ABSTRACT
Objective To investigate the value of measurement of cardiac output in children by bio-reactance versus echocardiography.Methods Pediatric patients admitted in pediatric department of Peking University First Hospital from September to December 2012 who needed hemodynamic monitoring were enrolled prospectively.Cardiac index(CI)and stroke volume(SV)were measured by echocardiography and non-invasive cardiac output measurement(NICOM)and compared by Spearman correlation and Bland-Alt-man analysis.Results Thirty patients were included.The median age was 7.25 years.CI[M(P5 ,P95 )] measured by NICOM and echocardiography were correlated significantly[3.42(2.28,4.92)L /(min?m2 ) vs.3.51 (2.94,4.85 )L/(min?m2 ),R =0.385,P =0.035 ].Bland-Altman analysis revealed a bias of-0.22 L/(min?m2 )(P =0.051 ),limits of agreement of -1.40 to 0.95 L/(min?m2 ).SV[M(P5 ,P95 )] measured by NICOM and echocardiography were correlated more significantly [36.3 (12.6,87.8 )ml vs.39.4(14.7,86.9)ml,R =0.768,P ﹤0.001 ].Bland-Altman analysis revealed a bias of -3.1 ml(P =0.176),limits of agreement of -27.4 to 21.2 ml.Conclusion There is no significant difference between NICOM and echocardiography for the measurement of CI and SV in pediatric patients.Further validation studies need to be conducted before routine clinical use.
