Description –

Continuous ambulatory peritoneal dialysis (often just called ‘the bags’) is one sort of peritoneal dialysis. It cleans your body, helps to regulate the water and replaces the work of the diseased kidneys.

CAPD is the most portable type of dialysis. It uses manual bags containing peritoneal dialysis fluid. It is done a day , via your greater peritoneal sac , with bag changes fourfold each day . It can usually be learnt in about a week and does not require needles. The lady below is connected for her bag change.

What is ”peritoneal cavity”?

The peritoneal cavity is the place in your lower abdomen (tummy), around your belly button, where you’ll put within the dialysis fluid to try to do your PD.

The peritoneal cavity features a lining called the peritoneum. There is one layer at the front under your skin and one on the within around your organs. Usually a little amount of fluid sits in your peritoneal cavity , allowing you to maneuver easily. The peritoneum usually protects your insides, especially the bowel and therefore the bladder and the female reproductive organs.

It is this space inside the peritoneal cavity where the peritoneal dialysis fluid goes. It can easily fit large amounts of fluid. To get the fluid in you require a catheter.

What is ”peritoneal catheter”?

The catheter, also called the tube or Tenckhoff, may be a soft tube about the thickness of a pencil and 30 to 40 centimetres long.

During an easy operation the catheter is placed into the peritoneal cavity , with about 10 to 15 centimetres being kept outside of the body.

The a part of the tube within the peritoneal cavity has many tiny holes to permit the dialysis fluid to travel in and out. The part under the skin features a cuff, a touch like Velcro, to keep it in place.

The part outside the body features a special connector on the top , to which a brief extension tube is then attached. The special peritoneal dialysis fluid bags are often attached to the extension tube when dialysis is required . The extension tube are often changed easily at the dialysis unit every six months.

What are “PD fluid bags”?

PD fluid is that the fluid that’s put into the peritoneal dialysis cavity through the catheter.

It’s a pure fluid and is formed to draw in water and waste from your blood, through the peritoneum. Each PD bag has about two litres of fluid in it.

The amount of PD fluid fits easily into the greater peritoneal sac in your abdomen, but may slightly increase your waistline size. initially the fluid may feel unusual but most of the people get accustomed to it very quickly.

What is “PD bag change” or “PD cycle”?

Here’s an explanation of how the PD process cleans the blood, using osmosis and diffusion.

Osmosis is when the water moves across a membrane (the peritoneal membrane) from a place where there’s excess water (blood) to a place with less water concentration (dialysis fluid).

The dialysis fluid is concentrated because it’s tons of glucose in it, which attracts the water. Different bags have different levels of glucose. The water removal are often changed by altering the bags .

Diffusion is when electrolytes (waste products) move across a membrane (the peritoneal membrane) from a place of high concentration (blood) to a place of low concentration (dialysis fluid).

Urea, creatinine, potassium and phosphate are among the electrolytes that travel from the blood to the dialysis fluid. Bicarbonate is an electrolyte that travels from the dialysis fluid into the blood where it’s needed.
