An indwelling peritoneal catheter is a thin, rubber tube. One end is placed in your belly (abdomen) and the other is outside your body. It's used to drain fluid from the abdominal cavity (peritoneal cavity). It may be connected to a small bag that holds the fluid drained fluid. Or it may be connected to a suction device.

Abnormal buildup of fluid in the abdominal cavity is called ascites. This can cause pain, bloating, shortness of breath, and digestion problems. It can also cause weight gain, severe tiredness (fatigue), and swelling in the legs and ankles. Draining the fluid can ease these symptoms and help you feel better.

Ascites can be caused by:

• Cirrhosis
• Heart failure
• Kidney failure
• Some types of cancer
• Hypoalbuminemia (low albumin). Albumin keeps fluid in your blood vessels.

The indwelling abdominal catheter (IAC) is put in place with a minor surgery. Your skin is cleaned and numbed with medicine. The doctor makes a small cut (incision) in your skin. They gently put the catheter through the incision into the abdominal space. They use ultrasound or other imaging to guide this placement. One end of the tube stays outside your skin. A small piece of extra material on the tube just inside the skin helps it stay in place. This piece of extra material is called a cuff.

The catheter will drain extra fluid and ease your abdominal symptoms. It can be attached to a small bottle when it's time to drain fluid. When not being used, the catheter is coiled next to your skin and covered with a dressing. The catheter will be left in place for weeks or months. Your health care team will tell you how long it will stay in place.

• Drain fluid with the catheter system exactly as instructed by your health care team. You may need to do this every 1 to 2 days.
• You can shower if your catheter site is fully covered with a secure dressing that sticks to your skin. Make sure there are no gaps around the edge where it sticks to your skin. Follow any instructions from your health care team.
• Don't let your catheter go underwater. Do not take a bath, swim in a pool, or sit in a hot tub.
• If any part of the padding under the dressing gets wet, you will need to remove it. Change it for dry padding as instructed.

While you have an abdominal catheter, the areas affected by the catheter are at risk for infection. If you have signs of infection, you will need to take antibiotic medicine.

To help prevent infection:

• Wash your hands before you touch the dressing or catheter.
• When draining fluid, use only clean supplies set up in a clean area.
• Make sure the catheter is always clean, dry, and covered when you are not draining fluid.
• Don't go into a pool or hot tub.

Watch for signs of infection. These can include:

• Fever of 100.4ºF (38ºC) or higher, or as advised by your doctor
• Pain that gets worse
• Redness, swelling, fluid, or warmth where the catheter goes into your skin
• Changes in the way the fluid looks

Call your doctor right away if any of these happen:

• You have signs of infection (see above)
• Increase in pain
• Wound opens
• Leaking fluid (pus)
• The small cuff just inside your skin has pulled out
• The catheter has started to pull out
• Not much fluid is draining
• You are short of breath
• Your symptoms don't get better, or they get worse
• Fever
