Abstract
This study is to evaluate the efficacy of erythropoietin in treating sepsis-associated acute respiratory distress syndrome (ARDS). One hundred patients with sepsis-related ARDS were randomized into the placebo group and Erythropoietin (EPO) group. Patients in the placebo group received saline as placebo on the standard therapy, while the EPO group received recombinant human erythropoietin injections on the standard therapy. It was found that the heart rate and mean arterial pressure did not differ significantly between days 7 and 14 after treatment initiation (p > 0.05). The partial pressure of oxygen (PaO2) and oxygenation index levels measured on days 7 and 14 were significantly higher than the placebo group and partial pressure of carbon dioxide (PaCO2) was significantly lower than the placebo group (p < 0.05). Lung capacity and functional residual capacity (and FRC) increased significantly in tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and C-reactive protein (CRP) concentrations (p < 0.05). In the EPO group, the duration of mechanical ventilation was significantly shorter and the mortality rate was significantly reduced (Log-Rank test, χ2 = 4.651, p = 0.031). The results confirm that EPO significantly improves lung function and blood gas parameters, reduces serum levels of inflammatory markers, and reduces the risk of death in sepsis-induced ARDS patients, highlighting the potential therapeutic role of EPO in the management of this disease.
