Abstract:

Acute kidney injury (AKI) is a common syndrome,and the  most frequent two aetiologies are sepsis and hypovolemia.AKI can lead to fluid overload,electrolyte acidbase disturbance and other dysfunction.For AKI patients or patients with high risk of AKI,it is important to maintain effective circulatory volume and prevent fluid overload.In this paper,the objectives and indications of fluid therapy,fluid resuscitation during AKI,and fluid management strategies for continuous renal replacement therapy  are reviewed.
