Evaluation of predicting the ductus arteriosus closure in preterm infants by echocardiography
摘要
Abstract
Objective To investigate the values of echocardiographic parameters for predicting the spontaneous closure of the ductus arteriosus in preterm infants .Methods A retrospective study of 110 preterm infants from October 2013 to October 2014 in our hospital was done .Examination was done at 1 ,3 ,7 d with echocardiography for those infants .Diameter of left atrium(LA) ,aotic root(AO) and arterial canal‐related parameters (the smallest width of ductal color Doppler flow jet and the maximum velocity at the ductus) at first .Preterm infants in this study were divided into two groups .The early patent ductus arterisus group included ones whoes ductus didn′t closed spontaneous in 7 d ,and the control group included ones whoes ductus closed spontaneous in 7 d ,and then the echocardiographic parameters between the two groups were compared .Results (1)The rates of ductus arteriosus sponta‐neous closure in preterm infants at 3 ,7 d were 70 .9% (78/110) ,78 .2% (86/110) ,respectivly .(2)When compared with the control group ,The rate of LA/AO in patent ductus arterisus group were higher than that of the control group(P<0 .01);The smallest width of ductal color Doppler flow jet in patent ductus arterisus group were bigger than that of the control group(P<0 .01);The maximum velocity at the ductus in patent ductus arterisus group were lower than that of the control group(P<0 .05) .(3)The best critical points of the LA/AO ,the smallest width of ductal color Doppler flow jet and the maximum velocity at the ductus of the spontaneous ductus arteriosus closure in preterm infants were 1 .32 mm ,2 .56 mm and 185 .5 cm/s ,respectivly .Conclusion Echo‐cardiography plays a significant role in prediction of the spontaneous closure of the ductus arteriosus in preterm infants .关键词
