目的：研究早期诊断妊娠糖尿病（ＧＤＭ）控制血糖，以减少母婴并发症。方法：观察和分析妊娠糖尿病２２例及健康孕妇３０例的妊娠结局。结果：ＧＤＭ组中病理妊娠的发生率占５４５４％，手术产率占７２７２％，胎婴儿疾病的发生率为６８１７％；对照组病理妊娠的发生率占２２７２％，手术产率占３１７２％，胎婴儿疾病的发生率为１８１８％。ＧＤＭ组母婴合并症的发生率明显高于正常孕妇，并与血糖水平密切相关。结论：早期诊断ＧＤＭ及控制血糖是减少妇婴并发症的关键。 Objective: To study the early diagnosis of gestational diabetes mellitus (GDM) control of blood glucose, in order to reduce maternal and child complications. Methods: The pregnancy outcome was observed and analyzed in 22 cases of gestational diabetes mellitus and 30 healthy pregnant women. Results: The incidence of pathological pregnancy in GDM group was 5454%, the operation yield was 7272%, the incidence of fetal infant disease was 6817%. The incidence of pathological pregnancy in control group was 2272% Surgical yield accounted for 31  72%, the incidence of fetal infant disease was 18  18%. The incidence of maternal complications in GDM group was significantly higher than that in normal pregnant women, and was closely related to blood glucose level. Conclusion: Early diagnosis of GDM and blood sugar control is the key to reduce the complications of maternal and infant.
