The Effect of Patient Position Changes on Advanced Cardiac Indices in Cancer Surgery

Patients who underwent major abdominal cancer surgery using ODM in the operating room of our hospital between November 2021 and November 2022 were identified from the Anesthesiology Clinic records and examined according to whether they were operated with open or closed (laparoscopic) methods. Demographic data, vital signs, amount of bleeding, type and amount of fluid administered, and the results of cardiac index measurements performed with the ODM device in the supine and trendelenburg positions (45 degrees) were analyzed. Parameters recorded with the ODM device; CO: Cardiac output, FTc: Flow time corrected, PV: Peak velocity, SD: Stroke distance.
