  • Therapeutic effect of hemoperfusion for absorption of inflammatory cytokines on sepsis

    Objective To evaluate the effect of hemoperfusion for absorption of inflammatory cytokines on sepsis . Method A prospective randomized controlled study was carried out to collect 60 sepsis patients admitted to the Department of Critical Care Medicine of this hospital from June 2019 to December 2021. They were randomly divided into a study group (30 cases) and a control group (30 cases) by using the random number table method. Both groups of patients received routine treatment according to the guidelines, including fluid resuscitation, mechanical ventilation, antibiotic and vasoactive agents. For the patients with renal failure, renal replacement therapy (RRT) was used. Routine vital sign monitoring and serum procalcitonin (PCT) and interleukin-6 (IL-6) determination were recorded. The study group received two times of hemoperfusion to absorb inflammatory cytokines at 0 h and 24 h after enrollment. At 24 h and 48 h after treatment, the vital signs and related physical and chemical indexes of patients were recorded again, including norepinephrine dose, oxygenation index, PCT, IL-6 and blood lactic acid. The changes of physical and chemical indexes and the 28-day survival rate of the two groups were compared. Results There was no difference in the general situation of the two groups when they were enrolled (P>0.05). The dosage of norepinephrine [(0.77±0.48)μg·kg–1·min–1 vs. (0.92±0.62) μg·kg–1·min–1, P=0.030] and the level of blood lactic acid [(2.70±1.43)mmol/L vs. (4.05±2.60)mmol/L, P=0.001] in the study group were significantly lower than those in the control group 24 h and 48 h after treatment. The oxygenation index in the study group was higher than that of the control group 24 h after treatment (212±68)mm Hg vs. (197±42)mm Hg, P=0.042). The inflammation related indexes PCT [(17±24)ng/mL vs. (32±36)ng/mL, P=0.013] and IL-6 [299 (102, 853)pg/mL vs. 937 (247, 2230)pg/mL, P=0.026] in the study group were significantly lower than those in the control group 48 h after treatment. The dosage of noradrenaline, oxygenation index, PCT, IL-6 and blood lactate level in the study group after treatment were improved compared with those before treatment (P<0.05), while those in the control group were not significantly improved after treatment (P>0.05), and oxygenation index in the two groups had no significant difference before and after treatment (P>0.05). There was no significant difference in the 28-day survival rate between the two groups (χ2=0.211, P=0.646). Conclusion Although the hemoperfusion for absorption of inflammatory cytokine factors can not reduce the 28-day mortality of sepsis, it can significantly improve the early physical and chemical indicators of patients, and provide opportunities for follow-up treatment.
