RESUMO
Sepsis is a systemic inflammatory response that can further develop into severe sepsis (septic shock), which eventually leads to multiple organ dysfunction syndrome (MODS). This study aimed to assess the effects of continuous renal replacement therapy (CRRT) on acute renal injury caused by severe sepsis by monitoring biochemical parameters. A total of 60 patients with septic shock and acute kidney injury were included. The control group (30 cases) was treated with routine treatment and intermittent renal replacement therapy (IRRT). The experimental group (30 cases) was treated with routine treatment and continuous renal replacement therapy CRRT. The changes in inflammation and biochemical indexes and APACHE- II score were evaluated before the treatment and 1, 3, and 7days after the treatment. The inflammatory markers (neutrophil percentage, C-reactive protein (CRP) and procalcitonin (PCT) levels) in the experimental group decreased significantly after treatment. In the control group, the index of inflammation still increased one day after treatment and decreased on day 3 of treatment. After treatment, blood lactate, serum creatinine and urea nitrogen levels decreased, but the urine volume increased. After treatment, the vasoactive dose in the experimental group was significantly lower than that of the control group (P less than 0.05). CRRT is a good treatment for septic shock-related acute kidney injury, which improves biochemical indicators and protects kidney function.
