Monitoring Blood Flow Changes Using Ultrasound During Elective Lumbar Spine Surgery Under General Anesthesia

What this Trial Is About

Researchers are evaluating perioperative hemodynamic changes in patients undergoing lumbar stabilization surgery under general anesthesia. The study focuses on using the inferior vena cava IVC collapsibility index as a possible non-invasive measure of intravascular volume status and hemodynamic changes during surgery. This observational study includes adult patients classified as ASA physical status I, II, or III who are scheduled for elective lumbar spine stabilization surgery. The study involves measuring the IVC diameter and collapsibility index using ultrasonography at specific perioperative time points before surgery, after anesthesia induction, and before extubation. Alongside ultrasound measurements, hemodynamic parameters such as blood pressure and heart rate will be recorded during these periods. The goal is to analyze changes in intravascular volume and hemodynamics throughout the surgery. Participants will undergo ultrasound imaging and continuous monitoring of vital signs during the perioperative period. The primary outcome is the IVC collapsibility index measured at three perioperative stages. Secondary outcomes include the incidence of intraoperative hypotension. The study will collect and analyze this data to assess the potential of IVC measurements as indicators of hemodynamic status during lumbar spine surgery.
