Brief summary

Study to evaluate the efficacy and safety of remimazolam in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration Primary Outcome Evaluate and compare the success of the procedure in patients undergoing EBUS-TBNA (Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration) when administered with remimazolam in the experimental group, versus Real world midazolam (Control Group 1), and On label midazolam (Control Group 2). Secondary Outcome In patients undergoing EBUS-TBNA, compare the following aspects when administered with remimazolam in the experimental group versus Real world midazolam (Control Group 1) and On label midazolam (Control Group 2): Procedure start time, Time taken to achieve full alertness, Need for flumazenil administration, Total dose of fentanyl used, Scale of coughing/discomfort/convenience, Changes in vital signs, Complications related to the procedure.

Design outcomes

Primary

MeasureTime frameDescription
Procedural success during EBUS-TBNA (composite outcome)Up to the end of the procedure (up to 1 hour)Success of the bronchoscopy procedure, Completion of the bronchoscopy procedure, No requirement for a rescue sedative medication, In the case of remimazolam and placebo, no requirement for more than 5 top-ups of study medication within any 15 minute period; in the case of midazolam, no requirement for more than 3 doses in any 12 minute window

Secondary

MeasureTime frameDescription
Time to start of procedure after administration of the first dose of study medicationTime from administration of the first dose of study medication to the start of procedure (MOAA/S ≤3) (up to 1 hour)Modified Observer's Assessment of Alertness and Sedation (MOAA/S)≤3 MOAA/S scores: 5 = Responds readily to name spoken in normal tone \[alert\], 4 =Lethargic response to name spoken in normal tone, 3 = Responds only after name is called loudly and/or repeatedly, 2 = Responds only after mild prodding or shaking, 1 = Responds only after painful trapezius squeeze, 0 = Does not respond to painful trapezius squeeze. MOAA/S scores were assessed by the investigators.
Time taken to achieve full alertness after the procedureTime from end of the procedure to first of three consecutive MOAA/S scores =5 (up to 1 hour)MOAA/S=5 MOAA/S scores: 5 = Responds readily to name spoken in normal tone \[alert\], 4 =Lethargic response to name spoken in normal tone, 3 = Responds only after name is called loudly and/or repeatedly, 2 = Responds only after mild prodding or shaking, 1 = Responds only after painful trapezius squeeze, 0 = Does not respond to painful trapezius squeeze. MOAA/S scores were assessed by the investigators.
Requirement for flumazenil dosage during the procedureFrom the end of procedure to discharge of bronchoscopy room (up to 1 hour)If MOAA/S score 5 is not reached after bronchoscopy, flumazenil will be administered. Total amount of flumazenil dosage during the procedure is measured. MOAA/S scores: 5 = Responds readily to name spoken in normal tone \[alert\], 4 =Lethargic response to name spoken in normal tone, 3 = Responds only after name is called loudly and/or repeatedly, 2 = Responds only after mild prodding or shaking, 1 = Responds only after painful trapezius squeeze, 0 = Does not respond to painful trapezius squeeze. MOAA/S scores were assessed by the investigators.
Total fentanyl doseFrom the start of procedure to the end of procedure (up to 1 hour)Total amount of fentanyl during the procedure
Complications related to the procedureUp to 1 monthProcedure related complications during 1 month follow up
Changes in blood pressureFrom the start of procedure to the end of procedure (up to 1 hour)Changes of blood pressure (mmHg) assessed by 5 minutes
Changes of heart rateFrom the start of procedure to the end of procedure (up to 1 hour)Changes of heart rate (rates/minutes) assessed by 5 minutes
Changes in respiration rateFrom the start of procedure to the end of procedure (up to 1 hour)Changes of respiration rate (rates/minutes) assessed by 5 minutes
Scale of coughing/discomfort/inconvenienceAfter the end of procedure (up to 1 hour)Coughing/discomfort/convenience visual analogue scale (Patients mark a point on a straight line corresponding to their perception of the severity of the cough, discomfort, and inconvenience. VAS ranges 0-100, with 0 representing minimal severity and 100 representing maximal severity)
