Design outcomes

Primary

MeasureTime frame
To compare the percentage of valid CLADS time Bispectral Index (BIS) values remain within the target range 60 10 during sedation maintained by Closed Loop Anaesthesia Delivery System for propofol when supplemented with dexmedetomidine versus ketamine.Timepoint: During the ERCP procedural sedation

Secondary

MeasureTime frame
Percentage of the valid CLADS time for which BIS remains in the range of 60 5.Timepoint: During the ERCP procedural sedation;Performance errorTimepoint: During the ERCP procedural sedation;Median performance errorTimepoint: During the ERCP procedural sedation;Median absolute performance errorTimepoint: During ERCP procedural sedation;Global scoreTimepoint: During the ERCP procedural sedation;WobbleTimepoint: During the ERCP procedural sedation;Hemodynamic stability any fall or increase in blood pressure or heart rate 25% of the baseline parametersTimepoint: During the ERCP procedural sedation;Duration for which heart rate or blood pressure remains 25% of the baselineTimepoint: During the ERCP procedural sedation;Episodes of apnea requiring intervention to maintain the airwayTimepoint: During the ERCP procedural sedation;Total propofol used (mg and mg/kg)Timepoint: During the ERCP procedural sedation;Plasma target concentration of propofol (Marsh model) required to achieve BIS 60Timepoint: During the ERCP procedural sedation;Plasma concentration of propofol required to achieve a BIS of 60Timepoint: During the ERCP procedural sedation;Total dexmedetomidine used ( g and g/kg)Timepoint: During the ERCP procedural sedation;Total ketamine used in mg and mg/kgTimepoint: During the ERCP procedural sedation;Time to awakening in minutesTimepoint: During the ERCP procedural sedation;Patient discomfort during the procedureTimepoint: During the ERCP procedural sedation;Need to give additional intravenous bolus of the study drugsTimepoint: During the ERCP procedural sedation
