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.“,”We analysis 63 giant fetus (weight ≥4kg) deliveried in our hospital from Januny 1, 1996-December 31, 1997. Our results showed that giant fetus was related to over-nutrition and lers-movement and that mother and baby complications of giant fetus at stagcs of labo rsuch as cephala pelvic disproportion, shoulder dystocia, asphyxia neonatorum and postpartum hemorrhage were more than those of normal weight fetus. There fore it is important that early diagnosis and prevention of gaint fetus should be made at antepartum in order to reduce complication and decrease mortality and morbility of gaint fetus in prenatal period.
