Electromyography and Acceleromyography in Ventilated ICU Patients

Neuromuscular Monitoring Clinical Trial

Official title: The Effectiveness of Electromyographic- and Acceleromyographic-based Monitors in Diagnosing Pre-existing Train-of-four Fade in Ventilated ICU Patients

Status Terminated

Clinical Trial Summary

In intensive care unit (ICU) patients who are mechanically ventilated for a longer period of time, there might be a difference in accuracy and performance of neuromuscular transmission monitoring [as measured by the train-of-four (TOF)%] due to a pre-existing TOF fade, correlated to some form of acquired muscle weakness. The investigators therefore propose to search for and compare the optimal monitoring techniques (acceleromyography vs. electromyography) and the optimal muscle monitoring site (peripheral-adductor pollicis vs. central-corrugator supercilii) in ICU patients who require prolonged mechanical ventilation.

Clinical Trial Description

The following neuromuscular transmission monitors will be used in the study: an electromyography-based monitor (TetraGraph, Senzime AB, Uppsala, Sweden) and two devices that are the newer generation of quantitative monitoring using three-dimensional acceleromyographic technology: Stimpod (Xavant Technology, Pretoria, South Africa) and TofScan (IDmed, Marseilles, France), both of which require minimal setup for use.

The stimulation pattern of both ulnar and facial nerves will be train-of-four (TOF) delivered every 1 minute, and the mean of three consecutive measurements will be calculated as the TOF% for that patient. Patients will be tested every 24 hrs, once a day, at the same time, over the 72 hrs the study will take place in the ICU. ;
