对1996－01－01～1997－12－31两年间分娩的63例巨大胎儿（体重≥4000g）进行分析。结果发现巨大胎儿的发生率与孕期过度营养、活动量少有关．资料显示，巨大胎儿分娩期母婴并发症，如头盆不称、肩难产、新生儿窒息、产后出血均较同期正常体重儿高。因此，如何预防巨大胎儿的发生及提高巨大胎儿的产前诊断，减少分娩期并发症，提高围产质量是产科工作的重点。 Sixty-three huge fetuses (weighing ≥ 4000 g) who were delivered between January 1996 and January 1997 to December 1997 were analyzed. The results showed that the incidence of huge fetus and pregnancy over-nutrition, less activity related. Data show that the huge fetus during childbirth maternal and child complications, such as cephalopelvic disproportion, shoulder dystocia, neonatal asphyxia, postpartum hemorrhage were higher than the normal weight of children over the same period. Therefore, how to prevent the occurrence of huge fetuses and improve the prenatal diagnosis of fetal macrosomia to reduce the complications of childbirth and improve the quality of perinatal obstetric work is the focus.
