【摘要】 目的研究6%羟乙基淀粉和平衡液行高容性血液稀释时对血液成分的不同影响。方法20例胃切除术患者麻醉诱导后,分别输入6%羟乙基淀粉(HAES组)和平衡液(LR组)行高容性血液稀释(AHH)。于AHH前、AHH后15min及30min时测定Hb、Hct和Plt。结果HAES组AHH后15min及30min时的Hb及Hct较AHH前均显著降低(P<0.05)。LR组AHH后15min时的Hb及Hct较AHH前显著降低,30min时的Hb及Hct较15min时明显回升(P<0.05)。两组AHH前后Plt变化无明显意义(P>0.05)。结论HAES和LR行高容性血液稀释均能降低Hb及Hct,但HAES的作用更持久,更适合需要。更多还原

【Abstract】 Objective To observe the efficacy of hydroxyethyl starch and equilibrium liquid on acute hypervolemic hemodilution.Methods 20patients scheduled for gastric operation were randomly divided into two groups.The patients in two groups were taken acute hypervolemic hemodilution with hydroxyethyl starch(HAES group)and equilibrium liquid(LR group)after induction of anesthesia.Hb,Hct and Plt were detected before AHH and15min,30min after AHH.Results Hb and Hct in group HAES15min and30min after AHH were significantly lower than those before AHH(P<0.05).Hb and Hct15min after AHH were significantly lower than those before AHH in group LR(P<0.05).But they got higher30min after AHH.The changes of Plt in the two groups had no obvious difference(P>0.05).Conclusion AHH with hydroxyethyl starch was more effective than that with equilibrium liquid.[更多还原
