Abstract: 【Abstract】 Objective To study the diagonal reinforcement ultrafiltration mode on maintenance hemodialysis patients cardiac function and the influence of blood pressure rhythm. Methods 100 cases of hemodialysis patients for support in accordance with the principle of randomized divided into observation
group and control group, each group of 50 cases, including the observation group take diagonal reinforcement ultrafiltration mode, the control group take the conventional linear ultrafiltration mode, each for hemodialysis 2000 cases of times, observation two groups of patients dialysis process center rate, blood pressure and low blood pressure rhythm changes occur. Results two groups of patients dialysis process center rate, blood pressure comparison were no statistical difference (P＞0.05); The observation group occur hypotension 41 cases of time (2.05%), and 278 cases of control group occur hypotension times (13.90%), two groups of comparisons significant difference (χ2=22.321,P=0.000). Conclusion the application of diagonal reinforcement ultrafiltration model for blood dialysis, there was no significant effect on heart function of patients, but can significantly reduce the incidence of hypotension dialysis process.
