    Summary

    Flunitrazepam (Rohypnol) significantly reduced anxiety and improved sedation during gastro-intestinal endoscopy compared to diazepam (Valium). Patients receiving flunitrazepam also reported less vivid procedural memories and greater willingness for repeat procedures.

    Area of Science:

    • Gastroenterology
    • Pharmacology
    • Anesthesiology

    Background:

    • Gastro-intestinal endoscopy requires effective sedation and anxiolysis for patient comfort and procedural success.
    • Diazepam is a commonly used agent, but its efficacy in reducing anxiety and memory may be suboptimal.

    Purpose of the Study:

    • To compare the efficacy of flunitrazepam versus diazepam in patients undergoing gastro-intestinal endoscopy.
    • To assess the impact on patient anxiety, sedation, procedural tolerance, and memory.

    Main Methods:

    • A randomized controlled trial comparing 2 mg flunitrazepam to diazepam in patients undergoing gastro-intestinal endoscopy.
    • Patient-reported anxiety, sedation levels, procedural tolerance, and memory vividness were assessed.
    • Physiological parameters including pulse rate, respiratory rate, and blood pressure were monitored.

    Main Results:

    • Flunitrazepam significantly reduced anxiety and increased sedation compared to diazepam.
    • No significant differences were observed in intubation ease, procedural tolerance, gastric peristalsis, or pyloric state.
    • Patients receiving flunitrazepam experienced less vivid procedural memories and showed greater willingness for repeat procedures.
    • Pulse rate increased in all groups; no significant changes in respiratory rate or blood pressure were noted.

    Conclusions:

    • Flunitrazepam is a more effective agent than diazepam for reducing anxiety and improving sedation during gastro-intestinal endoscopy.
    • Flunitrazepam enhances patient experience by reducing procedural memory and increasing willingness for future procedures.
    • Flunitrazepam offers a favorable risk-benefit profile for sedation in gastro-intestinal endoscopy.
