目的观察妊娠晚期超声计量低羊水指数(AFI)产妇的各项围生期结局指标变化。方法选择近期住院的83例低AFI产妇,观察她们的围生期结局各项指标,并与175例同期住院分娩的正常AFI产妇(对照组)比较。结果低AFI组的剖宫产、胎儿窘迫、羊水污染、新生儿窒息和围产期儿死亡发生例数均明显多于对照组(P均<0.01~0.05)。结论超声计量低AFI是预示产妇围生期结局不良的理想指标。
Objective To observe the perinatal outcome changes of pregnant women with late-trimester ultrasonographic low amniotic fluid index (AFI). Methods A total of 83 low-AFI maternal women who were hospitalized recently were enrolled in this study. Their perinatal outcomes were observed and compared with those of 175 normal AFI mothers hospitalized during the same period of hospitalization (control group). Results The incidence of cesarean section, fetal distress, amniotic fluid contamination, neonatal asphyxia and perinatal death in the low AFI group were significantly higher than those in the control group (all P <0.01-0.05). Conclusion Ultrasound-weighted AFI is an ideal indicator of maternal perinatal outcome.
