Comparing sugammadex and neostigmine for reversing muscle relaxation during outpatient ERCP

Comparison of Efficacy of Sugammadex Versus Neostigmine in Reversing Neuromuscular Blocks in Patients Having Outpatient Endoscopic Retrograde Cholangiopancreatography (ERCP). A Randomized, Double-Blinded Trial

Phase 3 Interventional The Cleveland Clinic · NCT06136585

This study is testing whether sugammadex or neostigmine works better to reverse muscle relaxation in adults undergoing a specific outpatient procedure called ERCP.

What this trial studies

This trial aims to compare the effectiveness of two medications, sugammadex and neostigmine, in reversing muscle relaxation caused by rocuronium in patients undergoing outpatient endoscopic retrograde cholangiopancreatography (ERCP) at the Cleveland Clinic. It is a single-center, assessor-blinded, parallel group randomized trial involving 80 adult patients classified as ASA physical status 3 and 4. Participants will be randomly assigned to receive either sugammadex or neostigmine, with randomization stratified by age and type of procedure. The anesthesiologists will know the group assignments, but patients and outcome assessors will remain blinded.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with ASA physical status 3 or 4 scheduled for elective outpatient ERCP.

Not a fit: Patients with difficult airways, neuromuscular disorders, end-stage renal disease requiring dialysis, or those who are pregnant or breastfeeding will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective and safer option for reversing neuromuscular blocks in patients undergoing outpatient procedures.

How similar studies have performed: Previous studies have shown varying success with similar approaches, but this specific comparison of sugammadex and neostigmine in the outpatient ERCP setting is novel.
