Current practice of conventional intermittent hemodialysis for acute kidney injury

摘要

The use of conventional intermittent hemodialysis (IHD) represents a mainstay of supportive care of patients with acute kidney injury (AKI). However, a number of fundamental questions regarding the optimal management of IHD remain unanswered after more than six decades of renal replacement therapy (RRT). This review summarizes current evidence regarding the timing of initiation of intermittent hemodialysis, the comparative outcomes (mortality and recovery of renal function), the prescription of the intensity of this therapy and discontinuation of dialysis. The way conventional IHD is performed has an impact on the outcome of sick patients with AKI. The value of regular education and training of those who provide IHD cannot be emphasized enough. However, we must be realistic in our expectations that no mode of RRT per se will substantially alter the excessive mortality of critically ill-patients with AKI.Keywords: Acute kidney injury, intermittent hemodialysis, standard of care
