目的通过对１５９例巨大胎儿的临床分析，寻找准确诊断巨大儿的相关因素。方法将１５９例巨大儿（出生体重≥４０００ｇ）纳入研究，选择相应时间（２日内）分娩的１５９例出生体重＜４０００ｇ的正常足月儿作为对照；比较孕妇年龄、身高、体重、孕周、孕产次、分娩方式、合并症及新生儿有关情况。结果巨大儿组母亲身高、孕期体重增长、分娩孕周、孕产次均高于对照组，并有统计学差异。巨大儿男婴多于女婴。巨大儿组分娩方式以剖宫产为主，剖宫产率为７１０％，高于对照组（３２７％）。结论产妇体重、身高、分娩孕周及宫高、腹围是产前诊断巨大儿的相关因素。超声检查对估计巨大胎儿有参考价值。巨大儿的分娩方式以剖宫产为相对安全。
Objective To analyze the related factors of macrosomia by the clinical analysis of 159 huge fetuses. Methods A total of 159 hypertensive children (birth weight≥4000g) were enrolled in the study. 159 normal full-term infants born at the birth weight of <4000g at the corresponding time (within 2 days) were selected as controls. The age, height, weight, gestational age, Delivery times, mode of delivery, complications and newborns. The results of the giant group of maternal height, weight gain during pregnancy, birth gestational age, pregnancy and childbirth were higher than the control group, and there was a significant difference. Huge children have more baby boys than boys. The delivery method of giant children was mainly cesarean section, cesarean section rate was 710%, higher than the control group (327%). Conclusion Maternal body weight, height, gestational age at childbirth and uterine height and abdominal circumference are the related factors in prenatal diagnosis of macrosomia. Ultrasound to estimate the huge fetus have reference value. Giant child’s delivery method to cesarean section is relatively safe.
