超声检查羊水量减少已作为不良围产结局的一个预测指标。羊水过少（即羊水指数ＡＦＩ≤５ｃｍ）可增加围产期死亡率及胎儿窒息的剖宫产，胎粪吸入，低Ａｐｇａｒ评分及宫内生长发育迟缓（ＩＵＧＲ）的危险性。但是对于ＡＦＩ临界值的临床意义研究并不多。最近有研究提示ＡＦＩ
Ultrasound to reduce the amount of amniotic fluid has been used as a predictor of adverse perinatal outcomes. Oligohydramnios (amniotic fluid index AFI ≤ 5cm) can increase perinatal mortality and fetal asphyxia cesarean section, meconium aspiration, low Apgar score and intrauterine growth retardation (IUGR) risk. However, there are not many studies on the clinical significance of AFI. Recent research suggests AFI
