Sonographic optic nerve sheath diameter as a surrogate measure for intracranial pressure in anesthetized patients in the Trendelenburg position
BACKGROUND It remains to be elucidated whether the Trendelenburg position increases intracranial pressure (ICP). ICP can be evaluated by measuring the sonographic optic nerve sheath diameter (ONSD). We investigated the effect of the isolated Trendelenburg position on ONSD in patients undergoing robot-assisted laparoscopic radical prostatectomy. Additionally, we evaluated the effect of the Trend...
متن کاملChanges in intraocular pressure and optic nerve sheath diameter in patients undergoing robotic-assisted laparoscopic prostatectomy in steep 45° Trendelenburg position
BACKGROUND To evaluate changes in intraocular pressure (IOP) and intracerebral pressure (ICP) reflected by the optic nerve sheath diameter (ONSD) in patients undergoing robotic-assisted laparoscopic prostatectomy (RALP) in permanent 45° steep Trendelenburg position (STP). METHODS Fifty-one patients undergoing RALP under a standardised anaesthesia. IOP was perioperatively measured in awake pat...
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 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 کاملAccuracy of Noninvasive Intraocular Pressure or Optic Nerve Sheath Diameter Measurements for Predicting Elevated Intracranial Pressure in Cryptococcal Meningitis
BACKGROUND Cryptococcal meningitis is associated with increased intracranial pressure (ICP). Therapeutic lumbar puncture (LP) is recommended when the initial ICP is >250 mm H2O, yet the availability of manometers in Africa is limited and not always used where available. We assessed whether intraocular pressure could be a noninvasive surrogate predictor to determine when additional therapeutic L...
