Reduction of non-enzymatic antioxidants in plasma during ECMO-treatment in ARDS by influence A H1N1
2018
Abstract Purpose In critically ill patient it is observed a severe oxidative stress, not only due to the acute pathology but also for some therapeutic treatments. The aim of the present study was to analyze the variations of non-enzymatic antioxidants in plasma during veno-venous ECMO-treatment in a homogeneous population of critical patients with ARDS. Materials and methods We carried out a retrospective study enrolling all patients with ARDS by influence A H1N1 treated with veno-venous ECMO. In all patients included, we have recorded clinical and laboratory parameters considered indicators of oxidative stress during the first week of treatment. Results With regard to non-enzymatic antioxidants evaluated, we observed that both albumin and uric acid decreased significantly, at all observation times, after ECMO-treatment [(25.88 ± 4.51, 18.05 ± 4.27, 16.32 ± 4.57, 19.07 ± 5.10, p p p = 0.03). Conclusions The veno-venous ECMO-treatment causes a significant reduction of some of the major non-enzymatic antioxidants and a possible increase in insulin resistance in patients with ARDS by influence A H1N1.
