Feasibility of Measurement of a Neuromuscular Block at the m. Trapezius
Conditions
Keywords
accelerometry, neuromuscular block, m. trapezius
Brief summary
Accelerometric Assessment of neuromuscular block during anaesthesia is routinely performed at the M. adductor pollicis. However, many operations require positioning of the patients with arms attached to the body. In these situations, the anaesthesiologist has no access to the m.adductor pollicis. In this study, a new position of accelerometry at the neck is evaluated: Stimulation of the n. accessorius with accelerometry of the m. trapezius.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recovery to a train of four ratio of 0.9 | 60 minutes | Comparison between time to recovery \[s\] to a train of four ratio of 0.9 between both groups |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| onset of neuromuscular block | 10 min | Comparison of onset time \[s\] between both groups. Onset time is defined as decrease of T1 to \< 5% of initial twitch height. |
