Does prolonged prone position affect intracranial pressure? prospective observational study employing Optic nerve sheath diameter measurements

Abstract

Although invasive methods (intraventricular and intraparenchymal monitors) are still the gold standard in the diagnosis and follow-up of increased ICP, these approaches may cause major complications, such as hemorrhage and infection [8]. Non-invasive alternative methods recommended for the assessment of ICP include the following: measurement of changes in cranial computed tomography (CT) and brain magnetic resonance imaging (MRI), transcranial doppler, tympanic membrane displacement, intraocular pressure, venous ophthalmodynamometry and ONSD [8].
