Outcome Measures

Primary Outcomes (1)

  • Total amount of the vasopressor phenylephrine that is needed to maintain blood pressure above 60 mmHg during 10 minutes of Cardiopulmonary bypass.

    10 minutes

Secondary Outcomes (1)

  • 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.

    10 minutes

Study Arms (2)

Sevoflurane

ACTIVE COMPARATOR

Administration of the volatile anesthetic Sevoflurane.

Drug: Sevoflurane and isoflurane

Isoflurane

ACTIVE COMPARATOR

Administration of the volatile anesthetic Isoflurane.

Drug: Sevoflurane and isoflurane

Interventions

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.

Also known as: Sevorane/isoflurane

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • competent adult patients (18 years or older)undergoing elective coronary artery bypass grafting with the use of the cardiopulmonary bypass.

You may not qualify if:

  • Patients undergoing valve surgery or combined surgical procedures (e.g. coronary artery bypass grafting in combination with valve reconstruction.
  • uncontrolled hypertension
