The effect of insulin therapy at different periods on pregnancy outcome of gestational diabetes patients

Abstract

Objective To discuss the maternal and neonatal outcomes in gestational diabetes patients given insulin therapy at different periods.Methods Clinical data of 52 cases of gestational diabetes patients admitted from May 2011 to June 2013 in The Central Hospital of Ningbo Development Zone were analyzed,among whom 28 cases accepted insulin therapy before 32 weeks of pregnancy(early diagnosis treatment group)and the rest 24 cases accepted insulin therapy after 32 weeks of pregnancy(late diagnosis treatment group).The pregnancy outcome,hemodynamic parameters,incidence of hypertension,and the outcome of neonates were compared.Results The blood glucose of the 52 patients was controlled in the normal range after insulin therapy.However,incidence of preterm and cesarean section was significantly higher in the early diagnosis treatment group than that in the late diagnosis treatment group (P ＜ 0.05).The incidence of neonatal ketosis,fetal distress,and the incidence of macrosomia was significantly lower in the early treatment group than that in late diagnosis treatment group (P ＜ 0.05).The incidence of pregnancy-induced hypertension had not statistical difference between the two groups of pregnant women(P ＞ 0.05).S/D value of the two groups of pregnant women had no statistical significance(P ＞ 0.05).RI and PI value was significantly higher in the late diagnosis treatment group than those in early diagnosis treatment group(P ＜0.05).Conclusions The blood glucose of patients was controlled in the normal range after insulin therapy.Insulin therapy before 32 weeks of pregnancy can improve pregnancy outcomes.However,further research is needed for specific treatment programs.
