Using A Cycler For Automated Peritoneal Dialysis Exchanges

MHS HSC Biology – Comparing Renal Dialysis to Kidney Function

In automated peritoneal dialysis, you use a machine called a cycler to fill and drain your belly. You can program the cycler to give you different amounts of dialysis solution at different times.

Each evening, you set up the machine to do three to five exchanges for you. You connect three to five bags of dialysis solution to tubing that goes into the cyclerone bag of solution for each exchange. The machine may have a special tube to connect the bag for the last exchange of the night.

At the times you set, the cycler

  • releases a clamp and allows used solution to drain out of your belly into the drain line
  • warms the fresh dialysis solution before it enters your body
  • releases a clamp to allow body-temperature solution to flow into your belly

A fluid meter in the cycler measures and records how much solution the cycler removes. Some cyclers compare the amount that was put in with the amount that drains out. This feature lets you and your doctor know if the treatment is removing enough fluid from your body.

Some cyclers allow you to use a long drain line that drains directly into your toilet or bathtub. Others have a disposal container.

The Consequences Of Kidney Damage Or Disease

The kidney is responsible for the removal of waste products from the blood. Damage from accidents or disease can lead to a build-up of poisonous wastes in the body. Humans can survive with one kidney, but for people who suffer from total kidney failure this would be fatal if not treated. Treatment is available for kidney failure and can be by organ transplant or by using kidney dialysis.

In this procedure, patients are connected to a dialysis machine which acts as an artificial kidney to remove most of the urea and restore/maintain the water and ion balance of the blood.

Patients with kidney failure can be kept alive by using kidney dialysis until a transplant becomes available, but they have several disadvantages:

  • they are expensive
  • the patient must have his or her blood connected to the machine for several hours every week
  • patients must follow a very rigid diet to avoid complications
  • they only work for a limited time for a patient

Chronic Kidney Disease: When Is The Best Time To Start Dialysis

Dialysis is usually started as soon as the kidneys fail and the resulting typical symptoms occur. But as long as you dont have severe symptoms, you can wait before starting dialysis that can help to prepare for it better.

The last stage of chronic kidney disease is also referred to as end-stage renal disease. If the kidneys can no longer do their job properly, harmful substances build up inside the body . The typical symptoms of kidney failure include:

  • Weight loss
  • Skin discoloration and a urine-like body odor
  • Shortness of breath, chest pain, irregular pulse
  • Confusion and loss of consciousness

Facts & Figures Of Chronic Kidney Disease

Your kidneys’ primary function is to filter and excrete waste products. To find out how well your kidneys are doing, we measure the quantity of waste that circulates in your blood.

This is a test used to check how well the kidneys are working by estimating how much waste is in your blood. The more waste products in your blood the lower the filtration rate.

Your health care team will show you how to keep your catheter clean to prevent infections. Here are some general rules:

  • Store your supplies in a cool, clean, dry place.
  • Inspect each bag of solution for signs of contamination, such as cloudiness, before you use it.
  • Find a clean, dry, well-lit space to perform your exchanges.
  • Wash your hands every time you need to handle your catheter.
  • Clean your skin where your catheter enters your body every day, as instructed by your health care team.
  • Wear a surgical mask when performing exchanges.

Incremental Hd And Combined Diet And Dialysis Programs

Incremental dialysis refers to smooth transition from CKD to dialysis therapy. When compared to the conventional thrice-weekly schedule, incremental HD in the first 3 months is associated with greater preservation of RKF and urine volume and lower interdialytic weight gain independent of other clinically relevant factors .

Despite the potential benefits that incremental dialysis brings, an individualized approach is required for patients on this protocol. Kalantar-Zadeh et al. have proposed eleven criteria to screen incident ESRD patients as suitable candidates for incremental HD . Two were considered mandatory and 5 additional criteria among the remaining 9 were required.

Table 4.

Incremental HD treatment criteria

Recent strategies have been proposed to quantify guidelines for incremental practice. In relatively healthy patients, HD can be started once weekly, while renal urea clearance is between 4 and 5 mL/min/1.73 m2. This can be increased to twice weekly when Kru is between 2 and 4 mL/min/1.73 m2 and thrice weekly when Kru falls below 2 mL/min/1.73 m2 .

Despite all the promising benefits, larger size, double-blinded, and randomized clinical trials are warranted to validate the long-term safety and implications of this approach to dialysis transition.

How Do I Prepare For Dialysis

Before your first dialysis treatment, your doctor will surgically implant a tube or device to gain access to your bloodstream. This is typically a quick operation. You should be able to return home the same day.

Its best to wear comfortable clothing during your dialysis treatments. Also follow your doctors instructions. These may include fasting for a certain amount of time before the treatment.

Both hemodialysis and peritoneal dialysis can be performed at home. Peritoneal dialysis can be performed alone, while hemodialysis requires a partner. The partner can be a friend or family member, or you can opt to hire a dialysis nurse.

