Chronic Ambulatory Peritoneal Dialysis

Published with the inputs from Dr Midhun Ramesh, Senior Consultant, Nephrology, Baby Memorial Hospitals- Kannur

Chronic Ambulatory Peritoneal Dialysis (CAPD) is a home-based dialysis treatment for patients with chronic kidney disease (CKD) or end-stage kidney disease (ESKD). Instead of using a machine, CAPD uses the patient’s peritoneum (the inner lining of the abdomen) as a natural filter to remove waste products and excess fluid from the body.

It allows patients to manage their dialysis independently at home, giving them flexibility and a better quality of life while maintaining effective kidney function replacement.

What is chronic ambulatory peritoneal dialysis (CAPD)?

CAPD is a continuous form of dialysis performed manually, usually four times a day, using a sterile dialysis fluid that is introduced into the abdominal cavity through a soft catheter.

The fluid absorbs waste and toxins from the blood through the peritoneal membrane, after which it is drained and replaced with fresh solution. This gentle, continuous process mimics natural kidney function.

When is CAPD recommended?

CAPD is recommended for patients with:

• Chronic or end-stage kidney disease (CKD/ESKD)
• Difficulty accessing vascular sites for hemodialysis
• Heart disease or low blood pressure, making hemodialysis unsuitable
• Desire for home-based therapy to maintain independence
• Living far from a dialysis center or needing flexible scheduling

Your nephrologist at BMH will determine if you are medically and socially suitable for CAPD after evaluating your overall health and lifestyle.

How is CAPD performed?

• A soft catheter is surgically placed into the abdominal cavity.
• Dialysis solution is infused into the abdomen through the catheter.
• The fluid stays in the abdomen for 4–6 hours (dwell time), during which it absorbs waste and excess fluid.
• The used fluid is then drained and replaced with a new one — this process is called an exchange.
• Typically, 4 exchanges per day are done manually, each taking about 30–40 minutes.

Patients are trained by specialized dialysis nurses at BMH to perform CAPD safely at home, maintaining hygiene and proper technique.

Is CAPD safe?

Yes. CAPD is safe and effective when performed with proper hygiene and technique. Most patients manage it independently after a short training period. Possible but manageable complications include:

• Peritonitis (infection of the abdominal lining)
• Catheter site infection
• Fluid imbalance or leakage

These risks are minimized with regular follow-up, good hygiene, and support from the dialysis care team.

What are the benefits of CAPD?

• Home-based and independent treatment
• No need for a dialysis machine or hospital visits
• Gentle and continuous toxin removal, similar to natural kidney function
• Stable blood pressure and fewer heart complications
• Flexible daily routine and dietary freedom
• Better quality of life and travel convenience

How is CAPD different from hemodialysis?

CAPD offers greater independence and is particularly suitable for patients who wish to avoid frequent hospital visits.

Who performs CAPD training and monitoring?

At Baby Memorial Hospital (BMH), CAPD is managed by a dedicated team of nephrologists, dialysis nurses, and dietitians, who:

• Train patients and caregivers on sterile exchange techniques
• Monitor monthly lab results and fluid balance
• Provide dietary and lifestyle guidance
• Offer round-the-clock assistance for troubleshooting or emergencies

What is recovery and long-term care like for CAPD patients?

• Hospital stay: 1–2 days for catheter placement and training
• Learning period: 1 week of guided sessions at BMH
• Follow-up: Regular clinic visits every 4–6 weeks
• Lifestyle: Normal daily activities and travel possible with planning

With discipline and proper support, patients on CAPD lead active, productive lives.
