Abstract

Background: The purpose of this study was to evaluate the efficacy, complications, and mortality rate associated with acute peritoneal dialysis (PD) in patients with acute kidney injury (AKI).

Methods: A total of 75 patients who were treated at Samsung Changwon Hospital between February 2005 and March 2016 were included in the study sample. The outcomes included in-hospital survival, renal recovery, metabolic and fluid control rates, and technical success rates.

Results: Refractory heart failure was the most frequent cause of acute PD (49.3%), followed by hepatic failure (20.0%), septic shock (14.7%), acute pancreatitis (9.3%), and unknown causes (6.7%). The hospital survival of patients in the acute PD was 48.0%. Etiologies of acute kidney injury (AKI) (refractory heart failure, acute pancreatitis compared with hepatic failure, septic shock or miscellaneous causes), use of inotropes, use of a ventilator, and simplified acute physiology score (SAPS) II were associated with survival differences. Maintenance dialysis required after survival was high (80.1% [29/36]) due to AKI etiologies (heart or hepatic failures). Metabolic and fluid control rates were 77.3%. The technical success rate for acute PD was 93.3%.

Conclusion: Acute PD remains a suitable treatment modality for patients with AKI in the era of continuous renal replacement therapy (CRRT). Nearly all patients who require dialysis can be dialyzed with acute PD without mechanical difficulties. This is particularly true in patients with refractory heart failure and acute pancreatitis who had a weak requirement for inotropes.

Keywords: Peritoneal dialysis; acute kidney injury; survival; technique success.