With either type of treatment, youll receive thorough training from a medical professional beforehand.

Doing An Exchange By Hand

  • After you wash your hands and put on your surgical mask, drain the used dialysis solution from your belly into the drain bag. Near the end of the drain, you may feel a mild tugging sensation that tells you most of the fluid is gone. Close the transfer set.
  • Warm each bag of solution to body temperature before use. You can use an electric blanket, or let the bag sit in a tub of warm water. Most solution bags come in a protective outer wrapper, and you can warm them in a microwave. Dont microwave a bag of solution after you have removed it from its wrapper.
  • Hang the new bag of solution on a pole and connect it to the tubing.
  • Remove air from the tubesallow a small amount of fresh, warm solution to flow directly from the new bag of solution into the drain bag.
  • Clamp the tube that goes to the drain bag.
  • Open or reconnect the transfer set, and refill your belly with fresh dialysis solution from the hanging bag.

What Is Needed To Prepare For Dialysis

How To Improve Kidney Function & Avoid Dialysis Video #2. The One Supplement For Kidney Disease

Dialysis is a treatment that you have for the rest of your life and it becomes a part of your everyday routine. Even the decision of which method is the best for you personally will take some time to make. That also applies to the preparations such as the surgical procedures that are necessary. For peritoneal dialysis, a needs to be inserted into the abdominal cavity and attached to the abdominal wall. After a recovery period of two to four weeks, peritoneal dialysis can be started. For hemodialysis, an arteriovenous fistula needs to be created using surgery. This is a connection between a vein and an artery in the forearm that is used to access the bloodstream in hemodialysis. Its best to plan the procedure several months before starting dialysis. This is because several examinations need to be done first, and the shunt needs several weeks to develop so that it can be used over the long term.

Creating a shunt apparently works better if you are first transferred to a kidney specialist long enough before dialysis is started. That is what researchers from the found based on 15 studies with a total of about 5,600 participants. Complications such as shunt infections were less common too. By analyzing other studies, the researchers also found out that life expectancy increases when a kidney specialist is involved early on.

Should I Keep Taking My High Blood Pressure Medication

Hypertension is a common cause of kidney problems. Hypertension damages the blood vessels of the kidneys and affects their ability to filter the blood. Kidneys also help to regulate blood pressure, so kidney damage can make hypertension worse. Over time, hypertension can cause kidney failure.

If you are living with hypertension, you might take medication for the problem. You may be reading news reports questioning the safety of taking certain prescription medicines to manage their condition: ACE inhibitors and angiotensin receptor blockers .

Sperati says that patients should stay on their medications and discuss concerns with their doctors.

Right now there are two sides debating this issue. One side is saying, based on animal studies, that these medications might be harmful, increasing risk of infection. The other says these same drugs might protect against lung damage and other problems associated with COVID-19.

But all of the professional societies have published articles recommending that you not change your medications, he says. Staying the course with your prescriptions, he adds, can lower the risk of heart and kidney damage from unchecked high blood pressure.

Sperati does recommend that patients with kidney issues stay away from non-steroidal anti-inflammatory drugs , such as ibuprofen and naproxen. These can raise blood pressure and increase fluid volume in the body, which puts strain on the kidneys.

What Are The Symptoms Of Kidney Failure

Symptoms of kidney failure may begin so slowly that you dont notice them right away.

Healthy kidneys prevent the buildup of wastes and extra fluid in your body and balance the salts and minerals in your bloodsuch as calcium, phosphorus, sodium, and potassium. Your kidneys also make hormones that help control blood pressure, make red blood cells, and keep your bones strong.

Kidney failure means your kidneys no longer work well enough to do these jobs and, as a result, other health problems develop. As your kidney function goes down, you may

  • have swelling, usually in your legs, feet, or ankles
  • get headaches
  • feel itchy
  • feel tired during the day and have sleep problems at night
  • feel sick to your stomach, lose your sense of taste, not feel hungry, or lose weight
  • make little or no urine
  • have muscle cramps, weakness, or numbness
  • have pain, stiffness, or fluid in your joints
  • feel confused, have trouble focusing, or have memory problems

Following your treatment plan can help you avoid or address most of these symptoms. Your treatment plan may include regular dialysis treatments or a kidney transplant, a special eating plan, physical activity, and medicines.

Coronavirus Kidney Damage: A Serious Sign

Organ systems like the heart, lungs, liver and kidneys rely on and support one another’s functions, so when the new coronavirus causes damage in one area, others might be at risk. The kidneys essential functions have an impact on the heart, lungs and other systems. That may be why doctors note that kidney damage arising in patients with COVID-19 is a possible warning sign of a serious, even fatal course of the disease.

Dialysis: All You Need To Know

You can do both CAPD and automated peritoneal dialysis in any clean, private place, including at home, at work, or when travelling.

