Abstract: 【Abstract】 Objectives To compare the incidence of hypotension in high risk patients treated with room temperature, low temperature, and low temperature with sodium adjustable hemodialysis. Methods Twenty hemodialysis patients with high risk conditions, such as end-stage kidney diseases complicated with old age, diabetic nephrosis and heart failure, were randomly treated with conventional dialysis of normal temperature (group A), conventional dialysis of low temperature (group B) or low temperature with sodium adjustable dialysis (group C). Every patient was sequentially treated with the 3 kinds of dialysis, 10 times for each method. The incidence of hypotension and its symptoms during hemodialysis was compared. Results The incidence of blood hypotension was 20.5%, 15.5% and 7% in group A, B and C, respectively, and the incidence in group A and C is statistically different (P<0.01). Conclusion The method of low temperature with sodium adjustable hemodialysis is effective to prevent hypotension during hemodialysis, and thus improves the tolerance to hemodialysis in high risk patients.

Key words: Low temperature hemodialysis, Low temperature adjustable -sodium hemodialysis.
