RESUMEN
Objective To explore the clinical efficacy of artificial liver technique - double plasma molecular adsorption(DPMAS) combined with continuous renal replacement therapy(CRRT) in the treatment of multiple organ dysfunction syndrome(MODS) patients with liver failure. Methods From April 2014 to October 2016, in the Qinghai Provincial People's Hospital emergency ICU hospitalized MODS combined with liver failure patients were enrolled in this study. On the basis of comprehensive medical treatment, these patients were randomly(random number) divided into CRRT control group(23 cases) and DPMAS + CRRT treatment group(22 cases). Blood biochemical, coagulation index, inflammatory factor and severity score of two groups were comparied before and 72 h after treatment. Results The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), blood amine(NH3), creatinine(CREA), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), heart rate(HR),APACHE Ⅱ score and SOFA score in CRRT control group were statistically different before and after treatment (P<0.01). However, there was no significant difference in the levels of total bilirubin(TBIL), direct bilirubin(DBIL), bile acid(TBA), prothrombin activity(PTA) and international standardized ratio(INR) (P> 0.05); In the DPMAS + CRRT treatment group, the levels of ALT, AST, NH3, CREA, IL-6, TNF-α, HR, APACHEⅡand SOFA scores were significantly different before and after treatment (P<0.01), as well as the levels of DBIL, TBA, PTA, INR(P<0.01). There was significant differences in ALT, AST, TBIL, DBIL, TBA PTA, INR, IL-6, TNF-α, APACHE Ⅱ and SOFA scores between the two groups (P<0.05), while the levels of CREA, NH3, MAP, HR of these two groups had no significant difference (P>0.05). Conclusions Because of the combination of double plasma adsorption, besides the advantages of CRRT, DPMAS+CRRT can remove bilirubin and bile acid which can not be removed by CRRT, also improve coagulation function. The clearance efficiency of inflammatory factors is also higher, and the severity score is reduced more significantly.
