Continuous Ambulatory Peritoneal Dialysis (CAPD) is a form of renal replacement therapy for end-stage kidney disease.
It uses the peritoneal membrane as a natural filter to remove waste and excess fluid. CAPD is performed manually several times a day and offers patients independence in their care.
A soft catheter is inserted into the abdominal cavity to deliver and drain dialysate fluid.
The solution absorbs waste and fluid from the blood through the peritoneal membrane via osmosis and diffusion.
The solution remains in the cavity for a few hours, allowing the exchange of toxins and electrolytes.
Used solution is drained out by gravity, removing waste and excess fluid.
The cycle repeats with fresh solution multiple times a day, ensuring ongoing filtration.
CAPD is essential for managing kidney failure when dialysis is needed but vascular access is limited or hemodialysis is not suitable.
CAPD helps eliminate toxins that accumulate due to kidney failure, maintaining chemical balance.
Excess fluid is removed during exchanges, preventing complications like edema or hypertension.
Helps regulate essential electrolytes like potassium, sodium, and calcium.
Allows patients to perform dialysis at home and continue their routine lives with minimal disruption.
Less stressful on the heart and body than conventional hemodialysis.
No need for arteriovenous fistula; suitable for patients with poor vascular access.
Ideal for individuals allergic to anticoagulants or unable to undergo hemodialysis.
