自动密闭式预冲法与手动密闭式预冲法在血液透析中的对比研究

The comparative study of automatic closed and manual closed pre-rinse method in hemodialysis

目的:探讨自动密闭式预冲法与手动密闭式预冲法在血液透析中的临床应用效果。方法:选取80例维持性血液透析患者,采用自身前后对照的方法在血液透析中对每例患者采用自动密闭式预冲法与手动密闭式预冲法两种方法,比较两种方法气泡残留、不溶性微粒直径>10μm和直径>25μm的微粒数量、预冲量合格率以及操作平均用时。结果:两种方法预冲的气泡残留比较,差异无统计学意义(t=-1.165,P>0.05);不溶性微粒直径>10μm和直径>25μm微粒数量比较,差异无统计学意义(t=0.474,t=-1.710;P>0.05);两种方法操作平均用时和预冲量合格率比较,自动密闭式预冲法明显优于手动密闭式预冲法,两种方法比较差异有统计学意义(x^2=77.037,P<0.01)。结论:自动密闭式预冲法提高护理标准化操作合格率,减少操作时间。

Objective: To discuss the clinical effect between automatic closed and manual closed pre-rinse method in hemodialysis. Methods: 80 maintenance hemodialysis patients were selected, and the self-control study was used to compare a series of indicator, such as the residual bubble test score, the number of insoluble particles (diameter >10 μm, and >25μm), the qualified rate of pre-rinse quantity and average operation time between manual closed and automatic closed pre-rinse method. Results: There was no significant difference in the residual bubble test score of two methods(t=-1.165, P>0.05); there was no significant difference in the number of insoluble particles (diameter >10 μm and>25 μm) (t=0.474, t=-1.710; P>0.05). There was significant difference in the qualified rate of pre-rinse quantity and average operation time of two methods (x2=77.037, P<0.01). Conclusion: The method of automatic closed pre-rinse can increase the qualified rate of nursing standardization and reduce the operation time.
