产前能否准确预测胎儿体质量,及早发现巨大儿,对选择分娩方式、避免母亲软产道损伤,减少产后出血,减少感染,减少胎儿产程中肩难产、臂丛神经损伤、锁骨骨折、颅内出血、新生儿窒息等具有十分重要的意义。及早发现胎儿生长受限,可以减少围生儿病死率、降低胎儿出生缺陷发生率、可早诊断、早干预减少新生儿后遗症的发生。现对对胎儿体质量估计的众多的测量方法进行综述。 Prenatal can accurately predict the quality of the fetus, early detection of huge children, on the choice of mode of delivery, to avoid maternal maternal injury, reduce postpartum hemorrhage, reduce infection, reduce fetal labor in the shoulder dystocia, brachial plexus injury, clavicular fracture, intracranial hemorrhage , Neonatal asphyxia is of great significance. Early detection of fetal growth restriction, can reduce perinatal mortality and reduce the incidence of fetal birth defects, early diagnosis and early intervention to reduce neonatal sequelae. A review of numerous measurement methods for estimating fetal body mass is now available.
