目的:应用超声测量各孕周胎儿鼻前皮肤层厚度(PT)及鼻骨长度(NB),探讨其增长规律,统计各孕周胎儿PT及NB的正常值范围。方法:2012年1月~12月在我院行产前超声检查的孕妇2158例,观察和记录胎儿鼻骨发育情况,测量PT及NB值,分析二者的关系,并分别分析与孕周的关系。结果:PT与NB值随孕周增加呈增长趋势。PT与孕周的相关系数为0.769(P<0.01),NB与孕周的相关系数为0.748(P<0.01),PT与NB的相关系数为0.694(P<0.01)。结论:胎儿PT及NB均随孕周增加而增加,并均与孕周呈直线相关;PT与NB呈直线相关。
Objective:The ultrasonic measurement of fetal prenasal thickness(PT)and nasal bone length (NB), to investigate the growth law, the range of normal value of each gestational week’s PT and NB. Methods:From 2012 January to December in our hospital, 2158 cases of prenatal ultrasound examination of pregnant women,observe and recorde the fetal nasal bone’s development, measure PT and NB, analysis the relationship between the two, and then analyze relationship with gestational week. Results:PT and NB values increased with the increase of the gestational week. The correlation coefficient of PT and gestational week is 0.769(P<0.01), the correlation coefficient of NB and gestational week is 0.748(P<0.01), the correlation coefficient of PT and NB is 0.694(P<0.01). Conclusions:Fetal PT and NB increased with gestational week, and with the gestational weeks was linearly related;PT and NB is linear correlation.
