摘要:
目的 探讨应用二维超声测量胎儿肺及胸腔的相关参数评价胎儿肺部发育的价值。
方法 选择行产前超声检查、孕20~40周孕妇356例,在四腔心切面上测量左右肺的横径及前后径并描记左右肺面积、心脏面积、胸廓面积及胸围,计算心脏面积/总肺面积;在左右肺最大矢状面测量左右肺纵径,计算左、右肺体积及总肺体积。应用Bivariate相关分析法分析左右肺纵径、总肺面积、总肺体积、心脏面积、胸廓面积、胸围及心脏面积/总肺面积与孕周的相关性;绘制孕20~40周胎儿左右肺纵径、总肺面积、总肺体积、心脏面积、胸廓面积及胸围的生长曲线图。
结果 获得孕20~40周胎儿左右肺纵径、总肺面积、总肺体积、心脏面积、胸廓面积及胸围的参考值范围。左右肺纵径、总肺面积、总肺体积、心脏面积、胸廓面积、胸围与孕周存在线性关系,线性回归方程:左肺纵径Y=0.120 5X+0.188 1,r=0.829;右肺纵径Y=0.193 9X-0.278 2,r=0.893;总肺面积Y=0.814 9X-10.021 0,r=0.824;总肺体积Y=4.068 2X-72.848 0,r=0.910;心脏面积Y=0.713 2X-11.229 0,r=0.915;胸廓面积Y=1.563 9X-21.852 0,r=0.916;胸围Y=0.728 6X-0.652 0,r=0.905。不同孕周胎儿心脏面积/总肺面积在稳定范围内(0.56~0.77)。各参数值随孕周增加而增长;肺面积及心脏面积在20~29周增长速度较快,胸廓面积在29周后增长速度较快,左右肺纵径及总肺体积在整个孕周基本呈匀速增长。
结论 应用二维超声可精确测量胎儿肺及胸腔的相关参数,对评估胎儿肺部发育有较高的应用价值。
Abstract:
Objective  To explore the value of two-dimensional ultrasonic measurement of fetal lung and thorax in evaluation of fetal lung development.
Methods  A total of 356 women who were between 20 and 40 weeks pregnant and underwent prenatal ultrasound scans were enrolled as subjects. In the four-chamber view, the left-right and anterior-posterior diameters of the left and right lungs were measured; areas of the left and right lungs, the heart, and the thorax, as well as chest circumference, were traced; the heart/lung area ratio was calculated. In the largest sagittal planes of the left and right lungs, the superior-inferior diameters of the left and right lungs were measured and volume of the left, right, and both lungs were calculated. Bivariate correlation analysis was used to evaluate the correlation of gestational age with the superior-inferior diameters of the left and right lungs, total lung area and volume, heart area, thoracic area, chest circumference, and the heart/lung area ratio. The growth curves of the superior-inferior diameters of the left and right lungs, total lung area and volume, heart area, thoracic area, and chest circumference were plotted for the fetuses between 20 and 40 weeks of gestation.
Results  The reference ranges of the superior-inferior diameters of the left and right lungs, total lung area and volume, heart area, thoracic area, and chest circumference were obtained for the fetuses between 20 and 40 weeks of gestation. There were linear relationships of gestational age with the superior-inferior diameters of the left and right lungs, total lung area and volume, heart area, thoracic area, and chest circumference, defined by linear regression equations of Y=0.120 5X+0.188 1 (r=0.829), Y=0.193 9X-0.278 2 (r=0.893), Y=0.814 9X-10.021 0(r=0.824), Y=4.068 2X-72.848 0 (r=0.910), Y=0.713 2X-11.229 0 (r=0.915), Y=1.563 9X-21.852 0 (r=0.916), and Y=0.728 6 X-0.652 0 (r=0.905), respectively. The heart/lung area ratio was always in the range of 0.56-0.77 for the fetuses with different gestational ages. The value of each parameter increased with increasing gestational age; the areas of the lungs and the heart grew relatively fast in 20-29 weeks, while the area of the thorax grew relatively fast after 29 weeks; the superior-inferior diameters of the left and right lungs and total lung volume increased at constant rates during the whole pregnancy.
Conclusion Two-dimensional ultrasonography provides accurate measurements of fetal lung and thoracic parameters, which holds promise for evaluation of the development of fetal lung.
