About

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.

Full 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.

Enrollment: 80 patients

Sex: All

Ages: 18 to 99 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Elective operation
• ASA 1-4

Exclusion criteria

• Heart failure
• Valvular heart disease,
• Patients with symptomatic rhythm disturbances
• ODM placement contraindicated (coagulopathy, oesophageal varices, known aortic aneurysm)

Trial design

80 participants in 2 patient groups

ODM measurements of patients undergoing open surgery in supine and trendelenburg position

Description:

After intubation, serial ODM measurements were performed in the supine and trendelenburg position of the patient and CO: Cardiac output, FTc: Flow time corrected, PV: Peak velocity, SD: Stroke distance values were recorded.

Treatment:

Procedure: cardiac indices in supine and trendelenburg position

ODM measurements of patients undergoing laparoscopic surgery in supine and trendelenburg position

Description:

After intubation, serial ODM measurements were performed in the supine and trendelenburg position of the patient and CO: Cardiac output, FTc: Flow time corrected, PV: Peak velocity, SD: Stroke distance values were recorded.

Treatment:

Procedure: cardiac indices in supine and trendelenburg position
