Cerebral blood flow assessed with phase-contrast magnetic resonance imaging during blood pressure changes with noradrenaline and labetalol: a trial in healthy …
Background: Adequate cerebral perfusion is central during general anesthesia. However,
perfusion is not readily measured bedside. Clinicians currently rely mainly on mean arterial
pressure (MAP) as a surrogate, even though the relationship between blood pressure and
cerebral blood flow is not well understood. The aim of this study was to apply phase-contrast
magnetic resonance imaging to characterize blood flow responses in healthy volunteers to
commonly used pharmacologic agents that increase or decrease arterial blood pressure …
