Sufentanil Infusion vs Sufentanil Bolus

This study will compare Sufentanil bolus vs infusion and analyze which has a faster extubation time in participants who undergo routine cardiac surgery. The hypothesis is that routine cardiac surgery patients receiving sufentanil infusion will have a lower sufentanil concentration at the end of surgery and have a shorter time to extubation than participants receiving sufentanil bolus dosing even with similar total doses of sufentanil. The intervention will be Sufentanil infusion during surgery and evaluations will include Sufentanil blood concentrations, ICU and hospital length of stay and re-intubation rate. We will follow up with the participants through their ICU stay (primary objective) and hospital length of stay (secondary objective).
