NCT01151254

Brief Summary

All patients undergoing cardiac surgery require intraoperative anesthesia and short-term postoperative sedation with anesthetic agents after the procedure when patient is in the intensive care unit (ICU). The clinical data obtained so far are concentrating on intraoperative use volatile agents (preconditioning) resulting in better postoperative cardiac function and less release of biochemical markers of myocardial damage. There are no studies investigating whether postoperative use of volatile agents (post conditioning) in cardiac surgical population is improving outcomes. The aim of the present study is to compare total intravenous anesthesia and postoperative sedation versus total volatile anesthesia and postoperative sedation in cardiac surgical population.

Outcome Measures

Primary Outcomes (1)

  • The composite primary end point of the trial will be the development of enzymatic signs of myocardial injury or MI, postoperative low output syndrome, or both. Enzymatic MI will be determined after obtaining serial measurements of troponin.

    Measurements of troponin levels will be after induction of anesthesia (baseline) and at 0, 2, 4, 8, and 24 h after arrival into the ICU.

Secondary Outcomes (4)

  • Quality of sedation

    Post ICU arrival POD 0 to discharge (2hours to on average 5-7 days until discharge)

  • Incidence of delirium

    Post ICU arrival POD 0 to discharge (2hours to on average 5-7 days until discharge)

  • Time to readiness for extubation, time to extubation

    Post ICU arrival POD 0 to discharge (2hours to on average 5-7 days until discharge)

  • Length of stay within ICU, readiness for discharge from the unit

    Post ICU arrival POD 0 to discharge (2hours to on average 5-7 days until discharge)

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients scheduled for coronary artery bypass graft surgery with good ventricular function (grade 1-2 ventricle)
  • Signed informed consent

You may not qualify if:

  • Patients undergoing valvular surgery
  • Severe kidney or liver disease (creatinine \> 2.5mg.dL-1 and bilirubin \> 2 mg.dL-1)
  • Patients with known hypersensitivity to any of the trial drugs (propofol, volatile anesthetics), e.g. propofol allergy or malignant hyperthermia (induced by volatile anesthetics)
  • Patient with poorly controlled diabetes or on oral anti-diabetic medication (inhibit preconditioning caused by volatile anesthetics)
