Abstract: 【Abstract】The incidence of renal disease is increasing nowadays in China; as a result, the treatment burden for end-stage renal disease patients is greatly increased. Hemodialysis plays an important role in renal replacement therapy. Intradialytic hypotension (IDH) has become one of the main risk factors for the prognosis of maintenance hemodialysis patients. IDH is clinically characterized by nausea, vomiting, abdominal discomfort, anxiety, headache, syncope, angina, severe shock, myocardial infarction and other threats to the patient's life. Prevention and treatment of IDH is of vital importance. This paper systematically introduces the mechanism, high risk factors, prevention and treatment of IDH. Comprehension and active intervention of IDH are essential to reduce the incidence and the adverse effects of IDH and to improve the quality of life and the survival period of the patients.
