10 Which statement about Cerebral Physiology is correct
(A) The brain has a high metabolic rate and receives approximately 15% of cardiac output. Under normal circumstances, cerebral blood flow (CBF) is approximately 50 mL/100 g/min. Gray matter receives 80% and white matter receives 20% of this blood flow. Page
(B) All volatile anesthetics suppress the cerebral metabolic rate (CMR) and can produce burst suppression of the electroencephalogram(EEG).
(C) Barbiturates, Propofol, Ketamine, volatile anesthetics, Etomidate and xenon have neuroprotective efficacy and can reduce ischemic cerebral injury in experimental models.
(D) Vasopressors can increase CBF directly
(E) All of above are correct
