Bronchoscopy Clinical Trial
Official title:
Safety and Efficacy of Remimazolam Compared With Midazolam During Bronchoscopy: A Single Center, Randomized Controlled Study
Objectives: Although remimazolam is an ultra-short-acting benzodiazepine with a shorter elimination half-life and faster recovery time than midazolam, studies evaluating its safety and efficacy during bronchoscopy are limited. This study compared the safety and efficacy of remimazolam with that of midazolam for bronchoscopy. Design: A single-center, prospective randomized parallel-group study Setting: Chungbuk National University Hospital, April 2022-June 2023. Participants: One hundred patients were enrolled; 51 were randomly assigned to the midazolam group and 49 to the remimazolam group. Respiratory nurse specialists performed the randomization. Interventions: Oral and laryngeal anesthesia was induced using a 4% lidocaine nebulizer prior to sedation. The vocal cords and lower airway tract were anesthetized. Patients aged <60 years or weighing >50 kg received 3 mg intravenous midazolam or 5 mg remimazolam. Patients aged ≥60 years or weighing <50 kg received 2 mg intravenous midazolam or 3 mg remimazolam. Bronchoscopy was performed under adequate sedation (MOAA/S≤3) Main outcome measures: The primary outcome was the time from the end of the procedure to full alertness. Secondary outcomes were procedural time parameters, satisfaction profiles, and adverse effects.
