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 کاملFunctional laser speckle imaging of cerebral blood flow under hypothermia.
Hypothermia can unintentionally occur in daily life, e.g., in cardiovascular surgery or applied as therapeutics in the neurosciences critical care unit. So far, the temperature-induced spatiotemporal responses of the neural function have not been fully understood. In this study, we investigated the functional change in cerebral blood flow (CBF), accompanied with neuronal activation, by laser sp...
متن کاملNitric oxide in the nucleus raphe magnus modulates cutaneous blood flow in rats during hypothermia
Objective(s): Nucleus Raphe Magnus (NRM) that is involved in the regulation of body temperature contains nitric oxide (NO) synthase. Considering the effect of NO on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. Materials and Methods: To this end, tail blood flow of male Wistar rats was measured by laser doppler following the induction of ...
متن کاملCerebral blood flow during carotid endarterectomy.
Cerebral blood flow (CBF) was measured during 28 carotid endarterectomies in 25 patients, by injection of 133Xe into the exposed internal carotid artery (ICA). Twenty-three patients had episodic cerebral or retinal ischemia and five had neurologic deficits before operation. Initial CBF values were variable. Increases of PaC02 caused CBF to increase in four of six patients, to increase slightly ...
متن کاملCerebral blood flow velocity during neonatal seizures.
AIM To determine if cerebral blood flow velocity increases during all types of neonatal seizure, and whether the effect is due solely to an increase in blood pressure, transmitted to the cerebral circulation when autoregulation is impaired. METHODS Seizures were diagnosed in 11 high risk neonates using cotside 16 channel video-EEG polygraphy. EEG, cerebral blood flow velocity (CBFV) using tra...
