Comparing neuromuscular monitoring methods during anesthesia reversal

Comparison of the Performances of the Train-of-Four Ratio and the Modified Train-of-Four Ratio During Reversal of Deep Neuromuscular Blockade With Sugammadex

Observational Ankara University · NCT06220136

This study is testing two different ways to monitor muscle recovery during anesthesia to see which one helps prevent complications after surgery for adults aged 18 to 65.

What this trial studies

This observational study evaluates the performance of two neuromuscular monitoring techniques, the classical train-of-four ratio (cTOFR) and the modified train-of-four ratio (mTOFR), during the reversal of deep neuromuscular blockade using Sugammadex. The study aims to address the high incidence of postoperative residual neuromuscular block, which can lead to serious complications. By utilizing TOFscan, a 3-dimensional acceleromyograph, the researchers will assess the effectiveness of these monitoring methods in ensuring patient safety and improving outcomes. The study includes patients aged 18 to 65 with a normal BMI and excludes those with certain medical conditions or complications.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 65 with a BMI between 18.5 and 24.9 undergoing elective surgeries requiring neuromuscular blockade.

Not a fit: Patients with liver or kidney disease, muscle disorders, or those undergoing emergency surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance patient safety by reducing the incidence of postoperative residual neuromuscular block.

How similar studies have performed: Previous studies have shown promising results with similar neuromuscular monitoring approaches, indicating potential for success in this study.
