【摘要】 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更多还原

【Abstract】 In Ovder to study the cardiac function in neonates with meconium aspiratory syndrome(AMS),cardiac function in 20 normaln ewborn and 20 neonates with MAS were tested by SSD650 Aloka Doppler Echocardio graphy.Results Showed left cardiac function EF%,A/E(53.62,0.76)and right C ardiac function COL/min,A/E(0 85,0 78)were signifcantly lower than thoses in control(62.14,1.15 and 1.10,1.22P<0 05 or 0.01),Right cardiac function COL/min,A/E(0.80,0.74)with persistent pulmonary hypertension (PPHN) were significantly lower than thoses of patients without PPHN(0.91,0.82,P<0 05),and decreases of right Cardiac function were possitive correlated with level of pulmonary artery pressure.Thesepsre the cardiac function in cases of MAS changed significantly,and right cardiac function of MAS with PPHN changed more significantly.
