The Effect of Vasopressors on Cerebral Oxygentaion During Off Pump CABG

The Effect of Phenylephrine, Norepinephrine and Vasopressin on Cerebral Oxygentaion During Off Pump CABG: A Pilot Study

The purpose of this study is to analyze the changes in cerebral oxygen saturation during the use of three vasopressors, phenylephrine, norepinephrine, and vasopressin, which are currently used during coronary artery bypass grafting.

Inclusion Criteria:

• Patients undergoing off pump coronary artery bypass.

Exclusion Criteria:

• Patient refusal
• Preoperative vasopressor use
• Preoperative mechanical circulatory support
• Concurrent cerebrovascular or head and neck surgery
• Technical difficulty of measuring brain oxygen saturation
• Redo coronary artery bypass surgery
