The TOF3D Mechanomyograph. Evaluation of a New Device for Assessment of the Neuromuscular Block.

Klinikum Hersfeld-Rotenburg50 enrolled

Overview

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.
