为了减少术中对异体血液或血液制品的需求，急性等容血液稀释越来越得到临床广泛的应用。由于晶体液和胶体液组成成分的理化性质不同，所以在对细胞外液的影响以及维持适宜的血容量上二者所起的作用也不同。至今在血液稀释中容量扩充剂的选择上仍然存在许多争论。本实验对家兔
In order to reduce the need for intraoperative blood or blood products, acute normovolemic hemodilution is getting more and more widely used clinically. Because of differences in physical and chemical properties between the crystalline and colloidal fluid components, the effects on both the extracellular fluid and the maintenance of adequate blood volume are also different. So far there is still much debate about the choice of volume extenders in hemodilution. This experiment on rabbits
