Cerebral blood flow and cerebral oxygen consumption during hypothermia.
C URRENTLY there is widespread interest in the physiologic effects of cold, and in the use of hypothermia with surgery (I, 2). Although no gross neurologic derangements have been observed following the application of this technique in man and experimental animals (3, 4), it seemed appropriate that a special study be made of the effects of hypothermia on cerebral physiology. Cerebral blood flow,...
متن کاملCerebral blood flow and metabolism during exercise.
During exercise regional cerebral blood flow (rCBF), as blood velocity in major cerebral arteries and also blood flow in the internal carotid artery increase, suggesting an increase in blood flow to a large part of the brain. Such an increase in CBF is independent of the concomitant increase in blood pressure but is modified by the alteration in arterial carbon dioxide tension (PaCO(2)). Also, ...
متن کاملBrain oxygenation and metabolism during selective cerebral perfusion in neonates.
OBJECTIVE To investigate the possible neuroprotective effects of selective cerebral perfusion (SCP) during deep hypothermic circulatory arrest on brain oxygenation and metabolism in newborn piglets. METHODS Newborn piglets 2-4 days of age, anesthetized and mechanically ventilated, were used for the study. The animals were placed on cardiopulmonary bypass, cooled to 18 degrees C and put on SCP...
متن کاملMonitoring Cerebral Blood Flow , Oxygen , and Glucose Metabolism
More accurate methods for monitoring cerebral blood flow, oxygen, and glucose metabolism with results of their application in human volunteers are described. Subjects with various types of cerebral vascular disease showed decreased cerebral blood flow and oxygen and glucose metabolism but anaerobic glycolysis appeared to be increased. Inhalation of 100% oxygen decreased anaerobic glycolysis, an...
متن کاملCerebral oxygen extraction, oxygen consumption, and regional cerebral blood flow during the aura phase of migraine.
BACKGROUND AND PURPOSE The aura phase of migraine is associated with focal blood flow changes, but it has been largely unknown whether these changes are correlated to changes in the cerebral metabolism. METHODS Eight patients required carotid angiography for evaluation of transient neurological attacks. Cerebral blood flow (CBF) results, angiography, and clinical observations subsequently sug...
