Norepinephrine vs Phenylephrine During General Anesthesia
Sponsor: University of California, San Francisco
Summary
50 million patients undergo surgery each year in the United States. Postoperative mortality is considered the third leading cause of death worldwide. Hypotension during surgery have been linked to increased postoperative morbidity and mortality. Episodes of hypotension during surgery are associated with an increased risk of acute kidney injury, stroke, cardiac events and death. Treating or preventing hypotension during general anesthesia and major surgery was found to improve outcomes. At this time, it is unclear what is the best vasopressor to maintain blood pressure during surgery under general anesthesia. With this pilot pragmatic trial, the investigators will explore the impact of norepinephrine (NE) or phenylephrine (PE) on post-operative events in patients undergoing major surgery with general anesthesia and needing vasopressors infusion to maintain their systemic arterial pressure.
