Abstract：Objective In order to explore the diagnostic value of color Doppler ultrasound in the prediction of newborn ar-rhythmias by intravenous catheter parameters combined with trivascular section.Methods 98 pregnant women who underwent prenatal examination were analyzed,and then were divided into 11 cases in the arrhythmia group and 87 cases in the normal rhythm group according to whether the newborns had arrhythmia after birth.Color Doppler ultrasonography was performed to mea-sure and compare the venous catheter blood flow parameters[peak ventricular systolic velocity(S),peak ventricular diastolic ve-locity(D),atrial systolic maximum flow velocity(A),mean time peak flow velocity(TAmax)]and resistance parameters[S/D,pulsatility index(PI),preload index(PLI),peak venous flow velocity index(PVIV)]and three-vessel section measurement in-ternal diameters of superior vena cava,ascending aorta and pulmonary artery between the two groups.The ROC curve was used to evaluate the predictive efficiency of intravenous catheter parameters,three-vessel sections measurement parameters and their com-bination in newborn arrhythmia.Results The fetal pulsatile index(PI),preload index(PLI)and peak velocity index vein(PVIV)in the arrhythmia group were significantly higher than those in the normal rhythm group,while the internal diameters of superior vena cava,ascending aorta and pulmonary artery in the arrhythmia group were significantly lower than those in the normal rhythm group(all P<0.05).The venous catheter parameters,the three-vessel section measurement parameters and the area under the ROC curve of the combination of the two were 0.759,0.801 and 0.852,respectively.The diagnostic efficiency of joint testing was higher than that of individual indicators(P<0.01).Conclusion The venous catheter parameters combined with three-vessel section measurement parameters can improve the specificity and coincidence rate of newborn arrhythmia predictive efficiency,which has high diagnostic value.
