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

TL;DRAbstract

Ultrasonography performed by non-radiologist specialists is a tool that contributes to the diagnosis and monitoring of neurocritical patients. It is a non-invasive, low-cost, accurate and fast method that helps improve safety and timeliness in settings where prompt decision-making is imperative, such as in the operating room, critical care units or the emergency room. The objective is to conduct a narrative review, presenting ultrasound applications focused on the central nervous system that may be useful in neuroanaesthesia and neurocritical care. A search was performed of related terms on databases in the medical literature. Relevant papers where selected and reviewed to perform a non-systematic review focusing on the visualization of the midline and lateral ventricles, the measurement of the optic nerve sheath as a surrogate marker of intracranial hypertension, and the use of colour Doppler for visualizing the middle cerebral artery. It is expected that the use of ultrasound examina
