TOF3D mechanomyograph for monitoring neuromuscular block during anesthesia.

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

Not applicable Interventional Klinikum Hersfeld-Rotenburg · NCT07371377

This project will test whether the TOF3D mechanomyograph measures muscle relaxation more precisely than standard acceleromyography in people having surgery under general anesthesia.

What this trial studies

The trial compares a new mechanomyography device (TOF3D) with standard acceleromyography in patients receiving neuromuscular blocking drugs during general anesthesia. Part 1 directly compares mechanomyograph readings to acceleromyograph readings, while Part 2 compares two mechanomyography modes that use different stimulation patterns. Investigators will record the time course of the neuromuscular block intraoperatively. Patients with anticipated difficult airway, increased aspiration risk, pregnancy, or neuromuscular disorders are excluded.

Who should consider this trial

Good fit: Adults scheduled for surgery under general anesthesia who will receive neuromuscular blocking agents and who do not have pregnancy, known neuromuscular disorders, a difficult airway, or elevated aspiration risk.

Not a fit: People who are pregnant, have neuromuscular disorders, have a known or anticipated difficult airway, or are not receiving neuromuscular blockers would not be eligible and would not benefit directly from this device.

Why it matters

Potential benefit: If successful, the device could provide more precise monitoring of muscle relaxation and help reduce the risk of residual paralysis after anesthesia.

How similar studies have performed: Mechanomyography has primarily been used in experimental settings and some reports suggest greater precision than acceleromyography, but direct clinical comparisons remain limited.
