Evaluating recovery from neuromuscular blocking agents

Estimation of Neuromuscular Transmission Recovery After Rocuronium Induced Block - Validation Study of a New Algorithm

Erasme University Hospital · NCT05716282

This study is testing a new way to estimate how long it takes for patients to recover from muscle relaxation after surgery using a specific medication called rocuronium.

What this trial studies

This observational study aims to validate a mathematical model that estimates the time required for patients to recover from neuromuscular blockade after receiving a single dose of rocuronium during surgery. By measuring neuromuscular transmission at the adductor pollicis using the TOFScan device, the study will assess the accuracy and precision of the recovery time estimation based on initial train-of-four measurements. The goal is to improve monitoring and management of neuromuscular recovery in surgical patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older scheduled for surgery requiring a single bolus of 0.6 mg/kg of rocuronium.

Not a fit: Patients with known allergies to rocuronium, significant renal or hepatic insufficiencies, or those with a BMI outside the range of 20-30 kg/m2 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate predictions of recovery times, enhancing patient safety and optimizing surgical outcomes.

How similar studies have performed: Previous studies have explored similar methodologies for neuromuscular monitoring, indicating potential for success in this approach.
