Blood pressure and cerebrospinal fluid pressure studies during lumbar air encephalography.
Blood pressure and cerebrospinal fluid pressure changes were studied during lumbar air encephalography under general anaesthesia. Two anaesthetic techniques were used. In one group spontaneous respiration with nitrous oxide, oxygen and halothane was used and in the other controlled ventilation with nitrous oxide and oxygen was maintained. Larger falls in blood pressure, on sitting up, were seen...
متن کاملAlterations in lumbar cerebrospinal fluid protein during air encephalography.
A significant fall occurred in the protein content of successive specimens of lumbar cerebrospinal fluid (C.S.F.) withdrawn during the course of air encephalography in 57% of cases. No correlation was found between the fall in the protein concentration and the total volume of air injected or the total volume of C.S.F. withdrawn, but the size of the fall was greater when the initial lumbar C.S.F...
متن کاملThe effect of nitrous oxide on the cerebrospinal fluid pressure during encephalography.
Cerebrospinal fluid pressure was measured in twenty-three patients undergoing encephalography. Three different programmes were followed to determine the effect of nitrous oxide on intracranial pressure with and without injection of air and nitrous oxide into the theca. In every case the initial c.s.f. pressure remained unchanged when nitrous oxide was used for encephalography, while it increase...
متن کاملCerebrospinal fluid pressure.
The cerebrospinal fluid pressure at the foramen of Monro in man in the recumbent position is less than 100 mm water relative to atmospheric pressure. The oscillations in the pressure wave due to respiration and cardiac pulsation vary with the actual pressure and increase as the overall pressure rises. In man lying horizontally the oscillation at the foramen of Monro is usually less than 50 mm w...
متن کاملCerebrospinal Fluid Pressure and Glaucoma
Eyes with normal-pressure glaucoma and those with high-pressure glaucoma can show a similar optic nerve head appearance, while eyes with vascular optic neuropathies show a markedly different optic disc appearance. Factors in addition to intraocular pressure (IOP) may thus play a role in the pathogenesis of glaucomatous optic neuropathy. Clinical and experimental studies showed that (1) physiolo...
