CardioQ vs Thermodilution Measurements of Cardiac Output

Not Applicable
Completed
Conditions
Comparison of CardioQ and Thermodilution Derived Cardiac Output Measurements
Registration Number
NCT01744795
Lead Sponsor
Hasse Moller-Sorensen
Brief Summary

Minimal invasive monitoring systems of central hemodynamics are gaining increasing popularity. The present study investigates the precision of the esophageal doppler (CardioQ) derived cardiac output and its agreement with pulmonary artery catheter thermodilution (PAC TD) for measuring CO during steady state and with induced hemodynamic changes in patients scheduled for elective cardiac surgery.

Detailed Description

Twenty-five patients are planned to be enrolled. After induction of anesthesia, insertion of the PAC and the esophageal-doppler probe, the patient are placed in the following successive positions: a) supine, b) head-down tilt, c) head-up tilt, d) supine, e) supine with phenylephrine administration f) pace heart rate 80 bpm, g) pace heart rate 110 bpm, and CO are measured simultaneously using the CardioQ and PAC TD.

Primary Outcome Measures
NameTimeMethod
Agreement of cardiac output determined with CardioQ, compared with thermodilutionData are collected in the perioperative period (30min.)

Data are collected for each patient in the perioperative period. Patients are followed in the first 24 hours. Data will after inclusion of the last data be analysed and appropiate statistics aplied.
