OBJECTIVE To compare dynamic and static responses of cerebral blood flow to sudden or slow changes in arterial pressure in severe traumatic brain injury (TBI) patients. DESIGN Prospective study. PATIENTS AND METHODS We studied 12 severe TBI patients, age 16-63 years, and median GCS 6. We determined the dynamic cerebral autoregulation: response of cerebral blood flow velocity to a step blood pressure drop, and the static cerebral autoregulation: change in cerebral blood flow velocity after a… CONTINUE READING
