1023死产和活产婴儿谁住不到72小时的体重相比，主要器官的重量比。从孕20 ~ 43周，每增加2周计算一次比值，清楚地描述了妊娠后半期胎儿器官的相对生长情况。心脏和肾脏的比值在整个妊娠期间几乎保持不变。胸腺和脾脏的比例在妊娠20至30周之间增加，然后趋于恒定，尽管脾脏的比例在最后6周略有下降。孕20 ~ 30周肝、肺、肾上腺比值下降，随后又下降。在整个检查期间，脑的比率下降非常缓慢。具有实际重要性的观察结果是，妊娠30周后，所有器官重量/体重比几乎保持不变。妊娠30 - 43周的近似平均器官重量/体重比为：心脏0.007、肺0.02、脾0.003、肝0.04、肾0.01、肾上腺0.003、胸腺0.004和脑0.13。将平均比值乘以总体重。在手头没有正常器官重量图表的情况下，可以计算特定胎儿器官的近似平均重量。
Ratios for major organ weights compared with bodyweights of 1023 stillborn and liveborn babies who lived less than 72 h are presented. The ratios were calculated for 2 week increments of gestational age from 20 to 43 weeks and clearly depict the relative growth of fetal organs during the last half of pregnancy The ratios for heart and for kidneys were virtually constant for the whole period of gestation examined. The ratios for thymus and spleen increased between 20 and 30 weeks gestation and then became constant, although the ratio for the spleen dropped slightly during the last 6 weeks. The ratios for liver, lungs and adrenals decreased between 20 and 30 weeks gestation, and then steadied. The ratio for brain declined very slowly throughout the period examined. An observation of practical importance was that all organ weight/bodyweight ratios were virtually constant after 30 weeks gestation. Approximate mean organ weight/bodyweight ratios between 30 and 43 weeks gestation were: heart 0.007, lungs 0.02, spleen 0.003, liver 0.04, kidneys 0.01, adrenals 0.003, thymus 0.004 and brain 0.13. By multiplying the mean ratio by the total bodyweight. the approximate mean weight for a particular fetal organ can be calculated in situations where charts of normal organ weights are not at hand.
