目的 探讨产前诊断巨大胎儿的相关因素 ,减少并发症的发生。方法 对 82 6例巨大胎儿和同期分娩的81 6例出生体重 <40 0 0 g的正常足月儿比较孕妇年龄、孕周、孕产次、分娩方式、合并症及新生儿等情况。结果 巨大胎儿组母亲的分娩孕周、孕产次均高于对照组 ,并有统计学差异。巨大儿中男婴多于女婴 ,巨大儿组的剖宫产率为 40 .2 % ,高于对照组 2 3.6 % .观察组孕 40周后分娩的巨大胎儿为 6 2 .4% ,而对照组为 31 .1 % .观察组新生儿病率高于对照组。结论 产妇的分娩孕周、产次及宫高、腹围等为产前诊断巨大胎儿的相关因素。超声检查对估计巨大胎儿有参考价值。巨大胎儿的分娩方式以剖宫产为相对安全
Objective To investigate the related factors of prenatal diagnosis of huge fetus and reduce the incidence of complications. Methods The age, gestational age, parity, mode of delivery, complications and newborns of 82 6 pregnant women with large fetuses and 81 6 pregnant women with normal birth weight <40 000 g who were born at the same period were compared. Results The mothers ’gestational age and their mothers’ birth time in the huge fetus group were higher than those in the control group, and there was statistical difference. The number of male fetuses in the huge children was higher than that of the female ones, while the rate of cesarean section in the giant children was 40.2%, which was 3.6% higher than that in the control group. The control group was 31.1% .The neonatal morbidity in the observation group was higher than that in the control group. Conclusion Maternal gestational age, parity and uterine height, abdominal circumference and other factors for prenatal diagnosis of fetal macrosomia. Ultrasound to estimate the huge fetus have reference value. The delivery of a huge fetus to cesarean section is relatively safe
