Sufentanil Infusion vs Sufentanil Bolus


Randomized single blind controlled clinical trial to test the benefit of sufentanil infusion over bolus dosing to reduce time to extubation and reduced length of ICU stay.

Full Title of Study: “Sufentanil Infusion vs Sufentanil Bolus and Time to Extubation During Routine Cardiac Surgery”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Single (Participant)
  • Study Primary Completion Date: February 1, 2022


  • Drug: Sufentanil Infusion
    • Intra-operative sufentanil infusion
  • Drug: Sufentanil Bolus
    • Intra-operative sufentanil bolus

Arms, Groups and Cohorts

  • Active Comparator: Sufentanil Bolus
  • Experimental: Sufentanil Infusion

Clinical Trial Outcome Measures

Primary Measures

  • Time to extubation
    • Time Frame: 60 minutes
    • We will determine if sufentanil infusion administration intra-operatively during routine cardiac surgery will decrease time to extubation.

Secondary Measures

  • Plasma concentration
    • Time Frame: intra-operative
    • 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.
