摘要
目的探讨汉族和维族正常单胎胎儿颈项透明层(NT)厚度是否存在差异性及其参考值范围。方法选取2009年8月—2012年8月在我院妇产科超声门诊行NT检查且胎儿产前及产后1周均未发现异常的孕妇8161例,其中汉族5025例,维族3136例,对不同孕周维族和汉族胎儿NT值进行比较分析。采用线性回归的方法计算不同孕周胎儿NT厚度的第5%、50%、第95%位数。结果孕11~13“周汉族与维族相同孕周的孕妇年龄及胎儿NT厚度间差异均无统计学意义(P〉0.05),孕11—13“周汉族与维族胎儿的第95%位数均为0.22em。结论妊娠11—13“周,汉族和维族胎儿的NT值不存在民族差异性。就本地区而言把NT参考值设定在0.22cm可能是行之有效的。
Objective To study the differences of nuchal translucency (NT) thickness between Han nationality and Uighurs, and figure out its normal value. Methods Eight thousand one hundred and sixty - one pregnant women with health fetus taking NT examination in our department between August 2009 and August 2012 were enrolled in the study. There were 5 025 woman in Han group and 3 136 women in Uighur group. The fetal NT thickness in the two groups at different gestational weeks was measured and analyzed. And the normal ranges of fetal NT thickness were analyzed with linear regressions. Results There was no significant difference in the age of the pregnant women and the NT thickness at 11 - 13 +6 weeks between the two groups ( P 〉 0.05) . The 95th percentiles of fetal NT thickness at 11 - 13^+6 weeks in Han group and Uighur group were both 0. 22 em. Conclusion There was no ethnic difference in fetal NT thickness at 11 - 13 +6 gestational weeks. The normal value of fetal NT thickness might be 0. 22 cm in Xinjiang.
