PURPOSE
To study the effect of decreased estimated fetal weight (EFW) percentiles in appropriate for gestational age fetuses.
METHODS
This retrospective cohort study included women who had second and third trimester ultrasound examinations. Delivery and neonatal outcomes of pregnancies with decreased EFW of ≥ 30 percentiles in EFW between ultrasound examinations (decreased growth group) and those without such a decrease (control group) were compared. Deliveries with EFW or birthweight below the 10th percentile were excluded.
RESULTS
Among 1610 deliveries, 57 were in the decreased growth group and 1553 in the control group. Maternal characteristics did not differ between the groups except for higher rate of nulliparity in the decreased growth group. We found similar rates of Category II/III monitoring, cesarean deliveries due to non-reassuring fetal heart rate and adverse neonatal outcomes. Neonatal birthweight was lower in the decreased growth group as compared to controls.
CONCLUSIONS
This study did not find association between the group of appropriate for gestational age fetuses with decreased growth, with adverse outcomes.
目的
研究适用于胎龄胎儿估计胎儿体重（EFW）百分位数降低的影响。
方法
本回顾性队列研究纳入了进行过中晚期超声检查的孕妇。比较了超声检查中 EFW 减少≥30 百分位（生长减少组）和没有这种减少的 EFW（对照组）的妊娠的分娩和新生儿结局。排除了 EFW 或出生体重低于第 10 百分位数的分娩。
结果
在 1610 次分娩中，57 次在生长减少组，1553 次在对照组。两组孕妇的特征除生长减少组的初产妇比例较高外，无差异。我们发现 II/III 类监测、因胎心监护不满意而行剖宫产和不良新生儿结局的发生率相似。与对照组相比，生长减少组新生儿出生体重较低。
结论
本研究未发现适用于胎龄胎儿生长减少与不良结局之间存在关联。
