Research Progress of Traditional Chinese Medicine on Skin Pruritus in Maintenance Hemodialysis Patients and Related Pathogenesis Thinking

Abstract

The pathogenesis of skin pruritus in maintenance hemodialysis patients is complex, and modern medical treatment is facing a bottleneck. Based on the theory of “deficiency in origin and excess in superficiality,” traditional Chinese medicine has been deepening its understanding of the etiology and pathogenesis of this disease, and has formed a consensus based on spleen and kidney deficiency and mutual accumulation of dampness, turbidity, blood stasis and heat. On this basis, the external treatment of traditional Chinese medicine represented by traditional Chinese medicine fumigation / medicated bath and acupoint stimulation (auricular point, massage, scraping) shows definite curative effect and unique advantages, and the comprehensive combination scheme has become the trend of clinical research. However, the existing research is still insufficient in terms of theoretical depth, program standardization and mechanism of action. This paper systematically reviews the relevant literature, summarizes the evolution of the understanding of etiology and pathogenesis and the progress of treatment, and puts forward the introduction of the theory of “imbalance between Ying and Wei” to integrate the existing understanding and deepen the thinking of the theory of external treatment, in order to provide direction for future clinical and scientific research.
