本文前瞻性分析了333例妊娠≥4l周的分娩前3天内羊水量超声测定和妊娠结局的关系,随羊水量下降,过熟综合征的发生率增加,A’pgar低分率的变化不大。研究组围产死亡率9‰,新生儿窒息率5.1%,结果显示超声羊水量测定是佶计过期妊娠胎盘功能的较好指标。本文讨论了不同羊水平段的临床处理方案。 This prospective analysis of 333 cases of pregnancy ≥ 41 weeks before delivery three days before delivery of amniotic fluid ultrasound and pregnancy outcomes, the relationship with the amniotic fluid volume, the incidence of over-mature syndrome, A’pgar low scores did not change much . The study group of perinatal mortality rate of 9 ‰, neonatal asphyxia rate of 5.1%, the results show that the determination of ultrasound amniotic fluid count is a better indicator of placental function overdue gestational age indicators.
