Neuromuscular Blockade Monitoring

The goal of this clinical trial is to learn if using a monitor that measures muscle response can lower the amount of muscle relaxant medicine needed in adults who are treated in an intensive care unit (ICU) and need a continuous drip of a muscle relaxant called atracurium for more than 48 hours. The main questions it aims to answer are: Does using the monitor lower the infusion rate and total amount of atracurium given over 72 hours? Does using the monitor lower the complications related to atracurium use? Researchers will compare a group whose dose is guided by a muscle response monitor, aiming for a moderate level of muscle relaxation, to a group whose dose is guided by the usual bedside checks, to see if the monitor lowers the amount of medicine needed while keeping the same quality of care. Participants will: Receive atracurium as a continuous drip as part of their usual ICU treatment Have a small sensor placed on the wrist and hand to measure muscle response, if they are in the monitor group Be checked regularly by a nurse and a respiratory therapist, who will adjust the dose following a written plan Be observed closely for 72 hours, then followed until they leave the hospital .

The objective of this clinical trial is to evaluate the reliability of neuromuscular blockade monitoring in adult intensive care patients depending on the clinical context. The main questions it aims to answer are as follows: * Detection of an anomaly at ulnar "TOF" stimulation in patients without neuromuscular blockade * Absence of adverse events during clinical monitoring of neuromuscular blockade (every 24 hours): absence of respiratory effort movements or patient-ventilator asynchrony (safety)

The purpose of this clinical study is to collect and assess feedback from clinical users regarding the functionality and device use and collection of raw parameter date from the NMT Sensor and NMT Cable.

This randomized controlled study aims to evaluate the effects of deep versus moderate neuromuscular blockade on intraoperative driving pressure and the development of postoperative critical respiratory events in patients undergoing abdominal surgery under general anesthesia.

In clinical anesthesiologic practice, most institutions use acceleromyography in order to assess the degree of a neuromuscular block. The aim of the present study is to assess a new device using mechanomyography. Until recently, this method was reserved for experimental settings. It seems to be able to work more precisely, and additionally, it offers the opportunity to use other stimulation patterns than acceleromyographic measurements. The investigation is divided into two parts: Part 1 compares the mechanomyograph directly with an acceleromyograph. In part 2, two mechanomyographs using different stimulation patterns are compared with each other.
