153例巨大胎儿分析

目的：探讨巨大胎儿的产前诊断及分娩方式，降低母婴并发症。方法：回顾分析153例巨大胎儿的诊断，分娩方式及并发症，并与单胎正常体重儿分娩情况进行比较。结果：巨大儿的发生与孕妇的体重，身高，孕周有关，巨大胎儿中双顶径（BPF）＋股骨长度（FL）＞16.5cm者占87．41％，剖宫产组较阴道分娩组新生儿窒息率及产伤机会均明显降低，巨大胎儿与正常体重儿相比难产率明显升高。结论：BPD＋FL＞16.5cm可做为产前诊断巨大胎儿的一项可靠指标，对巨大胎儿应避免困难的阴道助产，适当放宽剖宫产指征。

Analysis of 153 Fetal Macrosomia

Objective:To investigate the prenatal diagnosis and delivery mode of fetal macrosomia in order to decrease the complications in both mothers and neonates.Methods:153 cases of fetal macrosomia were analyzed.The diagnosis,delivery mode and complications of fetal macrosomia were recorded and the data were compared with those of nomal weight fetus.Results:Macrosomia was associated with maternal body weight and height,gestational weeks.Biparietal diameter (BPD)+femur length (FL)>16.5cm coverd 87.41% and the chance of asphyxia and getting hurt during cesarean section were less than those in vaginal delivery.The rate of dystocia in fetal macrosomia increased obviously as compared with that in normal body weight fetus.Conclusion:BPD+FL>16.5cm can be a reliable index for the diagnosis of fatal macrosomia.The difficult midwifery in vagina should be avoided and the index for cesarean section in fetal macrosomia should be widened.
