Predicting neuromuscular block during anesthesia

Predictive Modelling of the Intraoperative Train-of-Four (TOF) Ratio

Observational Universitair Ziekenhuis Brussel · NCT04518761

This study is trying to see if a new way of measuring muscle response during anesthesia can help doctors better manage the use of a muscle relaxant in adults having non-heart surgery.

What this trial studies

This observational study aims to develop a predictive model for the Train-of-Four (TOF) ratio during anesthesia by analyzing neuromuscular monitoring data. It focuses on adult patients undergoing noncardiac surgery who receive general anesthesia with the neuromuscular blocking agent Rocuronium. The study utilizes electrical stimuli applied to the ulnar nerve to measure the motor response of the thumb, which is then analyzed to determine the effectiveness of neuromuscular blockade. The goal is to enhance the evidence-based use of neuromuscular blocking agents in clinical practice.

Who should consider this trial

Good fit: Ideal candidates are adult patients aged 18 and older undergoing noncardiac surgery with general anesthesia requiring Rocuronium.

Not a fit: Patients with known neuromuscular diseases or those receiving different neuromuscular blocking agents during the same procedure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the safety and effectiveness of neuromuscular blocking agents during surgery.

How similar studies have performed: While the approach of using TOF monitoring is established, the specific predictive modeling aspect of this study may offer novel insights.
