- W2106543176 abstract "To compare cardiac index (CI) values obtained by pulmonary artery thermodilution (CIPA), arterial thermodilution (CITD), and arterial pulse contour analysis (CIPC) during rapid fluid administration, as accurate and rapid detection of CI changes is critical during acute preload changes for guiding volume and vasopressor therapy in critically ill patients, and the accuracy of CIPC during acute changes in loading condition is currently unknown. Prospective clinical study. Cardiac surgical intensive care unit of a university hospital. Seventeen American Society of Anesthesiologists (ASA) physical status II and III patients, aged 32 to 76 years, with normal left ventricular function during the early postoperative period after elective coronary artery bypass graft surgery. After baseline determinations of CIPA, CIPC, and CITD were made, fluid loading was performed using 10 mL times body mass index of hydroxyethyl starch 6%. CIPA, CIPC, and CITD were determined, and changes in CI (ΔCI) were calculated. Fluid load was repeated until no increase in stroke volume index (ΔSVI <10%) was achieved. Regression analysis between CIPA/CIPC, CIPA/CITD, and CIPC/CITD revealed r2 = 0.92, r2 = 0.92, and r2 = 0.98. Regression analysis between ΔCIPA/ΔCIPC, ΔCIPA/ΔCITD, and ΔCIPC/ΔCITD revealed r2 = 0.57, r2 = 0.67, and r2 = 0.74, respectively. Bland-Altman analysis was used to determine accuracy and precision of the 3 methods compared. The mean differences (m) and SD between ΔCIPA/ΔCIPC, ΔCIPA/ΔCITD, and ΔCIPC/ΔCITD resulted in m = −1.01%, SD = 6.51%; m = −0.83%, SD = 5.80%; and m = −0.33%, SD = 4.65%, respectively. Compared with pulmonary artery thermodilution, arterial pulse contour analysis reflects relative changes in CI during rapid changes of preload with clinically acceptable accuracy." @default.
