Assessment Of Carotid Flow During General Anesthesia

Medical University of Warsaw61 enrolled

Overview

Proper identification of patients who would benefit from fluid infusion (fluid responsiveness) is one of the most crucial challenges in anaesthesia and critical care. Reliability of several invasive measurements used for this purpose for many years have been questioned recently. The study will evaluate consistency between carotid artery flow derivatives and standard haemodynamic measurement (LIDCO rapid) in navigation of intraoperative fluid therapy.
