【摘要】 目的 比较血浆置换术中采用BD密闭式静脉留置针技术与常规静脉穿刺出现不良反应的差异性，探讨BD密闭式静脉留置针技术在血浆置换术中应用的临床效果。方法 将236例需行血浆置换的患者随机分为A和B两组，A组采用BD静脉密闭式留置针穿刺(120例)，B组采用普通静脉穿刺针穿刺(116例)。结果 A组静脉炎2例，液体外渗9例，其他不良反应3例；B组静脉炎8例，液体外渗18例，其他不良反应4例。A组不良反应发生率为11.7%，B组不良反应发生率为22.6%，两组比较有统计学意义，P<0.05。结论 血浆置换术中采用BD密闭式静脉留置针技术可降低穿刺部位不良反应的发生率。

    【Abstract】 Objective To compare the variability of adverse effects between BD closed tightly type detaining venepuncture and ordinary scalp venepuncture,and investigate the clinical effects applying BD closed tightly type detaining venepuncture in plasmapheresis.Methods 236 cases need plasmapheresis were randomly divided into A group and B group.The A group adopted BD closed tightly type intravenous detaining needle (120 cases) and the B group adopted ordinary scalp venepuncture (116 cases).Results Therehave 2 cases phlebitis,9 cases fluid exosmose and 3 cases other adverse effects in A group; Therehave 8 cases phlebitis,18 cases fluid exosmose and 4 cases other adverse effects in B group.The incidence rate of adverse effect was 11.7%in A group and 22.6%in B group,there was statistical significance compared two groups (P<0.05).Conclusion It was could to cut down that incidence rate of punctura place by BD closed tightly type detaining venepuncture in plasmapheresis. ......
