The objective was to determine if maternal rest in the left lateral recumbent position increases the estimated fetal weight (EFW) in fetuses classified by the Delphi consensus as growth restricted (FGR) or small-for-gestational age (SGA).
This was a retrospective observational study of 265 fetuses classified as FGR or SGA using the Delphi consensus. After the diagnosis of FGR or SGA, the patient was asked to begin resting in the left lateral recumbent position during her waking hours for 2 weeks. The EFW was measured 2 weeks following maternal rest.
Of the 265 fetuses, FGR was identified in 56% (148/265) and SGA in 44% (117/265). Following maternal rest, the median values for the EFW percentile were significantly greater than at the time of diagnosis of FGR (18 vs. 5.96) and SGA (19 vs. 7.39). Following maternal rest, the EFW increased from < 10th percentile (100%) to greater than the 10th percentile in 70% of FGR and 82% of SGA fetuses.
Fetuses with growth restriction or who were small-for-gestational age significantly increased their weight from below to above the 10th percentile following 2 weeks of maternal rest.
确定按照德尔菲共识分类为生长受限（FGR）或小于胎龄儿（SGA）的胎儿，母体左侧卧位休息是否会增加其估计胎儿体重（EFW）。
这是一项对265例按照德尔菲共识分类为FGR或SGA的胎儿进行的回顾性观察研究。在诊断为FGR或SGA后，要求患者在清醒时间开始左侧卧位休息2周。在母体休息2周后测量EFW。
在265例胎儿中，56%（148/265）为FGR，44%（117/265）为SGA。母体休息后，EFW百分位数的中位数显著高于诊断FGR时（18对5.96）和SGA时（19对7.39）。母体休息后，70%的FGR胎儿和82%的SGA胎儿的EFW从低于第10百分位数增加到高于第10百分位数。
生长受限或小于胎龄的胎儿在母体休息2周后，其体重从低于第10百分位数显著增加到高于第10百分位数。
