Abstract: Maintenance hemodialysis (MHD) is an important renal replacement therapy for end-stage renal disease. Intradialytic hypotension (IDH) is a common complication in MDH patients. IDH may cause many adverse events and affect the quality of life and the prognosis of the patients. The discovery of high-risk factors for IDH is essential to the early identification of IDH. The IDH prediction models integrate multiple risk factors, can better predict the occurrence of IDH, and thereby improve the prognosis of MHD patients. This article discusses and summarizes the definition of IDH, risk factors for IDH, the types of prediction models, and the prediction models of IDH in China and foreign countries, in order to provide references for the construction of suitable prediction models for IDH.

Key words: Hemodialysis, Intradialytic hypotension, Risk factors, Prediction model
