Abdominal Cancer, Blood Pressure, Cardiac Indices
Conditions
Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Cardiac Output | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
| Stroke Volume | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
| Flow time corrected | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
| Peak Velocity | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
| Stroke Distance | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
| Mean arterial pressure | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
| Pulse | Immediately after induction of anaesthesia and at any stable time during the case | 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. |
