The sterile dialysate fluid instilled into the abdomen during peritoneal dialysis — dextrose-based, drawing waste and fluid across the peritoneal membrane.
PD solution (dialysate) is a sterile fluid containing dextrose (the osmotic agent), electrolytes, and buffer that is instilled into the peritoneal cavity and drained after a dwell. The dextrose concentration (1.5%, 2.5%, 4.25%) controls the osmotic pull of fluid — higher dextrose draws more ultrafiltration but is harder on the membrane and raises glucose absorption. Solution types vary by buffer (lactate, bicarbonate), additives (icodextrin for long dwells), and connection system (twin-bag). Peritonitis prevention and correct technique are tied to how the solution connects and drains.
A dialysis modality that uses the patient's peritoneal membrane as a natural filter, with dialysate fluid introduced into the abdominal cavity to remove waste and excess fluid.
A peritoneal dialysis modality requiring 4-5 manual exchanges of dialysate daily, each involving a 20-30 minute drain and refill, performed by the patient at home.
Inflammation of the peritoneal membrane caused by infection during peritoneal dialysis, the most common serious complication requiring prompt diagnosis and antibiotic treatment.
The specially formulated solution used in dialysis that draws waste products and excess electrolytes from the blood across the dialyzer membrane.
