摘要： 目的 调查现行感染控制管理制度下，血液透析机治疗前后表面污染情况及进行消毒擦拭前后的差别。 方法 在严格按照《北京市血液透析质量控制管理规范》实施感染控制管理的前提下，进行日常2个班次的透析治疗。依据《医院消毒卫生标准》GB 15982-1995要求，对上、下午透析前后33台血液透析机的台面及面板取样进行细菌培养，并依据《医院消毒卫生标准》GB 15982-1995标准评价其检测结果。 结果 所有样本总合格率96.2%，其中上、下午透析前合格率均为100%，上、下午透析后未擦拭前合格率分别为93.9%和90.9%。各班次透析前、后菌落计数对比差异有统计学意义(P＜0.05)；2班次之间进行消毒擦拭前后菌落计数对比差异无统计学意义(Z =-1.61,P＞0.05)，但是擦拭后的合格率达100%。 结论 《北京市血液透析质量控制管理规范》规定的透析治疗各班次之间擦拭消毒血液透析机是必要而且有效的。

Abstract: Objects To investigate the differences of the contamination on hemodialyzer surface before and after a hemodialysis session, and before and after the wipe and disinfection following the current administration rules for infection control. Methods The wipe and disinfection procedures defined in the Current Stipulation for Hemodialysis Quality Control were strictly carried out in the hemodialysis center, in which two sessions per hemodialyzer were conducted in a workday. Bacterial cultures were performed for samples taken from the 33 hemodialyzer before hemodialysis sessions in the morning and after the sessions in the afternoon. The bacterial culture results were evaluated following the published standards. Results The overall negative rate was 96.2%. Samples taken before dialysis sessions in the morning and in the afternoon were all negative, while those taken after dialysis sessions before wipe and disinfection were negative in 93.9% samples in the morning and in 90.9% samples in the afternoon. The number of bacterial colonies in samples taken before dialysis sessions was significantly different from that taken after sessions (P＜0.05). Although the number of bacterial colonies had no statistical difference between samples taken before and after the wipe and disinfection procedure, the negative rate reached to 100% after the procedure. Conclusion The wipe and disinfection procedure following the Current Stipulation for Hemodialysis Quality Control and performed between every hemodialysis session was proved to be essential and effective.
