Recent literature has suggested that total intrauterine volume (TIUV) estimation is useful fir distinguishing normal from growth-retarded fetuses. One hundred seventy-nine measurements of TIUV were obtained from the ultrasonograms taken between 21 and 40 weeks of gestation in 140 patients who delivered average birthweight babies. We constructed a mean curve for TIUV with upper and lower 2.5 and 10% tolerance limits and later evaluated the TIUV's of 16 patients with growth-retarded fetuses. Nine of these fetuses had birthweights below the fifth percentile for gestational age, and in each of these pregnancies the TIUV ultimately fell below the lower 2.5% tolerance limit.
近期文献表明，估计子宫内总体积（TIUV）有助于区分正常胎儿与生长受限胎儿。对140名分娩出平均体重婴儿的患者在妊娠21至40周期间所做的超声检查进行了179次TIUV测量。我们构建了TIUV的均值曲线以及上下2.5%和10%的耐受限度，随后对16名生长受限胎儿的TIUV进行了评估。其中9名胎儿的出生体重低于相应孕周的第五百分位数，在这些妊娠中，每个妊娠的TIUV最终都低于较低的2.5%耐受限度。
