半自动和全自动透析器复用方式对透析器复用效果的影响

目的 探讨半自动和全自动透析器复用方式对透析器复用效果的影响.方法 将1728支可重复使用的透析器随机分为半自动复用组和全自动复用组各864支,观察2组透析器冲洗、检测时间、使用灭菌剂成本及热原反应、透析器破膜发生率、透析器重复检测数.结果 半自动复用组透析器冲洗、血室容积检测和压力测试时间分别为(26.443±3.237),(2.172±0.128),(2.157±0.090)min,灌注3.5%伦拿连灭菌剂成本为(1.698±0.107)元,支,共有499支和243支透析器需重复进行血室容积检测及压力检测,重复检测率达57.755%和28.125%;全自动复用组透析器冲洗、血室容积检测和压力测试时间为(5.793±0.193),(1.257±0.118),(1.110±0.076)min,透析器检测均能1次完成,灭菌剂成本(9.330±0.138)元/支,2组透析器用于血液透析均未见热原反应及透析器破膜发生.结论 半自动复用组在灌注过程中能有效节省灭菌剂成本.但透析器冲洗时间长、缺乏配套检测装置,检测费时、数据不易读取,透析器重复检测率高;而全自动复用组透析器冲洗、检测方便,但消耗灭菌剂成本高,设备投入昂贵,透析中心需配置合理数量才能满足临床需求.

Comparative study on the effects of automatic and semi-automatic hemodialyzer reuse

Objective To explore the influence of automatic and semi-automatic hemodialyzer reuse method on hemodialyzer reuse effect. Methods 1728 dialyzers were randomly divided into automatichemodialyzer reuse group and semi- automatic hemodialyzer reuse group with 864 dialyzers in each group. Thetime of douching and testing, the cost of sterilization,the frequency of the pyrphgen reaction,the broken dialyzer membrane and re-examined dialyzer between the two groups were measured. Results The time of douching dialyzer, testing of total cell volume and pressure in the semi- automatic hemodialyzer reuse group was (26.443±3.237), (2.172±0.128) and (2.157±0.090) minutes respectively,while the automatic hemodialyzer reuse group was (5.793±0.193), (1.257±0.118) and (1.110±0.076) minutes respectively. The frequency of re-examined dialyzer in testing total cell volume and pressure was 499(57.755%), 243(28.125%) respectively. At the same time, all dialyzer in semi-automatic hemodialyzer reuse group could be examined successfully at a time. The cost of sterilization in automatic henmdialyzer reuse group was (9.330±0.138)yuan. No pyrogen reaction and broken dialyzer membrane happened. Conclusions The semi-automatic bemodialyzer reuse group can retrench cost during perfusion,but consumes long douching time, lacks matching detection equipment, difficult to detect, and is not easy to read data and has high re- examination rate. while in the automatic hemodialyzer group, it is convenient of douching and detection, but the cost of sterilization and equipment is high, and clinical demand can be fulfilled only when the dialysis center can allocate reasonable number of the machines.
