[摘要] 目的应用二维超声观察不同孕周正常胎儿胸腹纵径比、总肺面积及肺纵径的参数值,探讨
胎儿胸腹纵径比等参数对评估肺发育的应用价值。方法对592例正常单胎妊娠18~40周胎儿进行肺
二维超声扫查,采用标准四腔心观及胎儿躯干冠状切面,分别测定心脏面积、胸廓面积,肺尖至相应膈肌穹
窿顶部的直线距离与膈肌穹窿顶部至胎儿膀胱底部的距离之比(胸腹纵径比),应用相关回归分析拟合总
肺面积及肺纵径随孕周增长的回归方程。结果正常妊娠胎儿总肺面积及肺纵径随着孕龄的增加而增
大, 总肺面积、肺纵径随着孕周增长的最适回归方程分别为:总肺:y +,R2= =;肺纵
径:y=X+,R2=0. 892。不同孕周胎儿胸腹纵径比在恒定范围内(~)。结论
18~40周胎儿胸腹纵径比在恒定范围内,总肺面积与肺纵径值随孕周增长,上述参数可为产前评估胎肺发
育提供有价值的参考指标。
