Difference between hemodialysis and peritoneal dialysis

Home peritoneal dialysis uses the lining on the inside of the belly, called your peritoneum, as a natural filter for blood. During home PD, dialysate fluid is placed in your peritoneal cavity using a The fluid stays in your peritoneum for a period of called, “dwell time,” while the dialysate absorbs the waste, toxins, and excess fluid from your blood. When the dialysate is drained from your peritoneal cavity, the waste, toxins, and excess fluid are removed along with it. The completion of this peritoneal dialysis procedure—filling, dwelling, and draining—is called an exchange. Home PD is designed to be done daily, and as a result can be a gentler treatment since this option acts more closely to the natural around-the-clock function of a kidney. Your doctor will work with you to create the right dialysis schedule for you. Home HD filters your blood outside of your body through a dialyzer or “artificial kidney machine” to remove unwanted waste, toxins, and excess fluids. Your blood travels through plastic tubing to the dialyzer, where it is cleaned using a solution called dialysate to get rid of these unwanted substances. Clean, chemically balanced blood is then returned to your body. Home HD requires a permanent Both home PD and home HD offer the option of more frequent dialysis, as ordered by your physician, which can mean lower risk of health complications, feeling better, and having more energy to do the things you love. Both options may also mean fewer food restrictions...

Background Nutritional factors are associated with high mortality and morbidity in dialysis patients, and protein-energy wasting is regarded as an important one. The modality of dialysis may affect patients’ dietary behavior and nutritional status, but no study has compared the dietary behavior, nutrient intake, and nutritional adequacy of hemodialysis (HD) and peritoneal dialysis (PD) patients. Methods From December 2016 to May 2017, a dietary behavior survey and Semi-quantitative Food Frequency Questionnaire (Semi-FFQ) were conducted on 30 HD patients and 30 PD patients in Ewha Womans University Mokdong Hospital, and laboratory parameters were obtained. The results of prevalent HD and PD patients were then compared. Results The mean age of HD patients was higher than that of PD patients; HD: 58.5 ± 9.1 years, PD: 49.3 ± 9.7 years ( p = 0.001). In the dietary behavior survey, HD patients showed more appropriate dietary behavior patterns overall than PD patients. In the dietary intake analysis with the Semi-FFQ, energy intake was significantly lower in the PD group than in the HD group due to the lower intake of carbohydrates, fat, and protein. A comparison of nutrient intake-to-recommended allowance ratio between the HD and PD groups revealed that the HD group showed higher nutrient intake than the PD group. Serum albumin and potassium levels were significantly higher in HD than in PD patients. Conclusion According to this study, the dietary behavior a...

Background Diabetes has become the most common cause of end-stage renal disease (ESRD) requiring renal replacement therapy (RRT) in most countries around the world. Peritoneal dialysis (PD) is valuable for patients newly requiring RRT because of the preservation of residual renal function (RRF), higher quality of life, and hemodynamic stability in comparison with hemodialysis (HD). A previous systematic review produced conflicting results regarding patient survival. As several advances have been made in therapy for diabetic patients receiving PD, we conducted a systematic review of studies published after 2014 to determine whether incident PD or HD is advantageous for the survival of patients with diabetes. Methods For this systematic review, the MEDLINE, EMBASE, and CENTRAL databases were searched to identify articles published between February 2014 and August 2017. The quality of studies was assessed using the GRADE approach. Outcomes of interest were all-cause mortality; RRF; major morbid events, including cardiovascular disease (CVD) and infectious disease; and glycemic control. This review was performed using a predefined protocol published in PROSPERO (CRD42018104258). Results Sixteen studies were included in this review. All were retrospective observational studies, and the risk of bias, especially failure to adequately control confounding factors, was high. Among them, 15 studies investigated all-cause mortality in diabetic patients initiating PD and HD. Difference...

