Abstract: Objectives Periodic maintenance and preventive repair for hemodialysis dialyzers are critical to ensure high quality of hemodialysis, efficient use of dialyzers, reduction of consumable parts and running cost, and untoward response control in patients due to dialyzer dysfunction. Methods Through the strict rules for management of dialyzers, the training for nurses working in hemodialysis center, and the enforced responsibility and technical abilities of the technicians, passive repair after breakdown of dialyzers can be changed to periodic maintenance and preventive repair before the presence of troubles in dialyzers. Results
After the implement of periodic maintenance and preventive repair, the breakdown rate of dialyzers reduced significantly, the cost for repair and performance decreased, and daily work in hemodialysis center could be carried out more efficiently. Conclusion Periodic maintenance and preventive repair are important for dialyzers working in a safe and best condition. Consequently, the running cost can be reduced, and the hemodialysis center can be run smoothly with lower incident rate and higher satisfaction from patients.
