呼吸气体，酸碱平衡，乳酸盐和血红蛋白浓度测定14个胎儿的血液样本之间的17和21周的妊娠。在进行产前诊断的胎儿镜检查时获得样本。结果与两个参考组进行了比较：（a）4例在妊娠32-36周时进行胎儿脐带血采样的患者，和（B）10例在35-39周时进行择期剖宫产的患者。PO 2和氧饱和度显着较高，血红蛋白浓度较低，在中期妊娠胎儿。酸碱平衡无显著差异。母亲和胎儿血红蛋白浓度之间存在显著相关性。胎儿血液的氧亲和力与氧饱和度低于90%的足月胎儿的氧亲和力无显著差异。
Respiratory gases, acid-base balance, and lactate and hemoglobin concentrations were measured in 14 fetal blood samples between 17 and 21 weeks of gestation. The samples were obtained at the time of fetoscopy performed for prenatal diagnosis. Results have been compared with two reference groups: (a) 4 patients in whom fetal cord blood sampling was performed at 32–36 weeks of gestation, and (b) 10 patients at the time of elective cesarean section, 35–39 weeks. PO2and oxygen saturations were significantly higher and hemoglobin concentration lower in the mid-gestation fetus. Acid-base balance was not significantly different. There was a significant correlation between maternal and fetal hemoglobin concentrations. The oxygen affinity of fetal blood was not significantly different from that described for term fetuses with a oxygen saturation of less than 90%.
