Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Drug: remimazolam
For patients undergoing elective procedural sedation or sedation with regional anaesthesia. Anticipated duration of the procedure is up to one hour.
Bispectral Index (BIS) monitoring using sensors which are placed on the forehead of participants is used to measure the participant's level of consciousness and with that to monitor the depth of anaesthesia.
The examiner will use Modified Observer's Alertness/Sedation scale (MOAA/S) and Richmond Agitation-Sedation Scale (RASS) values to measure the agitation or sedation level of a participants.
The examiner will measure MOAA/S and RASS values at the beginning of the procedure.
Remimazolam will be started with the loading dose of 5mg intravenously over a 1-minute time period. After the loading dose, the continuous intravenous infusion of remimazolam will start, which will be titrated to maintain the target Bispectral Index (BIS) values of 60-80 during procedure, which indicates an adequate depth of sedation.
During the entire procedure, BIS, MOAA/S and RASS values will be measured and recorded at 5-minute intervals, and depending on the obtained values, the remimazolam infusion rate will be corrected. At the end of the procedure, after stopping the administration of the drug, the time required from the end of the infusion to the complete recovery of consciousness will be measured.

Outcomes
Primary outcome [1] 333258 0
Primary outcome is to determine the necessary range of continuous dose of remimazolam (mg/kg/h) for procedural sedation or sedation with regional anaesthesia. Sedation will be determined by evaluation of BIS, MOAA/S and RASS scores during procedure. All measurements and the dose of remimazolam will be assessed together as a composite primary outcome.
Timepoint [1] 333258 0
The primary outcome measurements will be assessed every 5 minutes from the start of sedation till complete recovery of consciousness.
Secondary outcome [1] 416382 0
Side effects registered during continuous infusion of remimazolam will be assessed by standard monitoring. Hypotension will be assessed using sphygmomanometer, bradycardia will be assessed with ECG monitoring and drop in saturation will be assessed using pulse oximeter.
Timepoint [1] 416382 0
Blood pressure measurements will be assessed every 5 minutes from the start of sedation till complete recovery of consciousness. Heart rate and saturation measurements will be assessed continuously from the start of sedation till complete recovery of consciousness.

Safety
Statistical methods / analysis
50 patients will be included in the study. The number of patients is determined by the availability and price of remimazolam. The dose required to achieve and maintain an adequate level of sedation will be analyzed for each patient. Demographic and clinical data will be recorded on a standardized form. Recorded demographic data will be: age, sex, height and weight. Recorded clinical data will be: ASA status, heart rate, mean arterial pressure, oxygen saturation, BIS score, MOAA/S and RASS scale. The rate of infusion of Remimazolam will be recorded.

Summary
Brief summary
The purpose of the research is to determine the necessary range of continuous doses of remimazole for procedural sedation or sedation with regional anesthesia as an alternative to other, less hemodynamically and respiratory safe drugs that are currently used, propofol and midazolam.
Research hypothesis: A continuous dose of remimazolam adjusted for the body weight and height of the patient is a sufficient and hemodynamically and respiratory safe alternative to currently used drugs in doses comparable to bolus doses.
