Haemodilution in nine neonates resulted in significant mean (SEM) decrease of packed cell volume (0.67 (0.01) to 0.55 (0.01)) and increases in cardiac output (250 (16) to 308 (25) ml/min/kg) and blood flow velocities of the internal carotid artery and the coeliac artery (+20%). However, red cell flows in the aorta, carotid and coeliac arteries did not change during haemodilution, thereby indicating that haemodilution did not improve oxygen transport.
对9名新生儿进行血液稀释后，血细胞比容显著降低（平均值（标准误）从0.67（0.01）降至0.55（0.01）），心输出量增加（从250（16）增至308（25）ml/min/kg），颈内动脉和腹腔动脉的血流速度增加（+20%）。然而，在血液稀释过程中，主动脉、颈动脉和腹腔动脉中的红细胞流量并未改变，因此表明血液稀释并未改善氧输送。
