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.
CAPD is the original home peritoneal dialysis modality. The patient performs 4-5 exchanges per day: draining used dialysate from the abdomen, instilling fresh solution, and allowing a 4-6 hour dwell. Modern double-bag (Y-set) systems made CAPD safe with peritonitis rates below 0.4 episodes/patient-year (ISPD 2022 target). CAPD requires no cycler or electricity — only clean technique and storage space for supplies. Weekly Kt/V adequacy target is ≥1.7 per KDOQI. CAPD is particularly suited to patients with residual kidney function, flexible schedules, and those in regions with unreliable power supply.
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 medical procedure that filters waste products, excess fluids, and toxins from the blood using a dialysis machine when the kidneys can no longer perform this function adequately.
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.
