Acute single peritoneal dialysis is a commonly used procedure for managing acute renal failure. It can be initiated quickly and is useful for patients who are hemodynamically unstable or have limited access to other dialysis methods. The procedure involves inserting a catheter into the peritoneal cavity and exchanging dialysate fluid in cycles to remove waste and correct electrolyte imbalances. Potential complications include pain, bleeding, bowel injury, and peritonitis. Care must be taken to aseptically perform exchanges and avoid malposition of the catheter.
