107例患儿经1～8次检查后血清TSH值均>20 mIU/L,血FT4、TT4值在正常低值范围,治疗4周后复查,血TSH明显下降,血FT4、TT4值较前升高(均P<0.01).甲状腺B超检查7例(6.54%)显示甲状腺发育不良,7例(6.54%)甲状腺肿大血流丰富,93例(86.91%)位置大小形态无异常.左旋甲状腺素初始剂量以3～4 μg·kg-1·d-1为宜.

The serum TSH levels of 107 infants with subclinical hypothyroidism (SH) were > 20 mIU/L after 1-8 check-up, along with FT4, TT4, within low normal range. After given small dosage L-T4, for 4 weeks, blood TSH level obviously descended while FT4, TT4, ascended (all P <0.01). Seven cases of thyroid hypogenesis and 7 strumas were found by ultrasonography. It seems appropriate to use dosage of 3-4 μg·kg·-1·d-1 L-T4 in treating SH.
