transmission After Curarization

Not Applicable

Completed

• Conditions: Neuromuscular Blockade
• Interventions: Device: Monitoring of neuromuscular transmission

• Registration Number: NCT03550664
• Lead Sponsor: Brugmann University Hospital

Brief Summary

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.

Group	Intervention	Description
Surgical intervention	Monitoring of neuromuscular transmission	Patients undergoing a surgical intervention within the CHU Brugmann with utilisation of rocuronium.

Primary Outcome Measures

Name	Time	Method
TOFScan recording	1 day	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.
