Primary Outcome Measures:
  • Total amount of the vasopressor phenylephrine that is needed to maintain blood pressure above 60 mmHg during 10 minutes of Cardiopulmonary bypass. [ Time Frame: 10 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Mean blood pressure throughout the 10 minute periods, the need for a stronger vasopressor (norepinephrine) and the inability to keep mean blood pressure below 75 mmHg at MAC 0.6. [ Time Frame: 10 minutes ] [ Designated as safety issue: No ]

Estimated Enrollment: 35
Study Start Date: May 2009
Estimated Study Completion Date: December 2009
Estimated Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Sevoflurane
Administration of the volatile anesthetic Sevoflurane.
Drug: Sevoflurane and isoflurane
Patients will be randomized to a 10 minute treatment with isoflurane, followed by a wash-out period, followed by a 10 minute treatment with sevoflurane, or the other way round.
Other Name: Sevorane/isoflurane
Active Comparator: Isoflurane
Administration of the volatile anesthetic Isoflurane.
Drug: Sevoflurane and isoflurane
Patients will be randomized to a 10 minute treatment with isoflurane, followed by a wash-out period, followed by a 10 minute treatment with sevoflurane, or the other way round.
Other Name: Sevorane/isoflurane

Detailed Description:

In modern anesthesia a variety of volatile anesthetics is available. In cardiac anesthesiology both isoflurane and sevoflurane are frequently used. At present the number of studies comparing the influence of isoflurane and sevoflurane on blood pressure and systemic vascular resistance is limited. Moreover, the results presented in the available literature are inconsistent. The decision as to which of both volatiles should be used during cardiac surgery is not evidence-based, but is based on personal preference of the anesthesist. The most reliable way to compare the effects of isoflurane and sevoflurane on blood pressure and systemic vascular resistance is a randomized controlled trial in patients during Cardiopulmonary bypass (CPB).
