Objectives

Narrative objectives1

In the field of gastrointestinal endoscopy, benzodiazepines are essential sedative agents for reducing patient discomfort and ensuring the safe performance of endoscopic procedures. In recent years, the short-acting benzodiazepine sedative Anerem (remimazolam) has been newly approved, and its indications in gastrointestinal endoscopic procedures have been expanding.
However, previous clinical studies have mainly focused on short-duration diagnostic or therapeutic procedures, and the clinical usefulness of remimazolam in prolonged and invasive procedures such as endoscopic submucosal dissection (ESD) has not been sufficiently evaluated. In particular, data regarding the stability of sedation, rapidity of recovery, safety, and their association with patient characteristics remain limited.
The aim of this study is to compare the clinical efficacy and safety of sedation with remimazolam and midazolam in patients undergoing ESD, and to elucidate the true pharmacological effects of these agents after adjusting for patient background factors, including alcohol consumption history, prior benzodiazepine use, and renal function.

Primary outcomes

Time to recovery from sedation (time from completion of ESD to full recovery of consciousness)

Key secondary outcomes

Stability of sedation (assessed using RASS and bispectral index (BIS) monitoring)
Completion rate of ESD (presence or absence of treatment interruption and successful resection)
Incidence of adverse events (including oxygen desaturation, hypotension, respiratory depression, and bradycardia)
Occurrence of paradoxical reactions
Physician, nurse, and patient satisfaction (assessed using a 5-point Likert scale questionnaire)

Interventions/Control_1

In this study, patients undergoing endoscopic submucosal dissection (ESD) are assigned to one of the following two intervention groups for procedural sedation:
Remimazolam group:
Sedation is performed using remimazolam (Anerem).
Sedative agents are administered according to institutional standard protocols, and dosing is adjusted to maintain an appropriate level of sedation during the procedure.

Interventions/Control_2

In this study, patients undergoing endoscopic submucosal dissection (ESD) are assigned to one of the following two intervention groups for procedural sedation:
Midazolam group:
Sedation is performed using midazolam.
Sedative agents are administered according to institutional standard protocols, and dosing is adjusted to maintain an appropriate level of sedation during the procedure.
