Patients admitted to the neurocritical care unit (NCCU) are at risk for secondary brain injury
that frequently can exacerbate outcome. Consequently, current NCCU management …

Introduction The purpose of this study was to determine if noninvasive transcranial oxygen
saturation (StcO 2) and Bispectral Index (BIS) correlate with severe traumatic brain injury …

Objectives: Cerebral vasospasm in the first 2 weeks after aneurysmal subarachnoid
hemorrhage is recognized as a major predictor of delayed cerebral ischemia. The routine …

Inadequate cerebral blood flow (CBF) after head injury is an important cause of secondary
ischaemic damage. Rapid identification of episodes of hypo-or hyperperfusion would allow …

Several non-invasive and invasive modalities have been used to monitor patients for
cerebral ischemia after subarachnoid hemorrhage. A literature search was performed to …

Traumatic brain injury (TBI) is associated with the severest casualties from Operation Iraqi
Freedom (OIF) and Operation Enduring Freedom (OEF). From October 1, 2008, the US Army …

Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure
cerebral blood flow velocity (CBF‐V) in the major intracranial arteries. It involves use of low …

Acute cerebrovascular congestion after a closed head injury is significantly related to
intracranial hypertension. As an indirect method of cerebral blood flow measurement …

Measurement of blood flow velocity in the basal intracranial arteries using transcranial
Doppler ultrasonography can provide useful information in neurosurgical intensive care …

Transcranial Doppler (TCD) ultrasonography is an inexpensive, noninvasive means of
measuring blood flow within the arteries of the brain. In this review, the authors outline the …
