CAPD Catheter Insertion
Continuous Ambulatory Peritoneal Dialysis (CAPD) catheter insertion involves placing a catheter into a patient’s peritoneal cavity to facilitate peritoneal dialysis, an alternative to hemodialysis for treating end-stage renal disease (ESRD). CAPD offers patients greater flexibility and independence, as it can be performed at home and doesn’t require machine assistance

The CAPD catheter, also known as a Tenckhoff catheter, is a soft, flexible tube surgically inserted into the peritoneal cavity through a small incision near the navel. The procedure is typically done under local anesthesia with sedation and takes about 30 to 60 minutes. The catheter allows dialysis fluid to be introduced into and drained from the peritoneal cavity, where the peritoneal membrane acts as a natural filter to remove waste products and excess fluids from the blood.
After insertion, the catheter must heal for a period before it can be used for dialysis, usually around two weeks. During this time, patients are educated on how to perform CAPD, including the proper technique for connecting and disconnecting the dialysis bags, maintaining sterile conditions to prevent infection, and monitoring their health.
CAPD involves infusing a dialysis solution into the peritoneal cavity, allowing it to dwell for several hours, and then draining it out. This process is repeated multiple times a day. CAPD provides continuous dialysis, which can lead to more stable blood chemistry and fluid balance compared to intermittent hemodialysis.
The benefits of CAPD include greater lifestyle flexibility, fewer dietary restrictions, and the ability to manage dialysis independently. However, patients must be vigilant about infection control, as the risk of peritonitis (infection of the peritoneal cavity) is a significant concern. Proper training and adherence to hygiene protocols are critical to minimize this risk.
In conclusion, CAPD catheter insertion is a key component of peritoneal dialysis, offering a viable and flexible dialysis option for patients with ESRD. The procedure is relatively simple and enables patients to perform dialysis in the comfort of their homes. With proper training and care, CAPD can significantly improve patients' quality of life and provide effective renal replacement therapy.
