急性腎損傷之腎臟替代療法

Renal replacement therapy (RRT) is crucial in severe acute kidney injury (AKI) when conservative treatment cannot control the disease. RRT is viewed as a renal support that may let other failed organs have time to restore function. RRT should be initiated prior to obvious uremic symptoms and when patient is expected to deteriorate, not strictly in accordance with traditional indications of dialysis of renal failure. Intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) seems to have similar survival rate in patients with AKI, but CRRT should be considered as priority when patients having hemodynamic instability, acute liver failure or acute brain injury.
