Introduction to Peritoneal Dialysis
Peritoneal Dialysis (PD) is a treatment for patients with kidney failure that uses the lining of your abdomen, or belly, to filter your blood inside your body. This is different from haemodialysis, which filters your blood outside your body using a machine. PD can be carried out at home, at work or even while travelling, making it a flexible option for many people.
How Does Peritoneal Dialysis Work?
Peritoneal Dialysis works by using a dialysis solution, also known as dialysate, to clean your blood. The dialysis solution is a sterile, glucose-based fluid that is introduced into the peritoneal cavity – the space within the abdomen that houses the intestines and other organs. The peritoneal membrane acts as a natural filter, allowing waste products and excess fluids to pass from the blood into the dialysis solution. After a set dwell time, the used solution is drained and replaced with fresh dialysate.
Types of Peritoneal Dialysis
There are two main types of Peritoneal Dialysis:
- Continuous Ambulatory Peritoneal Dialysis (CAPD): This is done manually using gravity to introduce and drain the dialysis solution. It usually requires four to five daily exchanges, but it can be performed anywhere.
- Automated Peritoneal Dialysis (APD): This uses a machine called a cycler to perform multiple exchanges, typically while you sleep. APD is often preferred due to its convenience and reduced daytime disruptions.
Benefits of Peritoneal Dialysis
Peritoneal Dialysis offers several advantages, including greater flexibility and independence compared to haemodialysis. Many patients report a better quality of life as it allows them to maintain a normal daily routine. PD can also offer more stable blood chemistry and fluid levels since it's done more continuously.
Considerations and Risks
While PD is an effective treatment for many people, it may not be suitable for everyone. Some potential risks include infections such as peritonitis, hernias, and the efficiency of the dialysis may decrease over time. It's important to undergo regular medical reviews and follow your healthcare provider's advice closely.
Support and Resources in the UK
In the UK, the NHS provides comprehensive support for patients undergoing Peritoneal Dialysis. You will be supported by a multi-disciplinary team including nephrologists, nurses, and dietitians. Additionally, organisations such as Kidney Care UK and the National Kidney Federation offer valuable resources and community support.
What is Peritoneal Dialysis?
Peritoneal Dialysis, or PD, is a way to help people whose kidneys do not work well. It uses the inside of your belly to clean your blood. This is different from another method, called haemodialysis, which uses a machine outside the body. You can do PD at home, at work, or even on holiday. It is a flexible treatment.
How Does Peritoneal Dialysis Work?
PD works using a special liquid called dialysis solution, or dialysate, to clean your blood. This liquid goes inside your belly, which acts like a filter. Waste and extra water from your blood move into the liquid. After a while, you drain out the old liquid and put in new liquid.
Types of Peritoneal Dialysis
There are two main types:
- Continuous Ambulatory Peritoneal Dialysis (CAPD): You do this by hand, using gravity to move the liquid. You do it four to five times a day, but you can do it anywhere.
- Automated Peritoneal Dialysis (APD): This uses a machine called a cycler. It does the work while you sleep, which makes it easier to do during the day.
Benefits of Peritoneal Dialysis
PD helps people have more freedom compared to haemodialysis. Many people say it helps them keep doing their usual activities. It also helps keep your blood and water levels more balanced, as you do it more often.
Things to Remember and Risks
PD works well for many people, but not everyone. Some problems can happen, like infections or hernias. The dialysis might not work as well over time. You should have check-ups with your doctor and follow their advice.
Help and Support in the UK
In the UK, the NHS gives support to people on PD. You will have a healthcare team, including doctors and nurses, to help you. Groups like Kidney Care UK and the National Kidney Federation also provide help and information.
Frequently Asked Questions
Peritoneal Dialysis (PD) is a treatment for kidney failure that uses the lining of your abdominal cavity, the peritoneum, to filter waste and excess fluid from the blood.
PD involves filling the abdominal cavity with a dialysis solution through a catheter. The solution absorbs waste and excess fluids through the peritoneum and is then drained away.
There are two main types: Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD). CAPD is done manually throughout the day, while APD uses a machine to perform exchanges at night.
