Abstract EN
Objective.
Today, there exist several different pulse contour algorithms for calculation of cardiac output (CO).
The aim of the present study was to compare the accuracy of nine different pulse contour algorithms with transpulmonary thermodilution before and after cardiopulmonary bypass (CPB).
Methods.
Thirty patients scheduled for elective coronary surgery were studied before and after CPB.
A passive leg raising maneuver was also performed.
Measurements included CO obtained by transpulmonary thermodilution (COTPTD) and by nine pulse contour algorithms (COX1–9).
Calibration of pulse contour algorithms was performed by esophageal Doppler ultrasound after induction of anesthesia and 15 min after CPB.
Correlations, Bland-Altman analysis, four-quadrant, and polar analysis were also calculated.
Results.
There was only a poor correlation between COTPTD and COX1–9 during passive leg raising and in the period before and after CPB.
Percentage error exceeded the required 30% limit.
Four-quadrant and polar analysis revealed poor trending ability for most algorithms before and after CPB.
The Liljestrand-Zander algorithm revealed the best reliability.
Conclusions.
Estimation of CO by nine different pulse contour algorithms revealed poor accuracy compared with transpulmonary thermodilution.
Furthermore, the less-invasive algorithms showed an insufficient capability for trending hemodynamic changes before and after CPB.
The Liljestrand-Zander algorithm demonstrated the highest reliability.
This trial is registered with NCT02438228 (ClinicalTrials.gov).
