在正常碘营养状况下,新生儿 TSH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向高值偏移的重要因素之一

In the first time,the results suggest that after iodine-nutritional status in pregnant women is improved,elevation of neonatal 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.It is suggested that umbilical cord blood TSH values from vaginal birth should be corrected by those from cesarean section or heel blood

首次揭示在孕妇碘营养明显改善后,新生儿在娩出过程中TSH的升高是一种普遍现象,以阴道娩出者最明显,是导致脐带血TSH向高值偏移的重要因素之一,并建议用剖宫产脐带血TSH值或足跟血TSH值校正阴道产脐带血TSH值。
