Perioperative Noninvasive Assessment of Intracranial Tension by Ultrasonographic Monitoring of Optic Nerve Sheath Diameter: Our Experience
Intracranial hypertension occurs with significant regularity during general anaesthesia. Although majority of times it goes unrecognised and does not cause significant perioperative morbidity, its importance cannot be ignored especially in patients with intracranial pathologies. The intracranial tension can rise significantly during prolonged extreme positioning like steep trendelenburg positio...
متن کاملNoninvasive and quantitative intracranial pressure estimation using ultrasonographic measurement of optic nerve sheath diameter
We aimed to quantitatively assess intracranial pressure (ICP) using optic nerve sheath diameter (ONSD) measurements. We recruited 316 neurology patients in whom ultrasonographic ONSD was measured before lumbar puncture. They were randomly divided into a modeling and a test group at a ratio of 7:3. In the modeling group, we conducted univariate and multivariate analyses to assess associations be...
متن کاملsonographic optic nerve sheath diameter as a screening tool for detection of elevated intracranial pressure
introduction: timely diagnosis and treatment of post traumatic, elevated intracranial pressure (eicp), could reduce morbidity and mortality, as well as improve patients’ outcome. this study is trying to evaluate the diagnostic accuracy of sonographic optic nerve sheath diameter (onsd) in detection of eicp. methods: sonographic onsd of patients with head trauma or cerebrovascular accident suspic...
متن کاملSonography for determining the optic nerve sheath diameter with increasing intracranial pressure in a porcine model.
OBJECTIVES This study investigated whether it is feasible to use sonography to monitor changes in the optic nerve sheath diameter in a porcine model. METHODS A fiber-optic intracranial pressure transducer was surgically placed through the frontal sinus directly into the brain parenchyma of adult Yorkshire pigs (n = 5). A second bolt was placed on the contralateral side for intraparenchymal fl...
متن کاملCorrelation of Optic Nerve Sheath Diameter with Direct Measurement of Intracranial Pressure
Background: Measurements of the optic nerve sheath diameter (ONSD) using bedside ultrasound (US) have been shown to correlate with clinical and radiologic signs and symptoms of increased intracranial pressure (ICP). Objectives: Previous literature has identified 5 mm as the ONSD measurement above which patients exhibit either clinical or radiologic signs of elevated ICP. The goals of this study...
