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

Abstract

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 neuroanesthesia 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 examination of the central nervous system will continue to evolve given its advantages, good correlation with studies considered as the gold standard, and the growing availability of the device. Advancements in this field are expected to improve timeliness and provide objective guidance for decision-making. We recognize the importance of developing skills in the use of this method of exploration in those services where it is required.
