Abstract: Macrosomia is one of the common fetal complications in obstetrics. The associated high risk factors include high pre-pregnancy body mass index （BMI），excessive increase of body weight during pregnancy and gestational diabetes mellitus. Macrosomia raises the rate of cesarean section. The incidence of severe perineal tear，shoulder dystocia，brachial plexus injury，neonatal asphyxia，death and other adverse maternal and infant outcomes increases，too. Accurate clinical evaluation of macrosomia and timely termination of pregnancy may avoid complications and improve maternal and infant outcomes. The clinical and ultrasonic evaluation and prediction methods of macrosomia，the intervention methods of induced labor and pregnancy outcome were discussed in the current paper.

摘要： 巨大胎儿（macrosomia）是产科常见的胎儿并发症之一，与孕前体重指数（BMI）较高、孕期增重过量、妊娠期糖尿病等高危因素密切相关，会增加剖宫产率，造成包括会阴严重撕裂、肩难产、臂丛神经损伤、新生儿窒息或死亡等多种不良母儿结果。针对巨大胎儿进行准确的临床评估和适时引产终止妊娠有可能避免相关并发症，改善母儿结局。文章总结了巨大胎儿的临床及超声评估和预测方法，并针对催引产干预方法及妊娠结局进行了论述。
