Objective:To retrieve, evaluate, and integrate the best evidence for prevention of hemodialysis catheter thrombosis, so as to provide evidence-based basis for catheter thrombosis prevention in hemodialysis patients.Methods:Guidelines, clinical decisions, evidence summaries, systematic reviews, and expert consensus on the prevention of hemodialysis catheter thrombosis were systematically searched on Guidelines International Network, Scottish Intercollegiate Guidelines Network, Agency for Healthcare Research and Quality, Registered Nurses' Association of Ontario, National Institute for Health and Clinical Excellence, UpToDate, British Medical Journal (BMJ) Best Practice, Joanna Briggs Institute Evidence-Based Health Care Center Database, European Renal Association, National Kidney Foundation, UK Kidney Association, Canadian Society of Nephrology, Japanese Society for Dialysis Therapy, Medlive, Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure, VIP, and Wanfang Data and Chinese Biomedical Database. The search period was from database establishment to March 31, 2023. Investigators conducted quality evaluations separately and extracted and summarized evidence based on the theme.Results:A total of 16 articles were included, including five clinical decisions, four guidelines, two evidence summaries, and five expert consensuses. Finally, 15 best pieces of evidence were formed, including four themes of indwelling dialysis catheters, anticoagulation strategies, flushing and sealing techniques, and daily management.Conclusions:Nursing staff should choose the best evidence for preventing thrombosis in hemodialysis catheters based on clinical situations, reduce the occurrence of catheter thrombosis, extend the usage time of catheters, and improve patient outcomes.

Objective:To design a continuous renal replacement therapy (CRRT) waste liquid bag disposal vehicle and explore its effectiveness.Methods:In February 2024, convenience sampling was used to select 100 waste liquid bags generated during CRRT in the ICU of Zhejiang Provincial Hospital of Chinese Medicine as research subjects. The waste liquid bags were divided into an observational group ( n=50) and a control group ( n=50) using a random number table method. The control group was treated using usual method, while the observational group was treated using a CRRT waste liquid bag disposal vehicle. The emptying time of a single bag of waste liquid, the number of splashes per unit area, and operator satisfaction were compared between two groups. Results:The emptying time of a single waste liquid bag in the observational group was lower than that in the control group [ (38.34±1.98) vs. (315.46±11.23) s, P<0.01]. The number of splashes per unit area of 5 cm × 5 cm in the observational group was less than that in the control group [ (0.28±0.09) vs. (8.62±0.64), P<0.01]. The operator satisfaction score of the observational group was higher than that of the control group [ (4.88±0.05) vs. (1.44±0.10) points, P<0.01] . Conclusions:The CRRT waste liquid bag disposal vehicle can reduce the emptying time of waste liquid bags and the pollution to the surrounding environment during the discharge process, improve operator satisfaction, and is worthy of promotion in clinical practice.
