Effect of continuous low effective dialysis combined with hemoperfusion on inflammatory stress, hemodynamic parameters and renal function in septic patients with severe acute kidney injury

摘要

Objective:To investigate the effects of sustained low-efficiency dialysis (SLED) combined with hemoperfusion (HP) on inflammatory stress, hemodynamic parameters and renal function in septic patients with severe acute kidney injury.Methods: A total of 82 cases of sepsis with severe acute renal injury were divided into control group (n=41) and observation group (n=41) according to the random data table method. Two groups of patients were given conventional support treatment, on this basis, the control group was treated with Continuous renal replacement therapy (CRRT), and the observation group was treated with SLED plus HP. The levels of inflammatory factors, hemorheological parameters and renal function indexes of the two groups were compared before and after treatment.Results: There was no significant difference in the levels of CRP, WBC, PCT, MAP, OI, BUN and Scr between the control group and the observation group before the treatment. Compared with the level before treatment, the levels of CRP, WBC, PCT, BUN and Scr in the two groups were significantly decreased after treatment, while the levels of MAP and OI were significantly increased. Compared with the level of the control group after treatment, the levels of CRP, WBC, PCT, BUN and Scr in the observation group were significantly lower than those in the control group, the levels of MAP and OI were significantly increased, the difference was statistically significant.Conclusion:SLED combined with HP regimen in treatment of sepsis combined with severe acute kidney injury can effectively inhibit the release of inflammatory factors, improve hemodynamics and renal function, and has an important clinical value.
