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.

|---|---|---|
| Surgical intervention | Experimental | Patients undergoing a surgical intervention within the CHU Brugmann with utilisation of rocuronium. Receives: Device: Monitoring of neuromuscular transmission |
What is being measured
The primary outcome is the main question the study is designed to answer.
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

Clinical summary

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.
