Abstract: 【Abstract】Acute kidney injury (AKI) is one of the most common critical illnesses. Renal replacement therapy is an important measure for the treatment of AKI patients. The application of peritoneal dialysis (PD) in AKI is often overlooked. PD has the advantages of easy operation, no need for special equipment
and anticoagulation, and little influence on hemodynamics. It has been recommended by the International Society of Peritoneal Dialysis (ISPD) as one of the ideal renal replacement methods for AKI treatment. This article reviews the current status, advantages, appropriate time for emergency dialysis, access and dialysate, dialysis dose and complications of PD in adult AKI.

Key words: peritoneal dialysis, acute kidney injury, dialysis timing, dialysis dose
