Dynamic 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...

متن کاملFaster recovery of cerebral perfusion in SOD1-overexpressed rats after cardiac arrest and resuscitation.
BACKGROUND AND PURPOSE Protracted hypoperfusion is one of the hallmarks of secondary cerebral derangement after cardiac arrest and resuscitation (CAR), and reactive oxygen species have been implicated in reperfusion abnormalities. METHODS Using transgenic (Tg) rats overexpressing copper zinc superoxide dismutase (SOD1), we investigated the role of this intrinsic antioxidant in the restoration...
متن کاملCerebral circulation after cardiac arrest. Microangiographic and protein tracer studies.
The effects of ventricular fibrillation and subsequent resuscitation on the microcirculation of the verebral cortex were studied with microangiographic and fluorescent protein tracer techniques. Immediately after revival, a transient period of impaired cerebral perfusion occurred before complete recovery from circulatory arrest was obtained. A circulatory arrest of longer than ten minutes, foll...
متن کاملModern and Evolving Understanding of Cerebral Perfusion and Autoregulation.
Key Points Significant changes in anesthetic management for optimizing cerebral perfusion have occurred over the past 5 to 10 years. Perhaps the most important of these changes has been a reinterpretation of older autoregulation studies that have resulted in raising the lower limit of autoregulation to approximately 70 mm Hg to 80 mm Hg, and not the previously used 60 mm Hg. Tremendous variabil...
