Monitoring of Neuromuscular Blockade in the Intensive Care Unit: a Reliability Study

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)
