Peritoneal Dialysis Simulator

Quick Answer: A peritoneal dialysis simulator is a training model of the abdomen, usually fitted with a PD catheter, used to teach how fluid is drained from and filled into the peritoneal cavity and how the catheter exit site is kept clean. Renal nurses use it to train staff, patients and carers before home dialysis.

How Peritoneal Dialysis Works

Peritoneal dialysis uses the patient’s own peritoneum, the thin membrane lining the abdominal cavity, as the filter. A soft catheter tunnelled through the abdominal wall carries dialysis solution into the cavity, where waste products and excess water pass from the membrane’s blood vessels into the fluid. After a dwell of several hours the used fluid is drained out and replaced. In continuous ambulatory PD (CAPD) the patient does these exchanges by hand several times a day; in automated PD a machine called a cycler does them overnight.

Because the patient or carer performs every exchange at home, training concentrates on technique and infection control. Peritonitis, an infection of the membrane, most often follows a break in technique, so learners practise hand washing, wearing a mask, connecting and disconnecting without touching sterile parts, and the drain, flush and fill sequence. They also learn to inspect the drained fluid, since cloudiness is an early warning sign, and to check the exit site for redness, crusting or discharge.

A peritoneal dialysis simulator lets all of this be rehearsed on a model abdomen rather than on a new patient’s freshly placed catheter. The listing does not state the catheter type, whether fluid can be run through the model, or which accessories come with it, so ask what is included. To revise how the kidney normally filters blood, the human kidney structures model is a useful companion.

Who Trains on a PD Simulator

• Renal nurses teaching patients and family carers before they start home dialysis
• Nursing students learning aseptic technique and exit-site dressing changes
• Dialysis unit induction for newly appointed staff
• Patient education sessions comparing peritoneal dialysis with haemodialysis

Looking After the Simulator

• Drain any water used in a demonstration out of the peritoneal dialysis simulator before storage and leave the connectors open to dry.
• Use plain water for fluid demonstrations unless the maker recommends otherwise, and label practice bags clearly as not for patient use.
• Clean the skin surface around the catheter with a mild detergent; frequent alcohol wipes can dry and crack some simulated skins.
• Replace worn tape and dressings after each class so the next group practises on a clean exit site.

Why Choose LabEquip

Hospital renal units and nursing colleges buy a PD simulator because exchange technique has to be secure before a patient goes home. LabEquip lists this model in its biology lab products; for questions about the catheter and accessories, use the LabEquip contact page.

Frequently Asked Questions

What is the difference between CAPD and APD?

In continuous ambulatory peritoneal dialysis the patient changes the fluid by hand, typically several times a day. In automated peritoneal dialysis a cycler machine performs the exchanges at night while the patient sleeps. Both use the same catheter and the same infection-control principles.

Why is aseptic technique stressed so much in PD training?

The catheter gives a direct path into the abdominal cavity. Touch contamination of a connector can introduce bacteria and cause peritonitis, which is painful, can damage the membrane and may end a patient’s ability to use PD.

What does cloudy drained fluid mean?

Used dialysis fluid should be clear. Cloudy fluid, often with abdominal pain or fever, is a classic sign of peritonitis, and patients are taught to keep the bag and contact their dialysis unit at once.

Why is the drain done before the fill?

Draining removes the used fluid that has taken up waste. A short flush of fresh solution into the drain bag then clears air and any contamination from the line before new fluid enters the abdomen.

How is the catheter exit site cared for?

The site is cleaned regularly with the solution the unit prescribes, dried, and covered or left open according to local practice. Patients check it for redness, swelling, pain or discharge, and anchor the catheter so it is not pulled.

Can patients practise on the simulator themselves?

Yes. Training on a model lets patients and carers repeat the steps until they are confident, while the nurse watches for breaks in technique, before they perform exchanges on the real catheter.
