Primary
| Measure | Time frame |
|---|---|
| Difference in the propofol dose required to achieve BIS 50 in adults presenting for elective non-cardiac surgeries when active noise cancellation is provided versus when it is not as part of CLADS based inductionTimepoint: at the end of induction (first instance of BIS 50) | — |
Secondary
| Measure | Time frame |
|---|---|
| Estimated effect site concentration of propofol at induction Timepoint: at the end of induction (first instance oF BIS 50);Time to achieve BIS-50 on induction Timepoint: time from start of induction at BIS 100 to BIS 50;Total intraoperative dose of propofol (mg/kg/hr) Timepoint: propofol dose used from starting of induction to the end of surgery;Frequency of post induction hypotension Timepoint: till 10 minutes after induction;Rescue dose of phenylephrine and mephentermine used Timepoint: from induction to end of surgery;Percentage of time spent between BIS 40-60Timepoint: from induction to stopping propofol;Recovery timeTimepoint: stop of infusion to extubation;PONV scores Timepoint: at 30 mins,6th, 12th, 24th hour postopearatively;Postoperative NRS pain scoresTimepoint: at 30 mins, 6th, 12th, 24th hour of postoperative period;Postoperative deliriumTimepoint: at 30 mins, 6th, 12th, 24th hour postoperatively | — |
