下载后可任意编辑不同血浆代用品对红细胞聚集性的影响【摘要】 目的 比较不同血浆代用品对红细胞聚集性的影响。方法 分别从 20个单位的红细胞悬液中各取血 40 ml，平均分为四份，每份 10 ml，分别加入等容积的乳酸钠林格注射液、4%人血白蛋白、4%琥珀酰明胶注射液和 6%羟乙基淀粉 200/注射液中。混匀后测各组红细胞压积，血红蛋白浓度和血气，于室温下用魏氏法测 10 min、20 min、30 min、60 min 血沉值，余血离心后取上清测血浆粘度和血浆胶体渗下载后可任意编辑透压。结果 G 组和 H 组各时点血沉值均高于 L 组和 A 组，差异有显着性；G 组和 H 组比较，G 组各时点血沉比 H 组快，差异有显着性。形态学变化可见 G 组和 H 组红细胞聚集明显。结论 4%琥珀酰明胶注射液和 6%羟乙基淀粉 200/注射液均促进红细胞聚集，又以 4%琥珀酰明胶更为显着。【关键词】 红细胞聚集性；血沉；白蛋白；琥珀酰明胶；羟乙基淀粉 Effects of Plasma Replacement Fluids on Erythrocytes Aggregation下载后可任意编辑 Abstract: OBJECTIVE To ivestigate aggregation of erythrocytes in different plasma substitutes. METHODS 40ml erythrocyte suspension taken from 20 units packed red blood cells were divided into four parts and mixed respectively with equal volume sodium lactate Ringer‘s injection，4% albumin，4% fluid succinylated gelatin and 6% hydroxyethyl starch. Erythrocyte 下载后可任意编辑sedimentation rates(ESR) were measured affter 10 minutes,20 minutes,30 minutes,and 60 minutes at room temperature using Westergren‘s method. The colloid osmotic pressure (COP) and plasma viscosity were measured at same time. The morphological changes of erythrocyte was observed by light microscope. RESULTS The ESR were extremely higher in gelatin and hydroxyethyl starch 下载后可任意编辑and this increase was significant when compared with the other fluids. The ESR in gelatin is higher when compared with hydroxyethyl starch. The ESR in albumin and sodium lactate Ringer‘s injection were low and there...
