Abstract: Objective  To analyze the research status, development trend, research hotspots and frontiers of renal dialysis hyperkalemia in China.  Methods  CiteSpace literature analysis software was used to visually analyze the relevant literature on renal dialysis hyperkalemia collected from CNKI, Wanfang and VIP from 2000 to 2022. The maps were then downloaded for analyses.  Results  A total of 397 relevant research articles were included. The overall number of papers published showed an upward trend. The average annual number of papers published after 2011 (20.4 papers/year) was about twice that in the previous 10 years (12 papers/year). The high-frequency keywords were arrhythmia, diet control, purification equipment, treatment, and drugs related increase of blood potassium in the 10 years before 2010, and became ECG, health education and nursing quality in the 10 years after 2010, Keyword analysis showed that the research hotspots were first aid-related severe arrhythmia, ECG changes, survival time, and the importance of dietary restriction as the intervention measure in the first 10 years, and became health education, quality of care, and monitoring the presence of hypokalemia in the 10 years after 2010. In recent years, multicenter collaboration studies among high-level institutions have revealed the epidemiological characteristics of hyperkalemia; nursing intervention, chronic hyperkalemia and quality of life became the keywords and research frontiers.  Conclusion  In the past 20 years, the research on hyperkalemia in renal dialysis patients has been changed from rescue, diagnosis and treatment to prevention, nursing intervention, and improvement of quality of life. Currently, comprehensive management model is emphasized, including standardizing the treatment process of acute hyperkalemia and the early management of chronic hyperkalemia. In the future, exploring better health education model and promoting caregivers as the main body of intervention will be the hotspots and frontiers of the research on renal dialysis hyperkalemia.
