Assessment of intracranial pressure with ultrasonographic retrobulbar optic nerve sheath diameter measurement
BACKGROUND Ultrasonograpic retrobulbar optic nerve sheath diameter (ONSD) measurement is considered to be an alternative noninvasive method to estimate intracranial pressure,but the further validation is urgently needed. The aim of the current study was to investigate the association of the ultrasonographic ONSD and intracranial pressure (ICP) in patients. METHODS One hundred and ten patients...
متن کاملPerioperative 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 کاملOptic Nerve Sheath Diameter as a Bedside Assessment for Elevated Intracranial Pressure
A previously fit and healthy 26-year-old lady with no significant medical history presented with a two-month history of headaches. The headaches were prolonged, generalised, and unusually severe for the patient. Examination revealed papilloedema. The patient's optic nerve sheath diameter was measured 3 mm posterior to the globe and found to be 7.5 mm. The patient subsequently had computed tomog...
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 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...