• You place about 2 quarts of cleansing fluid into your abdomen and, later, drain it. This is done by connecting a plastic bag of the fluid, called dialysate, to the soft tube (PD catheter) in your abdomen. • By raising the plastic bag to shoulder level, gravity pulls the fluid into your abdomen. This is called “filling.” When empty, the plastic bag is removed and thrown away. • The cleansing fluid (dialysate) stays inside your abdomen for several hours. This is called “dwelling.” During this time, the waste products and extra fluid move out of your blood through the peritoneum membrane and into the dialysate. • When it’s finished, the dialysate is drained from your abdomen through the PD catheter into a plastic bag, which can be secured and thrown away. This is called “draining.” • The process of these 3 steps—filling, dwelling and draining—is called “an exchange.” • The actual time for filling or draining takes about 30 minutes. It’s done during your regular daily activities. Because you do an exchange 3, 4 or 5 times in a 24-hour period, some people like to do their exchanges around mealtimes and at bedtime. 5 things I wish I knew about PD before I started • PD becomes routine. Just like brushing your teeth or making coffee, doing PD will become part of your daily routine and start to feel normal. • Traveling and keeping up with PD is easy. Whether you take your portable cycler or do manual treatments throughout the day, just work PD into your schedule like you do at ho...

What is renal failure? Renal failure refers to temporary or permanent damage to the kidneys that results in loss of normal kidney function. There are two different types of renal failure--acute and chronic. Acute renal failure has an abrupt onset and is potentially reversible. Chronic renal failure progresses slowly over at least three months and can lead to permanent renal failure. The causes, symptoms, treatments, and outcomes of acute and chronic are different. Conditions that may lead to acute or chronic renal failure may include, but are not limited to, the following: Acute renal failure Chronic renal failure Chronic renal failure Chronic renal failure Rhabdomyolysis. Kidney damage that can occur from muscle breakdown. This condition can occur from severe dehydration, infection, or other causes. Chronic renal failure Chronic renal failure Decreased blood flow to the kidneys for a period of time. This may occur from blood loss or shock. Chronic renal failure Chronic renal failure An obstruction or blockage along the urinary tract. Chronic renal failure Chronic renal failure A prolonged urinary tract obstruction or blockage. Chronic renal failure Chronic renal failure Alport syndrome. An inherited disorder that causes deafness, progressive kidney damage, and eye defects. Ingestion of certain medications that may cause toxicity to the kidneys. Chronic renal failure Chronic renal failure Chronic renal failure Chronic renal failure Any condition that may impair the flow of...

Did you know that chronic kidney disease affects an estimated 37 million people in the United States ? Kidney disease poses various health concerns and complications and, if left untreated, it can even be fatal. The most effective way to treat kidney failure is through dialysis. There are two different types of dialysis: hemodialysis and peritoneal dialysis . In this guide, we’ll explain everything you should know about hemodialysis and peritoneal dialysis. Click a section to jump directly to it! • • • • ​ Which type of dialysis type is right for me? • • To better understand the differences between hemodialysis and peritoneal dialysis, it's important to thoroughly understand what the kidneys do and why they are significant . Your kidneys are crucial to filtering waste and harmful substances out of the bloodstream. They absorb essential vitamins and nutrients, expelling everything else out of the body in the form of urine. The kidneys also regulate your body's hydration levels and assist in hormone production. If your kidneys fail, they allow harmful elements into the bloodstream, leading to complications with the central nervous system, diabetes, heart problems, and more. You may also experience some common symptoms of kidney failure, such as nausea, vomiting, decreased urine output, fatigue, swelling from fluid retention, and more. If your kidneys no longer remove enough waste and fluid from your blood to keep you healthy, your doctor may recommend dialysis treatments. Di...

Posted September 20, 2018 in Tags: In any situation, there are pros and cons when deciding between two options. Making the decision for which form of The table below is a brief comparison including the components of kidney diets for HD and PD. Read further for a more detailed description. Diet Component HD PD High Protein Yes Yes High Calorie Yes No Low Potassium Yes No Low Phosphorus Yes Yes Low Sodium Yes Yes Fluid Restriction Yes No Protein in PD and HD Kidney Diets Increased dietary intake of Calories Those receiving HD have increased Potassium Potassium is one of the nutrients the kidney are in charge of removing from the body. When they are no longer functioning, Phosphorus Phosphorus is another nutrient the kidneys remove from the body. While dialysis cleans some potassium, it does not remove a lot of phosphorus. Both PD and HD patients are encouraged to follow a low Sodium It is recommended to keep sodium intake between 2000-3000 mg daily. Limiting Fluid When the kidneys are not working, they are not removing excess fluid. Intake of The kidney diet can seem overwhelming. There are parts that overlap like avoiding processed meat helps decrease phosphorus as well as sodium. Think of each of these as a guideline rather than a restriction.
