摘要：目的 探讨6%中分子羟乙基淀粉和4%的琥珀明胶用于体外循环预充时，对患者凝血功能的影响。方法 选择38例瓣膜替换术的患者，随机分为贺斯组和佳乐施组。分别在麻醉前及鱼精蛋白中和后30min取静脉血1ml，运用Sonoclot 凝血及血小板功能分析仪测定凝血功能，测定参数有：激活凝血时间(SonACT)、凝血速率(Clot Rate)、血小板功能(Platelet Function)，并描绘凝血过程曲线图。结果 两组间激活凝血时间、血小板功能术前术后均无显著性差异，但术后凝血速率贺斯组明显小于佳乐施组。结论 佳乐施与贺斯1000ml用于预充时对凝血功能无显著影响，但与佳乐施相比，贺斯对凝血通路中纤维蛋白形成速率抑制相对较强。

    Abstract: OBJECTIVE To observe the effect of 6% hydroxyethel starch(HES) and 4% succinylated gelatin(GEL) for priming on coagulation in the operation with cardiopulmonary bypass(CPB). METHODS Thirty-eight patients ondergoing valve replacement were divided randomly into two groups: Group HES and Group GEL. The SonACT, Clot Rate and Platelet Function were measured in the two groups before anaesthesia and 30 minutes after protamine was neutralized using the Sonoclot Analyzer. RESULTS There is no significant difference between these two groups before and after CPB in terms of coagulation data: SonACT and Platelet Function ( P>0.05), but the clot rate in the GEL group decreased significantly after CPB ( P<0.05 ). CONCLUSION There is no significant effect on coagulation when 1000ml HES and GEL were used for priming, but the effect of restraining the fibrin formation is stronger in HES. ......
