目的 设计一种连续性肾脏替代治疗（continuous renal replacement therapy,CRRT）专用治疗车,并探讨其应用效果。方法 本CRRT专用治疗车由带万向轮的车主体、操作台面、垃圾桶挂放处、锐器盒放置处等组成,将CRRT治疗过程中所需物品放在CRRT治疗车中,置于床边。选取2022年8月—10月浙江省某三级甲等医院重症医学科行CRRT的患者为研究对象,共行70次CRRT治疗,按照随机数字表进行分组,试验组及对照组各35次。比较两组物品取用便利度、责任护士满意度、质控护士满意度的差异。结果 试验组物品取用便利度评分为4（4,5）分,对照组3（2,3）分;试验组责任护士满意度评分为4（4,5）分,对照组3（2,3）分;试验组质控护士满意度评分为4（4,4）分,对照组2（2,3）分,两组比较差异均有统计学意义（P<0.001）。结论 CRRT专用治疗车可提高操作效率和护士工作满意度。

Objective To design and explore the application effect of a new special vehicle for continuous renal replacement therapy（CRRT)in critically ill patients. Methods This CRRT specialized treatment vehicle consists of a vehicle body with universal wheels,an operating platform,a garbage bin hanging area,and a sharp tool box placement area. The necessary items during the CRRT treatment process are placed in the CRRT treatment vehicle by the bedside. Patients who received CRRT from the Intensive Care Unit of a Grade-III hospital in Zhejiang Province from August 2022 to October 2022 were selected as the research objects. A total of 70 CRRT operations were performed. According to the random number table,the experimental group and the control group were 35 times respectively. The convenience of item retrieval,the satisfaction of responsible nurses and the satisfaction of quality control nurses were compared between the two groups. Results The convenience score of the experimental group was 4（4,5)points,while the control group was 3（2,3)points. The satisfaction score of the responsible nurses in the experimental group was 4（4,5)points,while the control group was 3（2,3)points. The satisfaction score of the quality control nurses in the experimental group was 4（4,4)points,while the control group was 2（2,3)points. The differences were statistically significant between the two groups（P<0.001）. Conclusion The new CRRT special treatment vehicle can effectively increase the convenience,and improve the satisfaction of nurses.
