Summary
Brief summary (as posted)
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.
