Comparing two neuromuscular monitoring devices during surgery

Comparison of an Acceleromyography- and Electromyography-based Neuromuscular Monitor With TOF-Watch ® Monitor:a Pilot Study

Observational Huazhong University of Science and Technology · NCT05632107

This study is testing a new device that combines two methods for checking muscle function during surgery to see if it works better than a common monitor used today.

What this trial studies

This study evaluates a new device that combines acceleromyography (AMG) and electromyography (EMG) for monitoring neuromuscular blockade during elective surgeries. The goal is to determine the validity of this device in accurately assessing neuromuscular function and preventing residual effects after surgery. By comparing it to the widely used TOF-Watch® monitor, the study aims to improve the reliability and ease of neuromuscular monitoring in clinical practice. Participants will include patients undergoing elective surgery requiring muscle relaxation.

Who should consider this trial

Good fit: Ideal candidates are patients under 18 years old, classified as ASA Physical Status I to III, and scheduled for elective surgery that requires muscle relaxation.

Not a fit: Patients with known neuromuscular disorders, a history of allergic reactions to neuromuscular blocking agents, or those on medications affecting neuromuscular transmission may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety and effectiveness of neuromuscular monitoring, reducing the risk of complications from residual neuromuscular blockade.

How similar studies have performed: While the use of EMG in neuromuscular monitoring is gaining attention, this specific combination of AMG and EMG has not been previously reported, making this approach novel.
