PRIMARY outcome

Timeframe: Amount of time in minutes from procedure finish to time of extubation, up to 800 minutes.

Population: The participant number represent the number of participant whom made it to this portion of the study.

We will determine if sufentanil infusion administration intra-operatively during routine cardiac surgery will decrease time to extubation from OR stop data collection time point by 60 minutes compared to sufentanil bolus administration.

Outcome measures

Measure	Sufentanil Bolus n=24 Participants Sufentanil Bolus: Intra-operative sufentanil bolus	Sufentanil Infusion n=24 Participants Sufentanil Infusion: Intra-operative sufentanil infusion
Time to Extubation	230.5 Minutes Interval 52.0 to 794.0	242.4 Minutes Interval 58.0 to 691.0

SECONDARY outcome

Timeframe: Lab concentration is drawn when patient arrives to ICU, an average of 1 hour after procedure.

Population: Lab concentration was measured on arrival to ICU. Not all subjects had this lab available, thus the inconsistency of numbers from the participant flow module.

We will determine if sufentanil infusion administration intra-operatively during routine cardiac surgery will result in a lower plasma concentration of sufentanil at time of arrival to ICU and if the plasma concentration correlates with time to extubation.
