【摘要】：目的监测正常妊娠中晚孕胎肺生长规律。方法599例18~40周正常单胎,按每两周分组,测量右肺在矢状面、横断面径线,描绘生长曲线。计算不同孕龄右肺面积(RLa)与头围(Hc)、胸围(Tc)及胸腔面积(Ta)的比值。应用统计分析得出相关系数。结果 RLa/Hc及RLa/Tc与孕龄的增长呈直线关系,回归方程为:(RLa/Hc:ˇY=0.948X-1.221,r2=0.898,RLa/Tc:ˇY=0.944X-1.800,r2=0.894),不同孕龄胎儿RLa/Ta在恒定范围内(0.42~0.55)。胎肺在矢状面及横断面上的径线随孕龄增加,且生长速度前后径(横断面)上下径(矢状面)左右径(横断面)。结论产前超声能评价正常胎肺的生长规律,为胎肺成熟的评估提供依据。
[Abstract]:Objective to monitor the lung growth pattern of normal middle and late pregnancy fetus. Methods 599 cases of 1840 weeks normal single fetus were divided into groups every two weeks and the right lung was measured on sagittal plane and cross section. The right lung area (RLA) and head circumference (HCC) were calculated at different gestational ages. The ratio of chest circumference (Tc) and chest area (TAA). The correlation coefficient was obtained by statistical analysis. Results RLa/Hc and RLa/Tc showed a linear relationship with the increase of gestational age. The regression equation is as follows: RLA / Hc: Yan 0.948X-1.221kr2n 0.898N RLa-r / Tc: YYN 0.944X-1.800. The diameter of fetal lung on sagittal plane and cross section increased with gestational age. The anteroposterior and anterior-posterior diameter (transverse section) of growth rate (sagittal plane) left and right diameters (sagittal plane). Conclusion Prenatal ultrasound can evaluate the growth of normal fetal lung and provide basis for the evaluation of fetal lung maturation.
