Nowadays, there are no effective methods to alleviate the process from the initial CRF to ESRD. In clinic, the integrated therapy of traditional Chinese and western medicine is frequently adopted for CRF in combination with hemodialysis, but in the process of treatment, traditional Chinese medicine(TCM) nursing plays a key role. This article mainly explored the key points of common syndromes, TCM nursing methods and health guidance of CRF in order to further develop the advantages of TCM, improve its efficacy and standardized its nursing behavior.展开更多
