Ultrasound-based imaging in neurocritical care patients: a review of clinical applications

Abstract

In conclusion, US imaging is an important diagnostic tool that provides real-time information at the bedside to stratify risk, monitor for complications, and guide invasive procedures in NCC patients.

Advances in Cerebral Monitoring for the Patient with Traumatic Brain Injury

“…14 Ultrasound has been repeatedly validated in neurocritical care as an imaging technique that can be used to examine both dynamic and static structures in real time. 15 …”

Aplicaciones de la ultrasonografía en el sistema nervioso central para neuroanestesia y cuidado neurocrítico

“…Las dos aplicaciones más aceptadas del doppler trascraneano son control de vasoespasmo en pacientes con hemorragia subaracnoidea (evidencia clase IIa) 16,38-47 y el apoyo del diagnóstico de muerte cerebral (evidencia IIa) [39][40][41][42][43][44][45][46][47][48] . Otras aplicaciones pero aún con evidencia limitada son el neuromonitoreo a través de velocidades de flujo en las principales arterias cerebrales, en el que se pretende monitorizar la hemodinámica cerebral [42][43][44][45] .…”

“…Otras aplicaciones pero aún con evidencia limitada son el neuromonitoreo a través de velocidades de flujo en las principales arterias cerebrales, en el que se pretende monitorizar la hemodinámica cerebral [42][43][44][45] . Se ha propuesto la evaluación de la integridad de la autorregulación cerebral a través de la relación del flujo de la arteria cerebral media y sus velocidades medidas por doppler con la presión arterial media 46 .…”

Ultrasound applications in the central nervous system for neuroanaesthesia and neurocritical care

“…The two most widely accepted applications for transcranial Doppler ultrasound are vasospasm control in patients with subarachnoid haemorrhage (Class IIa evidence), 16,[38][39][40][41][42][43][44][45][46][47] and brain death confirmation (Class IIa evidence). [39][40][41][42][43][44][45][46][47][48] Other applications, although with limited evidence, include the use of flow velocities in the main cerebral arteries as a means to monitor brain haemodynamics.…”

“…[39][40][41][42][43][44][45][46][47][48] Other applications, although with limited evidence, include the use of flow velocities in the main cerebral arteries as a means to monitor brain haemodynamics. [42][43][44][45] The use of the relationship between the middle cerebral artery flow and velocities as measured by Doppler and the mean arterial pressure has been proposed for assessing the integrity of cerebral autoregulation. 46 Of interest in neurocritical care and neuroanaesthesia has been the possibility of having a way to monitor critically ill patients in the intensive care room or in the operating room.…”
