本文对高原地区正常孕妇自21至41孕周测量了子宫底高度共2651人次,并用统计学方法计算出第10、50,90百分位数绘制成曲线,做为高原地区胎儿宫内生长的正常值参考,低于第10分位数可诊断胎儿宫内生长迟缓。本文正常值与平原地区上海正常值比较的结果:各孕周第10、50、90百分位数均明显低于上海值,各孕周宫高低于上海平均1、74厘米(P<0.05),差别有显著性意义。表明高原地区,缺氧等因素对胎儿宫内生长发育有一定的影响。
In this paper, normal pregnant women in the plateau from 21 to 41 gestational weeks measured a total of 2651 uterine heights, and calculated by statistical methods 10,50,90 percentile drawn into a curve, as the plateau fetal growth Normal reference, below the tenth quintile to diagnose fetal growth retardation. The normal value of this article compared with the normal value of Shanghai Plain: the 10th, 50th and 90th percentiles of each gestational week were significantly lower than those of Shanghai, and the average gestational weeks were 1,74 centimeters (P <0.05) , The difference is significant. That high altitude, hypoxia and other factors on fetal growth and development have a certain impact.
