RESUMO
Objective:To investigate the effect of continuous blood purification (CBP) on inflammatory factors and immune function in patients with sepsis,in order to provide reference for clinical treatment of sepsis.Methods:A total of 76 patients with severe sepsis,who were treated in ICU of Daqing Oilfield General Hospital from June 2014 to December 2016,were selected.The patients were divided into conventional group (n=36) and CBP group (n=40) according to the received treatment method.The patients in the conventional group were treated with targeted therapy and life support,while the patients in the CBP group were treated with CBP on the basis of targeted therapy.The levels of interleukin-6 (IL-6),interleukin-10 (IL-10),tumor necrosis factor-α (TNF-α) and C reactive protein (CRP) of the patients in the two groups were detected and compared before treatment and after 3d of treatment.The CD3+,CD4+,CD8+T cell and the CD4+/CD8+ ratio before treatment and after 3 d of treatment were calculated and compared between the two groups.Results:There was no significant difference in the level of serum inflammatory factors between the two groups before treatment (P＞0.05).The levels of serum inflammatory factors in the two groups were significantly decreased after 3 d of treatment,and the levels of IL-6,TNF-α and CRP in the CBP group were significantly lower than those in the conventional group (P＜0.05).There was no significant difference in immune function indexes between the conventional group and the CBP group before treatment (P＞0.05).After 3d of treatment,CD3+,CD4+ and CD4+/CD8+ ratio were significantly increased in the two groups,and the CD4+ and CD4+/CD8+ ratio of the CBP group were sig-nificantly higher than those of the conventional group (P＜0.05).Conclusion:The application of CBP in the treatment of patients with sep-sis can obviously improve the expression of inflammatory factors of patients,and can improve the immune function and promote the re-covery of immune function.
