Objective To search,evaluate and summarize the best evidence of self volume-management for patients with chronic heart failure（CHF） based on the situation-specific theory of heart failure self-care. Methods The computer decision support systems,guideline websites,databases were systematically searched to collect the literature related to self volume-management in CHF patients. The retrieval period is from the establishment of databases to May 4th,2021. 2 researchers assessed the quality of the included literature independently and extracted the evidence. Results A total of 9 articles were included,including 7 clinical practice guidelines and 2 expert consensuses. A total of 13 pieces of evidence have been obtained from 3 aspects including self volume-management maintenance,symptom perception of volume overload,and volume overload management. Conclusion The best evidence should be used to help CHF patients maintain a balance of volume status,recognize changes in volume status as soon as possible,and learn some skills to respond appropriately to volume overload.

Fluid management is a prevention and management strategy of heart disease. The aim of this strategy is to prevent and control fluid retention in patients with heart failure,thereby reducing the re-hospitalization rate and mortality,and improving their quality of life. This paper summarizes the specific content and development form of liquid management,and points out the defects and improvement direction of current liquid management research,aiming to arouse the attention of nurses on fluid management of patients with heart failure,and to explore a suitable fluid management model for them.
