The Precision and Arm-to-Arm Variation of Mechanomyography and Acceleromyography for Monitoring of Neuromuscular Block

DenmarkStarted 2007-05

Plain-language summary

The purpose of the study is the examine the precision of acceleromyography and mechanomyography during recovery from a neuromuscular blocking agent and to examine whether there is any difference in monitoring block at the dominant or non-dominant arm. Our hypothesis is that there is no significant difference in neither the precision nor the level of block in the contralateral arms.

Inclusion Criteria: * ASA I-III * General anesthesia \>1 hour * Surgery in supine position w. possibility of monitoring the neuromuscular block at both arms (n. ulnaris stimulation/thumb response) * Written informed content Exclusion Criteria: * Neuromuscular disorders, hepatic and renal dysfunction * Medication expected to interfere with the neuromuscular blocking agent * Allergy to any medication used during anaesthesia * Body weight less or exceeding 20% of ideal body weight * Pregnancy or breastfeeding

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
