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

Dr Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital80 enrolled

Overview

Esophageal Doppler Monitoring (Deltex CardioQ Esophageal Doppler Monitor, ODM) is used to manage patients' fluid therapy by non-invasively measuring continuous cardiac output with an esophageal probe. The aim of this study was to compare the effects of patient position changes on cardiac indices and vital signs in patients who underwent major abdominal cancer surgery with laparoscopic and open surgery using ODM.

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.

Primary Outcomes

Cardiac Output

Measurement of cardiac output with the oesophageal doppler device immediately after induction of anaesthesia and in the middle of the case in both supine and trendelenburg position of the patient to see whether there is a significant difference in positional change.
