Continuous Remimazolam Administration by Gastroenterologists for Endoscopic Sedation.

Background and

Objectives

Gastrointestinal (GI) endoscopy requires safe and effective sedation. Remimazolam, an ultra-short-acting benzodiazepine, may offer advantages over traditional sedatives like midazolam and propofol, including rapid onset, short half-life, and a favorable safety profile. This study evaluates the feasibility, safety, and patient satisfaction of continuous remimazolam infusion administered by trained gastroenterologists for GI endoscopy. Materials and

Methods

This prospective registry included patients with ASA physical status I and II undergoing standard endoscopic procedures. Continuous remimazolam sedation was administered, with boluses given as needed. Vital signs were monitored, and patient satisfaction was assessed before and after the procedure using standardized questionnaires.

Results

A total of 159 procedures were performed in 141 patients. Sedation was successful in all patients, with a mean induction dose of 7.1 mg and total infusion of 15.1 mg. Recovery time averaged 3.3 min. Adverse events, including transient hypotension and hypoxia, occurred in 11.3% of patients but were easily managed. Most patients (97%) reported sufficient comfort, with an average satisfaction score of 8.1/10.

Conclusions

Continuous remimazolam infusion administered by trained gastroenterologists is a safe and effective alternative to traditional propofol sedation for GI endoscopy. It offers stable sedation, rapid recovery and high patient satisfaction, potentially reducing anesthesiology workload and improving procedural efficiency. Further studies are needed to confirm these findings in broader patient populations.
