Brief Summary

In septic shock, dysregulated host responses to pathogens lead to cytokine storms that damage host tissues and organs, further contributing to the development of organ dysfunction and increased mortality. For sepsis, blood purification can remove inflammatory factors in sepsis by filtration or adsorption, so as to achieve the purpose of reducing inflammatory mediators in the body. However, there are few prospective randomized controlled studies in children. Therefore, this study intends to compare the efficacy and prognosis of different blood purifications on children with sepsis through randomized controlled studies, so as to provide a corresponding basis for the treatment of children with sepsis blood purification.

Detailed Description

Sepsis is a life-threatening organ dysfunction resulting from a dysregulated host response to infection. In septic shock, dysregulated host responses to pathogens lead to cytokine storms that damage host tissues and organs, further contributing to the development of organ dysfunction and increased mortality.

Blood purification therapy is gradually developed on the basis of renal replacement therapy, and now it is more and more widely used in the field of critical care in children. The main mechanisms are divided into dispersion, convection and adsorption. For sepsis, in addition to using the convection mechanism to remove the inflammatory mediators in the middle molecules, there are many adsorption membranes or adsorption columns used to adsorb the inflammatory factors in sepsis, so as to achieve the purpose of reducing the inflammatory mediators in the body. CVVH, HP and TPE can reduce the level of inflammation in the body in different ways, but the results of reducing inflammatory factors are different, and the outcomes of patients are also different.

Blood purification treatment can reduce inflammatory mediators in sepsis, but there are few prospective randomized controlled studies in children. Therefore, this study intends to compare the efficacy and prognosis of different blood purification in children with sepsis through a randomized controlled study. Provide the corresponding basis for blood purification treatment of the disease.

Primary Outcome Measures

Name	Time	Method
cytokine change	from enrollment to the 3th days	This is a binary variable. It is also a compositional variable including IL-6, IL-10, TNF-a, IL-4, IL-2 and etc. If one of the factors changes, it is considered that the variable changes. If the cytokine drops below half of the original value, it is considered to be changed. The cytokine would be measured measured at the 7th day after enrollment
organ injury changes	from enrollment to the 3th days	the difference of the organ injury changes would be measured at the 3th day after enrollment

Secondary Outcome Measures

Name	Time	Method
survival rate	from enrollment to the 28th days	the survival rate would be measured at the 28th day after enrollment
