ABSTRACT
Objective To evaluate the clinical efficacy of thyroxine replacement therapy in the treatment of pregnancy patients with subclinical hypothyroidism.Methods 80 cases of patients with subclinical hypothyroidism who were admitted to our hospital from May 2011 to May 2016 were selected, they were divided into thyroxine replacement therapy treatment group ( replacement treatment group ) and conventional treatment group two groups according to the treatment methods, 40 cases in each group.The serum TSH, FT4, TG, CHO levels, childbirth, pregnancy outcomes and complications, neonatal status of the two groups were statistically analyzed.Results The serum TSH, TG, CHO levels of the replacement treatment group were significantly lower, the FT4 level was significantly higher, the difference was statistically significant (P<0.05), the trans vaginal yield rate 70.0%(28/40) was significantly higher than the conventional treatment group 35.0%(14/40), the cesarean section rate 30.0%(12/40) was significantly lower than the conventional treatment group 65.0%( 26/40 ) , the difference was statistically significant ( P<0.05 ) , the incidences of preterm delivery, postpartum hemorrhage, preeclampsia, hypoproteinemia, fetal development restriction 2.5%(1/40), 2.5%(1/40), 5.0%(2/40), 7.5%(2/40), 0 were significantly lower than the conventional treatment group 17.5%(7/40), 15.0%(6/40), 20.0%(8/40), 17.5%(7/40), 15.0%(6/40), the difference was statistically significant (P<0.05), the neonates body weight was significantly higher than the conventional treatment group, the difference was statistically significant (P<0.05), the proportions of low birth weight infants, giant infants, premature infants, asphyxia, death 0, 2.5%(1/40), 5.0%(2/40), 7.5%(2/40), 0 were significantly lower than the conventional treatment group 15.0%(6/40), 20%(8/40), 22.5%(9/40), 27.5%(11/25), 20.0%(8/40), the difference was statistically significant (P<0.05).Conclusion The clinical efficacy of thyroxine replacement therapy in the treatment of pregnancy patients with subclinical hypothyroidism is more significant than conventional treatment .
