How to use cerebral ultrasound in the ICU

Description

Cerebral ultrasound is a developing point of care tool for intensivists and emergency physicians, with an important role in the diagnosis of acute intracranial pathology, such as the assessment of cerebrovascular diseases and in the noninvasive intracranial pressure measurement both in the acute clinical settings and in intensive care unit (ICU). The traditional application of transcranial doppler (TCD) by assessing blood flow velocities in the main cerebral arteries, allows the evaluation and follow up of cerebral vasospasm, cerebral perfusion pressure, cerebral autoregulation and intracranial hypertension. The use of TCD, traditionally limited to the neurosonology laboratories settings, has expanded over the last years following the introduction of B-mode ultrasound and color Doppler, the transcranial color-coded duplex ultrasonography (TCCS), opening a new window to the assessment of cerebral anatomy not only in the neurocritical patients, but also in general ICU and emergency room patients. Here we report a brief review with the intent to up-to-date and describe the main applications and use of TCD/TCCS in the setting of Neurointensive Care.
