Peritoneal Dialysis

Introduction: What is Peritoneal Dialysis?

Peritoneal dialysis (PD) is a life-saving kidney treatment that helps people with kidney failure clean their blood and remove extra fluids from their bodies. Unlike traditional hemodialysis which uses a machine outside your body, peritoneal dialysis uses the lining of your belly (called the peritoneum) to filter your blood. This guide will walk you through everything you need to know about peritoneal dialysis. Our goal is to help you feel more comfortable and confident about this treatment option.

Understanding Peritoneal Dialysis

In peritoneal dialysis, we use the lining of your belly (called the peritoneum) as a natural filter. This lining acts like an artificial kidney, cleaning your blood right inside your body. It’s different from hemodialysis, which cleans your blood outside your body using a machine.

Many people choose peritoneal dialysis because it gives them more freedom in their daily lives. You can do it at home, at work, or even while traveling. It’s a gentler treatment that happens all the time, instead of just a few times a week like hemodialysis.

How Peritoneal Dialysis Works?

Peritoneal dialysis uses a special fluid called dialysate to clean your blood. Here’s how it works:

A soft tube called a catheter is placed in your belly through a small surgery.
The dialysate fluid goes into your belly through this tube.
The fluid stays in your belly for a few hours. During this time, it pulls waste and extra water from your blood.
After a few hours, you drain the fluid out. It now contains the waste from your blood.
You put in fresh dialysate, and the process starts again.

This process of filling and draining is called an exchange. You’ll do several exchanges each day to keep your blood clean.

Types of Peritoneal Dialysis

There are two main types of peritoneal dialysis:

Continuous Ambulatory Peritoneal Dialysis (CAPD)

You do this type of dialysis without a machine.
You change the fluid in your belly 3-5 times during the day.
Each exchange takes about 30-40 minutes.
You can do your exchanges at home, at work, or while traveling.

Automated Peritoneal Dialysis (APD)

A machine (called a cycler) does the exchanges for you.
It usually happens while you sleep at night.
The machine fills and drains your belly several times overnight.
Some people might need an extra exchange during the day.

Both types of peritoneal dialysis give you more freedom compared to traditional hemodialysis. You can do your treatments at home, which means fewer hospital visits and more time for your daily activities

Who Needs Peritoneal Dialysis?

Peritoneal dialysis is for people with end-stage kidney disease. This means your kidneys have stopped working well enough to keep you healthy. You might need dialysis if:

Your kidneys are working at less than 10-15% of their normal function.
You have severe symptoms of kidney failure that can’t be controlled with medication alone.
You want a dialysis option that gives you more flexibility in your daily life.
You’re waiting for a kidney transplant and need dialysis in the meantime.

Peritoneal dialysis might be a good choice if you:

Want to do your treatments at home
Like to travel or have an active lifestyle
Don’t want to visit a dialysis center several times a week
Have some leftover kidney function you want to preserve longer

Why is Peritoneal Dialysis Performed?

Peritoneal dialysis is performed when your kidneys can no longer do their job effectively. Healthy kidneys have several important functions:

Cleaning your blood: They remove waste products and extra fluid from your body.
Balancing chemicals: They keep important minerals like sodium and potassium at the right levels in your blood.
Controlling blood pressure: They help regulate your blood pressure.
Supporting bone health: They activate vitamin D, which is important for strong bones.
Stimulating red blood cell production: They make a hormone that tells your body to produce red blood cells.

When your kidneys fail, they can’t perform these vital functions. This can lead to a build-up of waste products and fluid in your body, which can be dangerous if left untreated. Peritoneal dialysis steps in to do some of the work your kidneys can’t do anymore.

Here are some benefits of addressing kidney failure with peritoneal dialysis:

Better quality of life: By removing waste and extra fluid from your body, you’ll likely feel better and have more energy.
Fewer dietary restrictions: Compared to hemodialysis, peritoneal dialysis often allows for a more flexible diet.
More control: You can do your treatments at home on your schedule.
Preserves remaining kidney function: Some studies suggest that peritoneal dialysis might help preserve any remaining kidney function longer than hemodialysis.

By starting peritoneal dialysis when your doctor recommends it, you’re taking an important step to stay as healthy as possible despite kidney failure.

Who Might Not Be Suitable for Peritoneal Dialysis?

Some people might not be able to do peritoneal dialysis if they:

Have had many abdominal surgeries.
Have a large hernia in their belly.
Can’t do the procedure themselves and don’t have help at home.
Have certain bowel diseases.

Alternatives to Peritoneal Dialysis

If peritoneal dialysis isn’t suitable for you, there are other options:

Hemodialysis: This cleans your blood using a machine outside your body. It’s usually done at a dialysis center, but home hemodialysis is also possible.
Kidney Transplant: This is when you receive a healthy kidney from a donor. It’s often the best long-term solution for kidney failure.
Conservative Management: For some people, especially those who are very ill or elderly, managing symptoms without dialysis might be the best choice.

Each option has its pros and cons. Your healthcare team will help you choose the best treatment for your situation.

What to Expect with Peritoneal Dialysis?

