The umbilical venous oxygen and carbon dioxide tensions, pH, lactate and glucose concentrations, nucleated red cell (erythroblast) count, and haemoglobin concentration were measured in 38 cases of intrauterine growth retardation in which fetal blood sampling was performed by cordocentesis. The oxygen tension was below the normal mean for gestational age in 33 cases; in 14 it was below the lower limit of the 95% confidence interval for normal pregnancies. The severity of fetal hypoxia correlated significantly with fetal hypercapnia, acidosis, hyperlacticaemia, hypoglycaemia, and erythroblastosis. These findings indicate that "birth asphyxia" is not necessarily due to the process of birth.
对38例宫内生长迟缓病例进行了脐静脉氧分压、二氧化碳分压、pH值、乳酸和葡萄糖浓度、有核红细胞（成红细胞）计数及血红蛋白浓度的测定，这些病例均通过脐静脉穿刺术采集胎儿血样。33例病例的氧分压低于胎龄正常均值；14例低于正常妊娠95%置信区间的下限。胎儿缺氧的严重程度与胎儿高碳酸血症、酸中毒、高乳酸血症、低血糖症和成红细胞增多症显著相关。这些发现表明，“出生窒息”不一定是由出生过程导致的。