The frequency depends on the type of PD. CAPD usually requires 4-5 exchanges per day, while APD typically runs overnight, taking around 8-10 hours.
Yes, one of the benefits of PD is that it can be performed at home, providing more flexibility and independence compared to in-centre haemodialysis.
You will need a catheter, dialysis solution, and sterile supplies for connecting and disconnecting the dialysis solution. For APD, a cycler machine is also required.
Some potential risks include infection (peritonitis), hernias, and catheter-related complications. It’s important to follow strict hygiene protocols to minimise these risks.
Maintain a strict hygiene regimen, including washing your hands thoroughly before touching the catheter and keeping the exit site clean and dry.
Yes, you can travel while on PD. Make arrangements in advance to have supplies shipped to your destination and ensure you have a clean and safe environment to perform exchanges.
Dietary changes may include controlling fluid intake, limiting potassium, phosphorus, and sodium, and ensuring adequate protein intake. A dietitian can provide personalised advice.
Yes, regular exercise is encouraged to maintain overall health, but it’s advisable to avoid activities that put excessive strain on the abdomen. Consult your healthcare provider for specific recommendations.
PD allows for more flexibility in your schedule compared to in-centre dialysis. You can perform exchanges around your daily activities and usually don't need to visit a dialysis centre regularly.
You should not feel pain during the procedure. However, if you experience discomfort or pain, it is important to contact your healthcare provider immediately.
Store supplies in a clean, dry, and cool place. Make sure that the area is free from pests and contaminants to prevent infections.
Many patients have successfully managed their kidney failure with PD for years. Regular follow-ups with your healthcare team are essential to monitor your health and make any necessary adjustments.
Peritoneal Dialysis (PD) is a way to help when kidneys don't work. It uses the inside of your belly, called the peritoneum, to clean waste and extra water from your blood.
PD is a way to clean the blood. A tube puts a special liquid into the belly. This liquid takes away dirt and extra water. Then the dirty liquid comes out through the tube.
There are two main types of dialysis:
1. Continuous Ambulatory Peritoneal Dialysis (CAPD):
- You do this by hand.
- You do it during the day.
2. Automated Peritoneal Dialysis (APD):
- A machine helps you.
- It works at night while you sleep.
If you need help, you can:
- Ask a friend or family member to read with you.
- Use a dictionary to understand hard words.
- Ask a doctor or nurse to explain.
How often you do it depends on the type of PD. For CAPD, you usually need to swap the fluid 4-5 times each day. For APD, the machine works while you sleep, and it takes about 8-10 hours.
Yes, you can do PD at home. This gives you more freedom than going to a centre for haemodialysis.
If you find the words tricky, you can use a helper tool like a dictionary or ask someone to explain. You could also use text-to-speech tools to hear the words read aloud.
You will need a tube called a catheter. You will also need special liquid for cleaning your blood. You need clean supplies to connect and take away the liquid. For APD, you need a machine called a cycler.
There are some things to watch out for. You might get an infection, which is a sickness that can happen inside your tummy. This is called "peritonitis." You could also get a hernia, which is a lump in your tummy, or have problems with the tube used for your treatment. To stay safe, make sure to keep everything very clean and follow the rules for hygiene.
If you're finding it hard to remember the steps for staying clean, you can use reminder notes or ask someone you trust to help you. There are also apps or checklists that can be useful to make sure you’re doing everything right.
Keep everything very clean. Wash your hands carefully before you touch the catheter. Make sure the place where the catheter comes out of your body is clean and dry.
Yes, you can travel while on PD. Plan ahead to get your supplies sent to where you are going. Make sure you have a clean and safe place to do your treatment.
Changing what you eat can help. You might need to drink less water, eat less salt, and eat less of some things like bananas and potatoes. It is important to eat enough protein, like meat, eggs, or beans. A food expert, called a dietitian, can help you know what to eat.
Exercise is good for keeping healthy. But don't do activities that are hard on your tummy. Ask your doctor what exercises are safe for you.
PD can give you more freedom with your schedule. You can do your treatments at home, which means you can fit them around your daily activities. You usually don’t have to go to a dialysis centre all the time.
