Introduction The dural sheath surrounding the optic nerve communicates with the
subarachnoid space, and distends when intracranial pressure is elevated. Magnetic …

Introduction The orbital subarachnoid space surrounding the optic nerve is continuous with
the circulation system for cerebrospinal fluid (CSF) and can be visualized by using magnetic …

Introduction The aim of this study was to evaluate the prognostic value of optic nerve sheath
diameter (ONSD) measured on the initial brain computed tomography (CT) scan for …

Introduction The optic nerve sheath diameter (ONSD) may be increased in brain-injured
patients, especially children, with intracranial hypertension. We investigated whether …

Background Although placement of an intra-cerebral catheter remains the gold standard
method for measuring intracranial pressure (ICP), several non-invasive techniques can …

Introduction The objective of this study was to determine the ability of various parameters
commonly used for the diagnosis of acute meningitis to differentiate between bacterial and …

Background Alternative noninvasive methods capable of excluding intracranial hypertension
through use of transcranial Doppler (ICP tcd) in situations where invasive methods cannot …

Introduction Non-neurological complications in patients with severe traumatic brain injury
(TBI) are frequent, worsening the prognosis, but the pathophysiology of systemic …

Introduction Correct bedside measurement of intra-abdominal pressure (IAP) is important.
The bladder method is considered as the gold standard for indirect IAP measurement, but …

Introduction The pathophysiology of sepsis-associated delirium is not completely
