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

Background Untimely diagnosis of intracranial hypertension may lead to delays in therapy
and worsening of outcome. Transcranial Doppler (TCD) detects variations in cerebral blood …

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

Background No definitive evidence exists on how intracranial hypertension should be
treated in patients with traumatic brain injury (TBI). It is therefore likely that centers and …

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

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

Background Elevated intracranial pressure (ICP) is frequent after traumatic brain injury (TBI)
and may cause abnormal pupillary reactivity, which in turn is associated with a worse …

Introduction Critically ill patients and patients undergoing high-risk and major surgery, are
instrumented with intra-arterial catheters and invasive blood pressure is considered the …

Introduction Blood pressure measurements frequently guide management in critical care.
Direct readings, commonly from a major artery, are considered to be the gold standard …
