Brief summary

The goal of this clinical trial is to compare two sedation regimens-remimazolam and midazolam-for colonoscopy in adult patients with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. The main questions it aims to answer are: * Does remimazolam provide patient satisfaction that is non-inferior to midazolam during colonoscopy? * Does remimazolam allow faster recovery and discharge readiness compared to midazolam? Researchers will compare sedation with remimazolam plus fentanyl to sedation with midazolam plus fentanyl to see if remimazolam improves patient experience and procedural efficiency. Participants will: * Receive either remimazolam or midazolam, each combined with fentanyl, during their scheduled colonoscopy * Complete a short questionnaire to rate their satisfaction after the procedure * Be assessed for recovery using a standardized discharge score at 10 and 20 minutes after the procedure

Interventions

DRUGIntravenous remimazolam (5 mg initially, with optional 2.5 mg boluses) plus fentanyl (100 mcg) for procedural sedation.

\- Remimazolam + Fentanyl IV fentanyl 100 mcg is given first, followed after 1 minute by IV remimazolam 5 mg over 1 minute. Additional 2.5 mg boluses may be given every 2 minutes as needed. Colonoscopy starts 1 minute after sedation. Vital signs are monitored throughout.

DRUGIntravenous midazolam (3 mg initially, with optional 3 mg boluses) plus fentanyl (100 mcg) for procedural sedation.

\- Midazolam + Fentanyl (≤1000 caratteri) IV fentanyl 100 mcg is given first, followed after 1 minute by IV midazolam 3 mg over 1 minute. Additional midazolam may be administered based on clinical judgment. Colonoscopy starts 1 minute after sedation. Vital signs are monitored throughout.

Intervention model description

Participants were assigned to sedation with either remimazolam or midazolam based on a pragmatic, time-based allocation schedule (i.e., all procedures during a given week used the same sedation regimen). This approach was chosen to ensure feasibility and avoid operator or patient selection bias. No individual-level randomization was performed.

Design outcomes

Primary

MeasureTime frameDescription
Patient satisfactionImmediately post-procedureProportion of patients reporting at least satisfied with sedation (Likert scale 1-4, 3 or 4 points)

Secondary

MeasureTime frameDescription
Dischatge readiness 20'20 minutes post-procedureProportion of patients ready for discharge (PADSS ≥9)
Patient high satisfactionImmediately post-procedureProportion reporting very satisfied (Likert scale 1-4, 4 points)
Incidence of treatment-emergent adverse eventsThroughout the observation period (i.e., until discharge)Proportion of patients experiencing any of the following adverse events (occurring after the administration of the study drug): * Desaturation: peripheral oxygen saturation (SpO₂) below 90% * Tachycardia: heart rate greater than 100 bpm * Bradycardia: heart rate less than 50 bpm * Hypotension: systolic blood pressure below 90 mmHg
Discharge readiness 10'10 minutes post-procedureProportion of patients ready for discharge (PADSS ≥9)
Maximum net benefit10 minutes post-procedureProportion of patients reportinng very satisfied with sedation (Likert scale 1-4, 4 points) + ready for discharge (PADSS ≥9)

Other

MeasureTime frameDescription
Endoscopy metrics - cecal intubation rateDuring procedurePercentage of procedures where the endoscope successfully reaches the cecum and can be visually confirmed by inspecting the appendiceal orifice
Endoscopy metrics - cecal intubation timeDuring procedureTime from the insertion of the colonoscope tip into the anal verge until reaching the cecal base
