Efficacy of continuous blood purification in the treatment of severe sepsis in children / 中国小儿急救医学

ABSTRACT

Objective:To evaluate the efficacy and mechanism of continuous blood purification(CBP) in the treatment of severe sepsis in children.Methods:A total of 42 patients with severe sepsis were enrolled in the study.According to the parents undefined desire to treatment, on the basis of the same treatment condition, 30 cases in the blood purification group were treated with CBP, and 12 cases in the control group were given the routine treatment without CBP treatment.The difference of each index between the two groups at the baseline(before treatment) and 72 hours after treatment were observed.Results:The differences of heart rate, mean arterial pressure and brain natriuretic peptide before and after treatment in the blood purification group were significantly higher than those in control group( P<0.05), and the differences of oxygenation index, 24-hour average urine volume, blood urea nitrogen, creatinine and Glasgow coma score in the blood purification group were significantly higher than those in control group( P<0.05). The difference of capillary refill time, lactic acid and central venous oxygen saturation in blood purification group were significantly higher than those in control group( P<0.05). The level of white blood cell count, C-reactive protein, procalcitonin and interleukin-6 in blood purification group were significantly higher than those in control group, with all significant difference( P<0.05). There was significant difference in critical illness score between two groups after treatment and before treatment.The mortality rate of the blood purification group was significantly lower than that in control group( P<0.01). Conclusion:CBP can improve cardiovascular function, brain function, renal function, tissue perfusion, inflammation index, internal environment, and improve the score of children with severe sepsis.
