Abstract
Bedside point of care ultrasound has acquired an extremely significant role in diagnosis
and management of neurocritical care, just as it has in other specialties. Easy availability
and increasing expertise have allowed the intensivists to use it in a wide array of
situations, such as confirming clinical findings as well as for interventional and
prognostic purposes. At present, the clinical applications of ultrasonography (USG)
in a neurosurgical patient include estimation of elevated intracranial pressure (ICP),
assessment of cerebral blood flow (CBF) and velocities, diagnosis of intracranial
mass lesion and midline shifts, and examination of pupils, apart from the systemic
applications. Transcranial sonography has also found use in the diagnosis of the cerebral
circulatory arrest. An increasing number of clinicians are now relying on the use
of ultrasound in the neurointensive care unit for neurological as well as non-neurological
indications. These uses include the diagnosis of shock, respiratory failure, deep
vein thrombosis and performing bedside procedures.
