Effects of hemoperfusion and hemofiltration combination on treating patients with acute organophosphours pesticide poisoning and influence of it on cholinesterase, dopamine and inflammatory factors

摘要

Objective:To investigate effects of hemoperfusion and hemofiltration combination on treating patients with acute organophosphours pesticide poisoning (AOPP) and influence of it on cholinesterase, dopamine and inflammatory factors.Methods:A total of 82 cases of AOPP patients treated in our hospital from Sep 2012 to Jul 2016 were selected as subjects. They were randomly divided to be the observation group and the control group, 41 cases for each. For patients in observation group, combined therapy of hemoperfusion (HP) and hemofiltration (HF) were provided. For patients in control group, combined therapy of HP and hemodialysis (HD) were provided. Effects on the two groups of patients were compared. Meanwhile, cholinesterase, dopamine and inflammatory factors levels in different times before and after treatment were compared.Results:Consciousness improvement times and hospitalization times in observation group were significantly lower than in control group. No significant difference showed on fatality rates between the two groups. Before treatment, no significant difference showed on CHE and DE levels between two groups of patients; 6 h and 12 h after treatment, CHE average levels in two groups were significantly higher than before treatment in the same group, and levels in observation group at the same phase were significantly higher than in control group; 6 h and 12 h after treatment, DA levels in observation group were significantly lower than the same group before treatment, and significantly lower than control group, while 12 h after treatment, DA levels in control group were significantly lower than the same group before treatment. Before treatment, no significant difference showed on serum TGF-β1, TNF-α, IL-6, IL-8 between two groups of patients. After treatment, each index levels in two groups were significantly lower than the same group before treatment, and levels in observation group at the same phase were significantly lower than control group. Conclusion:Effects of blood purification therapy on treating AOPP were worth approving, but effects of HP and HF combined therapy were more significant. In addition, improvement of HP+HF on CHE, DA and inflammatory factors were better than HP+HD.
