The Lower Limit of Cbf Autoregulation
Copyright © 2013 International Anesthesia Research Society PERSPECTIVE I have committed considerable professional time to anesthesia for neurologic surgery. That commitment has caused me to hear a great deal related to neuroanesthesia. I have been asked by faculty colleagues in anesthesia, “What do you suppose might have gone wrong during that case yesterday?” I have listened to American Board ...
متن کاملLower limit of cerebral blood flow autoregulation in experimental renovascular hypertension in the baboon.
The effect of chronic renovascular hypertension on the autoregulation of cerebral blood flow was studied in anesthetized baboons. Cerebral blood flow was measured by the intracarotid 133Xe clearance method. Six baboons with renal hypertension of 8-12 weeks' duration were compared with six normotensive controls. The lower limit of autoregulation was determined following controlled hemorrhage. In...
متن کاملChanges in the intracranial rheoencephalogram at lower limit of cerebral blood flow autoregulation.
Cerebral blood flow (CBF) reactivity monitoring is an appropriate primary parameter to evaluate cerebral resuscitation due to a systemic or regional cerebral injury leading to possible irreversible brain injury. Use of the electrical impedance method to estimate CBF is rare, as the method's anatomical background is not well understood. Use of intracranial rheoencephalography (iREG) during hemor...
متن کاملUpper Limit of Autoregulation of Cerebral Blood Flow in the
The upper limit of autoregulation of cerebral blood flow was studied in ten young baboons. Blood pressure was increased by infusing angiotensin, and cerebral blood flow was measured by the intracarotid 133 xenon injection method. Autoregulation was maintained until blood pressure was 30-40% above resting values. At this blood pressure level, cerebrovascular resistance reached a maximum. Any add...
متن کاملTranscranial Doppler is valid for determination of the lower limit of cerebral blood flow autoregulation.
BACKGROUND AND PURPOSE This study validates transcranial Doppler sonography (TCD) for determination of the lower limit of cerebral blood flow (CBF) autoregulation and establishes a relation between global CBF and mean flow velocity (Vmean) in the middle cerebral artery. METHODS Relative changes in CBF and in Vmean were compared in 12 normal volunteers (2 women and 10 men; median age, 30 years...
