Peritoneal Dialysis

Diálisis peritoneal

Types of peritoneal dialysis

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) names two types. Continuous ambulatory peritoneal dialysis (CAPD) doesn't use a machine: you do the exchanges during the day by hand. With automated peritoneal dialysis, a machine called a cycler fills and empties your belly three to five times during the night. NIDDK adds that people sometimes call this treatment continuous cycler-assisted peritoneal dialysis or CCPD. The time that the dialysis solution is in the belly is called the dwell time.

Possible problems named by NIDDK

NIDDK says possible problems from peritoneal dialysis include infection, hernia, and weight gain. A person can get an infection of the skin around the catheter exit site or can develop peritonitis, an infection in the fluid in the belly. Among the things NIDDK says peritonitis may cause is an unusual color or cloudiness in used dialysis solution. NIDDK states: "Seek immediate care if you have signs of infection."

What it means

Peritoneal dialysis is a treatment for kidney failure that uses the lining of your abdomen, or belly, to filter your blood inside your body. Health care providers call this lining the peritoneum. A few weeks before treatment starts, a surgeon places a soft tube, called a catheter, in the belly. Dialysis solution, which is water with salt and other additives, flows from a bag through the catheter into the belly, where it absorbs wastes and extra fluid from the body; after a few hours, the solution and the wastes are drained out. Emptying the used solution and refilling the belly with fresh solution is called an exchange. MedlinePlus describes peritoneal dialysis as one of the two main types of dialysis; the other is hemodialysis, which uses a machine.

Other Spanish termsWhere it is usedNote
DPGeneralAbbreviation that the MedlinePlus en español encyclopedia article gives in parentheses after the full name.

Diálisis peritoneal is feminine: la diálisis peritoneal. NIDDK's Spanish page defines it as a treatment for kidney failure (insuficiencia renal) that uses the lining of the abdomen to filter the blood. The MedlinePlus en español encyclopedia article abbreviates it DP. For the lining itself, NIDDK's Spanish page writes el peritoneo, while MedlinePlus en español writes membrana peritoneal.

Treatment words on NIDDK's Spanish page: the tube is un catéter; the fluid is solución de diálisis; one cycle of draining and refilling is un intercambio; and the dwell time is tiempo de permanencia o de retención. The two types are diálisis peritoneal ambulatoria continua and diálisis peritoneal automatizada, and the machine is una cicladora. Peritonitis is spelled the same in both languages. For the warning about infection, the Spanish page says the patient debe buscar atención médica inmediata if there are signs (indicios) of infection.

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
