In hemodialysis, a machine filters wastes, salts and fluid from your blood when your kidneys are no longer healthy enough to do this work adequately. Hemodialysis (he-moe-die-AL-uh-sis) is one way to treat advanced kidney failure and can help you carry on an active life despite failing kidneys.
Dialysis is a treatment for people whose kidneys are failing. When you have kidney failure, your kidneys don't filter blood the way they should. As a result, wastes and toxins build up in your bloodstream. Dialysis does the work of your kidneys, removing waste products and excess fluid from the blood.
About Dialysis
Dialysis is a type of treatment that helps your body remove extra fluid and waste products from your blood when the kidneys are not able to.
Patients treated with hemodialysis (HD) may experience acute complications during dialysis. These include cardiac arrhythmias, intradialytic hypotension or hypertension, dialysis disequilibrium syndrome, reactions to the HD membrane, air embolism, bleeding, and seizures.
While the USRDS reports cardiovascular disease and infections as the leading CODs among dialysis patients [7], we found that KPSC death records indicated diseases of the circulatory system (35.7%), endocrine/nutritional/metabolic disease (24.2%), and diseases of the genitourinary system (12.9%) to be the three most ...
According to the National Kidney Foundation, the average life expectancy for a patient on dialysis is 5-10 years. Though for someone between the ages of 70 and 74, life expectancy is closer to four years on dialysis.
Since fluid is removed from your body during hemodialysis, drinking more fluids than recommended between hemodialysis treatments may cause life-threatening complications, such as heart failure or fluid accumulation in your lungs (pulmonary edema). Inflammation of the membrane surrounding the heart (pericarditis).
Fluid overload occurs when there is too much fluid build-up in the body during dialysis, as the kidneys are no longer able to remove enough on their own. This can result in additional swelling, bloating, cramping, high blood pressure, shortness of breath and heart problems.
The dialysis machine cleans your body's blood when your kidneys stop working well. Transplant means to move from one place to another. For kidneys this means that a healthy kidney is taken from one person's body and put into someone's body whose kidneys have stopped working.
To see how well kidney dialysis is working, your care team can check your weight and blood pressure before and after each session. Regular blood tests, such as those measuring blood urea nitrogen and creatinine levels, and other specialized evaluations also help assess the effectiveness of treatment.
For example, hemodialysis patients who treat three times per week are more likely to experience abnormal heart rhythms during their first treatment of the week, when the total fluid in their body is typically at its highest.
Although dialysis is needed because of CKD, heart disease is the most common cause of death for someone on dialysis. This is because when kidneys don't function properly, the heart has to work harder to circulate blood, leading to high blood pressure and possibly heart disease.
Missing dialysis treatments places you at risk for building up high levels of these 2 minerals: High potassium, which can lead to heart problems including arrhythmia, heart attack, and death. High phosphorus, which can weaken your bones over time and increase your risk for heart disease.
Acute kidney injury (AKI) causes hemodynamic-, humoral-, and immunologic changes, which leads to dysfunction of distant organs including lung, heart, brain, liver, intestine and immune system.
Their sudden deaths may be related to symptoms associated with chronic kidney disease itself such as vascular calcification, left ventricular hypertrophy, electrolyte/fluid abnormalities, autonomic dysfunction or inflammation.
The kidneys usually start working again within several weeks to months after the underlying cause has been treated. Dialysis is needed until then. If the kidneys fail completely, the only treatment options available are dialysis for the rest of your life or transplant.
Removing excessive fluid gain can make treatment uncomfortable. Patients can experience a sudden drop in blood pressure, which usually occurs toward the end of a dialysis treatment. You may feel nauseated, weak and tired because your body may not be used to having so much fluid removed at once.
Several studies have shown a decreased quality of life and increased depression in the hemodialysis patient population.
Patients may experience a wide variety of symptoms as kidney failure progresses. These include fatigue, drowsiness, decrease in urination or inability to urinate, dry skin, itchy skin, headache, weight loss, nausea, bone pain, skin and nail changes and easy bruising.
Most dialysis patients need to limit their fluid intake to 32 ounces per day. Manage your thirst. Your dietitian can help you find ways to manage your thirst such as sugar-free hard candies, ice chips, or frozen grapes. This will help you avoid drinking too much fluid between dialysis treatments.
Hemodialysis patients carry a large burden of cardiovascular disease; most onerous is the high risk of sudden cardiac death.
End-stage kidney disease (ESKD) is the last stage of long-term (chronic) kidney disease. This is when your kidneys can no longer support your body's needs. End-stage kidney disease is also called end-stage renal disease (ESRD).
Someone who starts dialysis in their late 20s can expect to live for up to 20 years or longer, but adults over 75 may only survive for 2 to 3 years.
