Methods 22 patients undergoing elective surgery were divided into two groups randomly:group HVH and group IVH.After induction of anesthesia, blood was withdrawn via radialis artery while Ringer's lactate solution with threefold the volume of blood withdrawnor Dextran 40 with the same volume as blood withdrawnwas infused in big peripheral vena with identical speed.

选择22例外科择期手术病例，分为HVH和IVH两组，于全麻稳定后，经桡动脉采血，同时外周大静脉匀速输入3倍于采血量的乳酸钠林格液或等于采血量的右旋糖酐施行血液稀释。

Objective To compare the different effects between acute moderate hypervolemic hemodilution using Ringer's lactate solution and acute moderate isovolemic hemodilution using dextran 40 on coagulation mechanism,and to provide clinical basis for selecting optimal dilution.

目的：比较乳酸钠林格液扩容性急性血液稀释和低分子右旋糖酐等容性急性血液稀释对凝血机制的影响，为合理选择稀释液提供临床依据。
