Autoregulation of Cerebral Circulation
Autoregulation of cerebral circulation is the mechanism by which the cerebral blood flow (CBF) is maintained constant between large limits of arterial pressure. Autoregulation appears only between certain pressure limits. The specialized literature presents 2 possible mechanisms of autoregulation: myogenic reaction and metabolic regulation. Sympathetic nervous system stimulation and the antagon...
متن کاملCerebral Autoregulation in Stroke
Background and Purpose—Cerebral autoregulation may become impaired after stroke. To provide a review of the nature and extent of any autoregulation impairment after stroke and its course over time, a technique allowing repeated bedside measurements with good temporal resolution is required. Transcranial Doppler (TCD) in combination with continuous blood pressure measurements allows noninvasive ...
متن کاملCerebral autoregulation and anesthesia.
PURPOSE OF REVIEW This review will examine the recent literature on anesthesia and monitoring techniques in relation to cerebral autoregulation. We will discuss the effect of physiologic and pharmacological factors on cerebral autoregulation alongside its clinical relevance with the help of new evidence. RECENT FINDINGS Intravenous anesthesia, such as combination of propofol and remifentanil,...

Cerebral Auwregulalion in Man • Autoregulation was tested by regional blood flow (rCBF) and cardiohemodynamic measurements before and after induced systemic arterial hypertension in 16 patients with varying neurological disorders. Hypertension was induced by increasing the arterial blood pressure by an intravenous infusion of Aramine. Seven (Group 1) of the patients had a mean increase in mean ...
متن کاملDynamic cerebral autoregulation and monitoring cerebral perfusion.
Cerebral autoregulation (CA) describes the capability of the brain to maintain its flow as relatively stable over a wide rage of mean arterial pressures (MAPs), for example, from 60 to 150 mm Hg. Because the brain is encompassed in the skull, CA is vital for preventing cerebral edema and hemorrhage, as illustrated in some patients experiencing acute liver failure.1 Also, CA counteracts the effe...
