摘要
本文分析我院近十年中五个年度分娩的664例巨大胎儿,其发生率为6.88%,发生率逐年上升,1987年为1975年的4.37倍,且超巨大胎儿逐年增加,初产妇占绝对优势(91.57%),这是当前我国巨大胎儿特征。巨大胎儿的产前诊断可采用宫高腹围值来估计,本文提出初产妇宫高腹围值≥130cm 为巨大胎儿的诊断。并提示 B 超测定胎头双顶径≥9.4cm 应警惕巨大胎儿的可能性。巨大胎儿不仅头围、胸围较正常体重儿大,且头颅骨也较硬、不易变形,分娩过程中,尤其在初产妇发生梗阻性分娩的可能性明显增加,应适当放宽剖腹产指征。
Six hundred and sixty-four fetal macrosomiae in five separate years out of therecent decade in our hospital were analyzed.The incidence of fetal macrosomia was6.88% which was increasing year by year.The incidence in 1987 was 4.37 times thanthat in 1975.Furthermore,the fetal super-macrosomia was increasing year by year.One of the characteristics of fetal macrosomia in our country was the overwhelmingmajority of the condition in primipara(91.57%).The antenatal diagnosis of fetal macrosomia was estimated by measuring the valueof SF and AC.It was suggested that the diagnosis of fetal macrosomia should beconsidered when the value was≥130cm and BPD≥9.4cm as measured by B-ultrasound.Not only the circumferences of the cranium and thorax of fetal macrosomia were lar-ger than those of normal,but also the cranium was harder and invariable in shape.The possibility of obstruction dystocia in labor was evidently increasing,especiallyin primipara.Therefore,the indications of cesarean section was necessary to be app-ropriately widened.