Before you travel, you can have the manufacturer ship the supplies to where youre going so theyll be there when you get there. If you use automated peritoneal dialysis, youll have to carry your machine with you or plan to do exchanges by hand while youre away from home.

How Long Will I Need Dialysis For

It depends. In some cases, kidney failure may be a temporary problem and dialysis can be stopped when your kidneys recover.

But often, someone with kidney failure will need a kidney transplant.

It’s not always possible to carry out a kidney transplant straight away, so dialysis may be needed until a suitable donor kidney becomes available.

If a kidney transplant is not suitable for you for example, because you’re not well enough to have a major operation dialysis may be needed for the rest of your life.

Packaged Instant And Premade Meals

Processed foods can be a major component of sodium in the diet.

Among these foods, packaged, instant, and premade meals are usually the most heavily processed and thus contain the most sodium.

Examples include frozen pizza, microwaveable meals, and instant noodles.

Keeping sodium intake to 2,300 mg per day may be difficult if youre eating highly processed foods regularly.

Heavily processed foods not only contain a large amount of sodium but also commonly lack nutrients .

SUMMARY

Packaged, instant, and premade meals are highly processed items that can contain very large amounts of sodium and lack nutrients. Its best to limit these foods on a renal diet.

Swiss chard, spinach, and beet greens are leafy green vegetables that contain high amounts of various nutrients and minerals, including potassium.

When served raw, the amount of potassium varies between 140290 mg per cup .

While leafy vegetables shrink to a smaller serving size when cooked, the potassium content remains the same.

For example, one-half cup of raw spinach will shrink to about 1 tablespoon when cooked. Thus, eating one-half cup of cooked spinach will contain a much higher amount of potassium than one-half cup of raw spinach.

Raw Swiss chard, spinach, and beet greens are preferable to cooked greens to avoid too much potassium.

However, moderate your intake of these foods, as theyre also high in oxalates. Among sensitive individuals, oxalates can increase the risk of kidney stones (

What Is Dialysis And Chronic Kidney Disease

It is estimated that more than 31 million American adults have chronic kidney disease . However, a survey done by the National Medical Association and Amgen shows that most adults know very little about the symptoms or treatment of the disease.

How can people be so unaware of a disease that affects so many? Like diabetes and high blood pressure, chronic kidney disease is called a silent killer because there are few symptoms and by the time a person realizes they have a problem, much damage has already been done.

How do normal kidneys function?

To understand how chronic kidney disease can go unnoticed, lets take a look at how normal kidneys function and then learn how efficiently they can work even when they are damaged.

Most people are born with two kidneys. The kidneys are about the size of a closed fist. They are located in the middle back above the waist, with one on each side of the spine. The right kidney is a little lower and smaller to make room for the liver.

Most people think that the kidneys are only responsible for making urine, but there are more functions of the kidneys that affects many areas of the body.

A health kidney is responsible for:

  • cleaning the blood
  • balancing fluids, minerals and chemicals in the body
  • signaling the bones to make red blood cells

  • Many Patients With Kidney Failure Regret Initiating Dialysis

    Kidney dialysis vs Kidney function

    by American Society of Nephrology

    Results from a new study indicate that many patients with kidney failure regret initiating dialysis, and those who choose dialysis to please their doctors or family members may be more likely to experience regret. The findings appear in an upcoming issue of CJASN.

    Sometimes patients experience regret when they reflect on a decision they’ve made about their medical care, and this can negatively affect their quality of life. For patients with kidney failure who cannot receive a transplant and are contemplating dialysis, it’s important to have discussions with kidney specialists and other experts who can explain the impacts that dialysis may have on their lives.

    Because few studies have examined regret in patients after they’ve started dialysis as a treatment for kidney failure, a team led by Fahad Saeed, MD and Paul R. Duberstein, Ph.D. analyzed survey responses related to regret in patients receiving maintenance dialysis from 7 dialysis units in the Cleveland, Ohio area.

    Eighty-two of 397 respondents reported regret that they decided to initiate dialysis. There were no significant demographic factors linked with regret. Regret was more common when patients reported choosing dialysis to please doctors or family members. Patients who reported discussing life expectancy with their doctors and those who had completed a living will were less likely to report regret that they started dialysis.

    Supportive Care For Kidney Failure

    Supportive care is the treatment choice for kidney failure for people who have decided that dialysis and transplant are not appropriate for them. For many, this is because they are already very frail and they do not want complex treatments. Some people have the complex treatment for a while and then wish to stop.For many who are already frail, their lifespan with kidney failure, with or without dialysis, is very similar. Supportive care means that the person’s care continues to be supervised and supported by health professionals. They may have medication and a restricted diet to improve their quality of life. Supportive care, however, will not artificially prolong life when your kidneys fail completely. If a person is unsure about choosing a treatment option, it is always possible to try dialysis for a short while to see how things go.
