BackgroundSpinal anaesthesia is commonly used for many surgical procedures. One of its potential complications is arterial hypotension, which is nowadays prevented by an empirical fluid administration without any hemodynamic status assessment. However, this practice could increase the risk of volume overload in cardiovascular high-risk patients. Two non-invasive tests are performed to identify fluid-responsiveness: the Inferior Vena Cava Ultrasound (IVCUS) and the Passive Leg Raising Test (PLRT)...