Before the Procedure

Before you start peritoneal dialysis, there are several steps to prepare:

Medical Evaluation: Your doctor will do a full check-up to make sure you’re ready for peritoneal dialysis.
Catheter Placement: You’ll have a small surgery to place the peritoneal dialysis catheter in your belly. This is usually done a few weeks before you start dialysis.
Training: You and your caregiver will learn how to do peritoneal dialysis. This training usually takes 1-2 weeks.
Home Preparation: You’ll need to set up a clean area at home for doing your exchanges.
Diet Changes: Your dietitian will teach you about the right foods to eat on peritoneal dialysis.
Medication Review: Your doctor might change some of your medicines to work better with peritoneal dialysis.

During the Procedure

Here’s what happens during a typical peritoneal dialysis exchange:

Wash Hands: Always start by washing your hands thoroughly to prevent infection.
Drain the Old Fluid: If there’s fluid in your belly from a previous exchange, you’ll drain it out first.
Fill with New Fluid: Fresh dialysate fluid goes into your belly through the catheter.
Dwell Time: The fluid stays in your belly for several hours. This is when it cleans your blood.
Drain Again: After the dwell time, you drain the fluid out. It now contains waste from your blood.
Repeat: You’ll do this process several times a day or night, depending on your type of peritoneal dialysis.

Each exchange usually takes about 30-40 minutes. If you use a machine for automated peritoneal dialysis, it will do the exchanges for you while you sleep.

After Starting Peritoneal Dialysis

Once you start peritoneal dialysis:

Regular Check-ups: You’ll see your doctor regularly to make sure the treatment is working well.
Blood Tests: You’ll have blood tests every month to check if you’re getting enough dialysis.
Adjustments: Your doctor might change your dialysis plan based on how you’re doing.
Monitoring for Complications: You’ll learn to watch for signs of infection or other problems.
Lifestyle Changes: You might need to make some changes to your diet and daily routine.

Recovery and Living with Peritoneal Dialysis

Getting used to peritoneal dialysis takes time, but many people find they can lead full, active lives. Here’s what you can expect:

Daily Routine: You’ll need to plan your day around your exchanges. Most people find they can still work, travel, and enjoy their hobbies.
Diet: You’ll need to watch what you eat and drink. Your dietitian will help you plan meals that keep you healthy.
Exercise: Regular exercise is important. Talk to your doctor about what activities are safe for you.
Work: Many people on peritoneal dialysis continue working. You might need to adjust your schedule a bit.
Travel: You can travel with peritoneal dialysis. Your care team can help you plan for trips.

Long-term Management

Living well with peritoneal dialysis involves ongoing care:

Regular Check-ups: You’ll see your kidney doctor every few months.
Monitoring Your Health: Keep track of your weight, blood pressure, and how you feel.
Catheter Care: You’ll need to keep your catheter site clean to prevent infections.
Supply Management: You’ll learn to order and store your dialysis supplies at home.
Emotional Support: It’s normal to have ups and downs. Don’t hesitate to seek support from family, friends, or a counselor.

Remember, many people live for years on peritoneal dialysis. With good care and a positive attitude, you can maintain a good quality of life.

Risks and Complications of Peritoneal Dialysis

While peritoneal dialysis is generally safe, it’s important to be aware of potential risks:

Risks

Infection: The most common risk is peritonitis, an infection in your belly. Good hygiene helps prevent this.
Weight Gain: The sugar in the dialysis fluid can cause weight gain.
Hernia: The pressure from the fluid in your belly can sometimes cause a hernia.

Complications

Catheter Problems: Sometimes the catheter can move out of place or get blocked.
Fluid Balance Issues: You might retain too much fluid or lose too much, affecting your blood pressure.
Nutritional Concerns: You might lose protein through the dialysis process.

It’s important to remember that while these risks exist, most can be managed or prevented with proper care and monitoring.

Benefits of Peritoneal Dialysis

Peritoneal dialysis offers several benefits that can significantly improve your quality of life:

Freedom and flexibility: You can do your treatments at home, work, or while traveling, giving you more control over your schedule.
Continuous therapy: Because you’re doing dialysis every day, it’s gentler on your body compared to the ups and downs of in-center hemodialysis.
Better blood pressure control: Many people on peritoneal dialysis have better blood pressure control and need fewer blood pressure medications.
Preserves remaining kidney function: Some studies suggest that peritoneal dialysis might help preserve any remaining kidney function longer than hemodialysis.
Fewer dietary restrictions: You might have more flexibility in what you can eat and drink compared to hemodialysis.
No needles: Unlike hemodialysis, peritoneal dialysis doesn’t require needle sticks for each treatment.
Easier travel: You can take your supplies with you, making it easier to travel for work or pleasure.
More energy: Many people report feeling more energetic because their blood is being cleaned continuously.
Better sleep: If you choose automated peritoneal dialysis, the machine works while you sleep, leaving your days free.

Potential for better outcomes: Some studies suggest that people who start with peritoneal dialysis might have better long-term outcomes if they later need a kidney transplant.

Conclusion: Taking Control of Your Kidney Health

Living with kidney disease and undergoing peritoneal dialysis can feel overwhelming at first, but with the right information and support, many people lead fulfilling, active lives. Remember, peritoneal dialysis is not just a treatment—it’s a lifestyle change that empowers you to take an active role in your health. It may take some time to adjust, but with patience and support from your healthcare team, family, and friends, you can adapt to this new chapter in your life.
