Respiratory Disease Clinical Trial
Official title:
Total Intravenous Anesthesia for Rigid Bronchoscopy - Remimazolam Versus Propofol: a Prospective Randomized Controlled Trial
Rigid bronchoscopy usually requires deep general anesthesia, but the duration of the procedure is relatively short. Remimazolam, a recently developed anesthetics, showed faster recovery from anesthesia and stable hemodynamics compared to propofol, the most popular anesthetics. However, few studies have investigated the usefulness of remimazolam for rigid bronchoscopy. Therefore, the investigators compared the usefulness of propofol and remimazolam in total intravenous anesthesia for rigid bronchoscopy.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | The duration of emergence after rigid bronchoscopy | The time interval between the end of anesthetics infusion and the extubation | From the end of anesthetics infusion to the extubation, an average of 10 minutes | |
Secondary | The duration of induction before rigid bronchoscopy | Time interval between the start of anesthetics infusion and loss of responsiveness | From the start of anesthetics infusion to the loss of responsiveness, an average of 5 minutes | |
Secondary | Awareness during general anesthesia | Whether patient experience awareness during general anesthesia. Awareness during general anesthesia will be assessed with the use of a modified Brice questionnaire. 30 minutes after the arrival at a postanesthesia care unit, a study staff who is blind to the allocation of patients will interview the patient. | From the start of anesthetics infusion to the extubation, an average of 30 minutes | |
Secondary | Use of vasoactive medication during rigid bronchoscopy | Whether vasoactive medication is needed to maintain vital signs within 20% of baseline | From the start of anesthetics infusion to the extubation, an average of 30 minutes |
