探讨胎粪吸入综合征 (MAS)及并发持续肺动脉高压 (PPHN)患儿的心功能变化。应用 SSD6 5 0 - Aloka超声多普勒诊断仪检测 40例正常新生儿和 MAS患儿的心功能。结果表明 :MAS患儿左心功能 EF% (5 3.6 2 )较对照组 (6 2 .14) ,A/ E(0 .76 )较对照组 (1.15 )均低和右心功能 COL / min(0 .85 )较对照组 1.10及 ,A/ E(0 .78)较对照组 1.2 2均明显降低 ,P均 <0 .0 5或 0 .0 1。合并 PPHN患儿右心功能 COL / mim(0 .80 ) ,A/ E(0 .74)比未合并 PPHN患儿 COL / min(0 .91) ,A/ E(0 .82 )明显降低 ,P <0 .0 5 ,且右心功能受损 (CO、A/ E)与肺动脉压力增加呈明显正相关 (r =0 .84,0 .79)。因此 MAS患儿心功能有明显改变 ,并发 PPHN患儿右心功能改变更明显
To investigate the changes of cardiac function in children with meconium aspiration syndrome (MAS) and concurrent persistent pulmonary hypertension (PPHN). The cardiac function of 40 normal neonates and MAS children was detected by SSD6 50 - Aloka Doppler sonography. The results showed that left ventricular ejection fraction (EF) of children with MAS was lower than that of the control group (6.22), A / E (0.76) and control group (1.15) 0.85) than the control group 1.10 and, A / E (0.78) than the control group 1.2 2 were significantly lower, P <0.05 or 0.01. Compared with those without PPHN, COL / min (0.91) and A / E (0.82) in children with PPHN were significantly lower (P < P <0.05, and impaired right cardiac function (CO, A / E) was positively correlated with pulmonary artery pressure (r = 0.84, 0.79). Therefore, MAS children with significant changes in cardiac function, concurrent PPHN children with right heart function changes more pronounced
