متن کاملCerebral complications following induced hypotension.
Over an 8-year period (1977-1984), 1,802 otorhinolaryngological procedures were performed under controlled hypotension. Four patients showed symptoms of cerebral damage post-operatively. One patient had pre-operative unrecognized stenosis of the internal carotid artery, another a hypoplastic vertebral artery. In this female patient, the head had been strongly rotated to the side to expose the s...
متن کاملEffects of Hemorrhagic Hypotension on the Cerebral Circulation
The effects of graded hemorrhagic hypotension on electrocortical function was investigated in 12 cats anesthetized with a-chloralose. Cerebral function was assessed both in terms of spontaneous activity (EEG) and the somatosensory evoked response. No significant changes in the EEG trace or in the amplitude of the positive/negative waves of the primary evoked response were observed at mean arter...
متن کاملEffects of hemorrhagic hypotension on the cerebral circulation. III. Neuropathology.
A neuropathological examination was made of 15 cats anesthetized with alpha-chloralose, subjected to a stepwise reduction in mean arterial pressure by graded hemorrhagic hypotension. Five animals were sacrificed by perfusion-fixation at a mean arterial pressure of 75 mm Hg, 5 at a mean pressure of 35 mm Hg and 5 at 25 mm Hg. Ischemic brain damage was seen in only 5 animals, one sacrificed at a ...
