Can Vena Cava Ultrasound Guided Volume Repletion Prevent Spinal Induced Significant Hypotension in Elective Patients?
Switzerland160 participantsStarted 2014-05
Plain-language summary
Aim of this study is to determine whether Inferior Vena Cava analyzed by trans-thoracic echocardiography is an effective method to guide titrated fluid repletion in non critical patients, in order both to decrease post procedural significant hypotension rate and to avoid unnecessary fluid overload in patients undergoing spinal anesthesia for elective surgical procedures
