Septic related acute kidney injury

Sepsis is the leading cause of acute kidney injury (AKI) in pediatric intensive care unit.Development of AKI during sepsis increased patient morbidity,predicts higher mortality and days of stay in the intensive care unit.The mechanisms behind AKI in sepsis remain controversial but were believed to be complex and multi-factorial.The pathophysiology of AKI in sepsis involved intrarenal hemodynamic changes,endothelial dysfunction,infiltration of inflammatory cytokines.The new markers of neutrophil gelatinase-associated lipocalin as the representative is helpful for early diagnosis of AKI.Renal replacement therapy (RRT)is the main treatment of sepsis related AKI.At present,the model,dose and exact timing of RRT is not well defined.A widely accepted viewpoint is that the injury stage of RIFLE diagnostic criteria and fluid overload up to 10％ ～ 20％ is the beginning of the most appropriate chance of RRT.
