Effect of VExUS Ultrasound Protocol (Venous Excess Ultrasound) on Perioperative Fluid Management, on the Incidence of Postoperative Pulmonary Complications and Postoperative Acute Kidney Injury in Patients Undergoing Thoracic Surgery
Trial Parameters
Brief Summary
This study aims to investigate the effect of a VExUS ultrasound guided protocol of perioperative fluid management within a goal-directed therapy framework, on postoperative respiratory complications, and the occurrence of acute kidney injury (AKI) in patients undergoing thoracic surgery.
