ABSTRACT
Objective:To investigate the effect of bedside high-flow continuous blood purification (CBP) combined with Xuebijing in the treatment of severe sepsis (SS) and the influence on the patient′s coagulation-fibrinolysis index, immunity index and expression of peripheral blood Toll-like receptor 4 (TLR4).Methods:Ninety-three patients with SS who were admitted and treated in the Lianyungang First People′s Hospitalfrom January 2017 to October 2019 were selected. They were divided into the combined group (51 cases, treatment with bedside high-flow CBP and Xuebijing injection based on bundle therapy) and the control group (42 cases, treatment with Xuebijing injection based on bundle therapy). The changes in coagulation and fibrinolysis index, immunity index, biochemical index such as TLR4 before treatment and after 1 week of treatment were compared between the two groups. The incidences of complications in both groups were statistically analyzed, and the discharge time from ICU, mechanical ventilation time and 28-day mortality were recorded.Results:After 1 week of treatment, the levels of prothrombin time (PT) and activated partial thromboplastin time (APTT) in the two groups were shortened, D-dimer (D-D) and fibrinogen (FIB) were decreased ( P<0.05); and the levels of PT and APTT in the combined group were shorter than those in the control group, the levels of DD and FIB were lower than those in the control group, there were statistical differences ( P<0.05). After 1 week of treatment, the levels of CD 4+ and CD 4+/CD 8+ ratio in both groups were increased ( P<0.05), and the levels of CD 4+ and CD 4+/CD 8+ ratio in the combined group were higher than those in the control group ( P<0.05). After 1 week of treatment, the levels of TLR4, C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBC), blood lactate (Lac), blood urea nitrogen (BUN) and serum creatinine (Scr) in both groups were decreased ( P<0.05), meanwhile, the above indexes in the combined group were lower than those in the control group ( P<0.05). The incidence of multiple organ failure and the 28-day mortality rate in the combined group were lower than those in the control group: 3.92%(2/51) vs. 19.05%(8/42), 13.73%(7/51) vs. 30.95%(13/42), there were statistical differences ( P<0.05). The discharge time from ICU and mechanical ventilation time in the combined group were shorter than those in the control group: (12.35 ± 2.14) d vs. (14.17 ± 3.36) d, (7.12 ± 2.23) d vs. (8.51 ± 2.39) d, there were statistical differences ( P<0.05). Conclusions:Bedside high-flow CBP combined with Xuebijing injection in the treatment of SS can improve the patient′s condition, regulate the balance of coagulation and fibrinolysis, avoide the activation of coagulation, inhibite inflammatory response, reduce the expression of TLR4 in peripheral blood, improve immune function, protecte kidney function and promotethe patient′s recovery.
