Cerebrospinal 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...
متن کاملEndothelin and aneurysmal subarachnoid haemorrhage: a study of subarachnoid cisternal cerebrospinal fluid.
Endothelin (ET) is considered one of the most potent vasoconstrictor polypeptides; several experimental studies have suggested its possible role in the pathogenesis of arterial vasospasm after subarachnoid haemorrhage (SAH). Previously reported data on plasma and CSF levels of endothelin in patients with a diagnosis of SAH have been controversial. Cisternal endothelin CSF levels and the possibi...
متن کاملEvaluation of ventriculo-cisternal perfusion model as a method to study cerebrospinal fluid formation.
AIM To evaluate ventriculo-cisternal perfusion as a method for measuring cerebrospinal fluid formation rate, calculated by means of the Heisey et al equation. Method. All experiments were carried out on anesthetized domestic cats fixed in the sphinx position in a stereotaxic frame. Ventriculo-cisternal perfusion was used at an intracranial pressure of -10 cm H2O at different perfusion rates (32...
متن کاملEffects of althesin on cerebrospinal fluid pressure.
Changes in cerebrospinal fluid pressure after induction of anaesthesia with Althesin were recorded in 21 volunteer patients who had no abnormality of the central nervous or cardiorespiratory systems. In patients who breathed spontaneously, cerebrospinal fluid pressure fell by 45% at 1 min after intravenous injection of Althesin 0.1 ml/kg. It returned almost to preinduction levels by 12 min Duri...
