Clinical Trial Summary

This study aims to compare two monitoring methods of neuromuscular blockade - Kine-myography and Electromyography. The main questions to answer are: - are electromyography and kine-myography interchangeable - is electromyography linked to fewer fault results - is electromyography using lower energy to stimulate nerves The type of study is a multicentric observational clinical trial. Subjects are patients undergoing general anaesthesia with the use of rocuronium or cis-atracurium. In each patient, the neuromuscular blockade will be monitored using kine-myograph and electromyography simultaneously.

Description:

Informed consent will first be obtained from the patient for inclusion in the study. Consent will be obtained during an examination by the anaesthesiologist providing anaesthetic care during surgery in the anteroom of the operating theatre. Once informed consent has been obtained, a routine orientation examination will be performed by the anaesthetist and routine pre-operative preparation (provision of peripheral venous access, risk assessment for airway obstruction, etc.) will be performed. The patient will then be transported to the operating theatre. In the operating room, patient monitoring will be initiated, including the deployment of sensors to monitor the depth of neuromuscular blockade. The KMG sensor will be placed on the right arm and the EMG sensor on the left arm. After deployment of the sensors, upper limb fixation will be performed by the anaesthetic nurse. The fixation will be performed with splints compatible with the operating table. Fixation of the limbs and sensor with adhesive tape will not be used. The anaesthesia will then be induced. Propofol and sufentanil will be administered at the discretion of the anaesthetist providing anaesthetic care. Once sufficient depth of sedation has been induced, calibration of the sensors monitoring the depth of neuromuscular blockade will be performed. After calibration of the sensors, the supramaximal current to the CRF will be recorded. The measurement interval will be set to 20 s. After securing the airway, the interval will be extended to 5 - 15 min according to the nature of the surgery and the discretion of the anaesthesiologist providing anaesthetic care. The number of twitches (PCT) and the Train Of Four (TOF) value will be recorded throughout the procedure. On emergence from anaesthesia, the measurement interval will be set to 1 minute. Once sufficient depth of neuromuscular blockade has been reached to allow extubation, monitoring of the depth of neuromuscular blockade will be discontinued. If during the measurement of the depth of neuromuscular blockade a value is measured that is highly suspected to be in error, this suspicion will be recorded in the CRF with a justification.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Measurement variability	A primary aim is to demonstrate that measurement of the depth of neuromuscular blockade using kinemyography is associated with a higher measurement variability than measurement of the depth of neuromuscular blockade using electromyography.	From sensor calibration til extubation at TOF higher than 90%.Maximum length of measurement is 6 hours.
Secondary	supramaximal electric stimulus	A secondary aim is to demonstrate that measuring the depth of neuromuscular blockade using kinemyography is associated with a higher supramaximal electric stimulus than measuring the depth of neuromuscular blockade using electromyography.	From sensor calibration til extubation at TOF higher than 90%.Maximum length of measurement is 6 hours.
Secondary	TOF overestimation	The primary objective of the study is to demonstrate that there is measured higher TOF when using KMG to monitor the depth of neuromuscular blockade compared to using EMG sensor to monitor the depth of neuromuscular blockade.	From sensor calibration til extubation at TOF higher than 90%.Maximum length of measurement is 6 hours.
