摘要
目的 探讨正常碘营养状况下新生儿促甲状腺激素 (TSH)脐带血切值及其有关影响因素。方法 在判定人群碘营养状况正常后 ,对该地区孕产妇分别检测自家盐碘、尿碘和新生儿 TSH(脐血 )值。结果 孕产妇自家盐碘中位数 40 m g/ kg,尿碘中位数 30 0 μg/ L,新生儿 TSH(脐血 )中位数 3.49m U/ L,第 95 %分位值为 12 .95m U/ L,其中正常阴道产和剖腹产 TSH(脐血 )中位数分别为 3.6 5和 2 .6 8m U/ L,差异有显著意义 (P <0 .0 5 )。结论 在正常碘营养状况下 ,新生儿 TSH(脐血 )正常值范围 0～ 12 .95 m U/ L,新生儿在分娩进程中 TSH的升高是一普遍现象 ,尤其以阴道产者明显 ,是导致 TSH(脐血 )
Objective Understand the normal on iodine nutritional condition of neonatal TSH cut-off point the cord blood.Methods The urinary iodine of prepartal women and neonatal TSH of cord blood were determined.Results The median of iodized salt and urinary iodine is 40 mg/kg and 300 μg/L.The median of neonatal TSH was 3.49 mU/L,P95%=12.95 mU/L.Conclusions The results show that after iodine nutritional status in pregnant women is improved, elevation of neonates TSH during expulsive process is a general phenomenon,especially in vaginal expulsive neonates ,vaginal birth way is one of the important factors which makes umbilical cord blood TSH tend to higher value.
