- Primary Outcome Measures
Name Time Method The primary outcome is the level of agreement between OMT and RASS at all clinical RASS levels achieved while sedated in intensive care[RASS scores will be taken at 30 minute intervals, after emergence from anaesthesia until extubation in the ICU.]
- Secondary Outcome Measures
Name Time Method Predictive capacity of OMT vs BIS to differentiate specific clinical events: induction, intubation, skin incision, bypass on and off, sternal closure and transfer to ICU.<br>[OMT and BIS measurements will be recorded continuously prior to anaesthesia, during induction, re-emergence and until extubation in the ICU.];Determine the nature and strength and of the relationship between OMT and BIS under differing anesthetic agents and during hypothermia<br><br>[From prior to anaesthesia until re-emergence from anaesthesia];Ease of OMT application and monitoring on visual scale of 1-10<br>[From prior to induction of anaesthesia to completion of surgery];Bedside nurse satisfaction with OMT on a visual scale 1-10<br>[At completion of monitoring of OMT at the bedside.]
