摘要
本研究应用PDE测量22例单纯左向右分流型先心病患儿的Qp、Qs及Qp/Qs,与同期心导管Fick法测值进行相关回归分析,结果表明二者呈显著正相关(r=0.90～0.91.P<0.001),其中肺动脉高压组PDE所测的Qp、Qs及Qp/Qs与Fick法测值亦呈显著正相关(r=0.84～0.93,P<0.001)。研究表明,PDE是测量Qp、Qs及Qp/Qs的一种可靠方法,无刨伤性,安全准确,操作简便,可重复使用,尤其适用于小儿和危重病人。
In 22 children with congenital heart disease of simple left to right shunt, Qp. Qs and Qp/Qs were evaluated simultaneously by pulsed doppler echocardiography (PDE) and Fick's method. The results showed that there was significantly positive correlation between these two methods (r=0.90～0.91, P<0.001). PDE would be a reliable method in the evaluation of Qp, Qs and Qp/Qs. It is noninvasive, very safe, simple and can be used repeatedly. It is more suitable for children and critical patients.
