目的 探讨巨大儿的病因及其相关因素,寻求正确的处理方法,降低围生期母婴并发症。方法对巨大儿70例临床资料进行分析。结果 巨大儿高发于多胎、肥胖、孕期体重增加明显的孕妇。B超对巨大儿的预测准确率达74.29％。巨大胎儿出现最多的妊娠合并症为妊娠糖尿病;产时及产后多发的并发症为产后出血,剖宫产并不能减少产后出血的发生。结论 预测为巨大儿严密观察产程,适当放宽剖宫产指征,减少母婴并发症的发生。 胎儿体重达到或超过4000g者称为巨大胎儿。近年来,随着围产医疗研究的发展,超声诊断技术的不断提高其危害已被广大产科工作者所认识。为探讨巨大儿形成的有关因素,寻求正确的处理方法,降低母婴并发症,本文分析了巨大儿70例,以供今后临床处理参考。 Objective To explore the etiology and related factors of giant children, to seek the correct treatment and reduce perinatal maternal and infant complications. Methods The clinical data of 70 cases of giant children were analyzed. The results of children with high incidence of multiple births, obesity, pregnancy weight gain significantly pregnant women. B super giant children’s prediction accuracy of 74.29%. Huge fetus occurs in pregnancy complications of gestational diabetes mellitus; multiple intrapartum and postpartum complications of postpartum hemorrhage, cesarean section and can not reduce the incidence of postpartum hemorrhage. Conclusion It is forecasted that the macrosomia closely monitor the labor process, appropriately relax indications of cesarean section and reduce the incidence of maternal and infant complications. Fetal weight of 4000g or more are called huge fetuses. In recent years, with the development of perinatal medical research, the continuous improvement of ultrasound diagnostic technology has been recognized by the majority of obstetric workers. In order to explore the related factors of macrosomia, to find the correct treatment method and reduce the complications of mother and child, 70 cases of macrosomia were analyzed in this paper for reference for future clinical treatment.
