The amniotic fluids of 7 pregnant women with Rh-isoimmunization were examined. On the basis of the data of this investigation as well as of the clinical and ultrasound data intrauterine blood transfusions were made in fetuses--from 4 to 8 in number. Forty two spectrophotometric analyses were made in all, but the amniotic fluids were examined before intrauterine blood transfusions as well as before the performance of each subsequent blood transfusion. The authors found changes in the characteristic of the amniotic fluid after intrauterine blood transfusion, which were manifested by the fact that the pigment peak of delta 450 nm was reduced, but the peak of delta 410 nm was increased. In connection with these findings after intrauterine blood transfusions delta 450 nm lost its diagnostic and prognostic value. delta 410 nm before intrauterine blood transfusions manifested gravity of fetal hemolytic disease. After intrauterine blood transfusions its increase was due to blood transfusions and accumulation of methemoglobin in the amniotic fluid.
对7名Rh血型免疫孕妇的羊水进行了检查。根据本研究数据以及临床和超声数据，对胎儿进行了宫内输血，数量为4至8例。总共进行了42次分光光度分析，但在宫内输血前以及每次后续输血前都对羊水进行了检查。作者发现宫内输血后羊水特征发生了变化，表现为450nm处的色素峰降低，但410nm处的峰升高。鉴于宫内输血后的这些发现，450nm失去了其诊断和预后价值。宫内输血前410nm表明胎儿溶血病的严重程度。宫内输血后其升高是由于输血以及羊水中亚铁血红蛋白的积累。
