What is a Fistula?

Published by admin under Renal Info,dialysis

A fistula is created surgically bi directly connecting one of the arteries to one of the veins. It is constructed by a surgical procedure under local anesthesia and lies completely under the skin, usually near the wrist or the elbow. Arteries are located deep under the skin and have a fast pulsating flow. Normally, the veins are smaller than the arteries. By joining them, the blood from the artery flows directly to the vein, and the vein becomes larger and is called a”fistula”. This makes the insertion of the two needles required for the dialysis much easier. During dialysis, a member of the nursing or technician staff cleans the area overlying the internal fistula. The skin may be numbed with a local anesthetic and two needles are inserted into the vessels, one in the artery portion of the fistula to take blood from you to the dialyzer and one in the vein portion of the fistula to return the blood from the artificial kidney to you. The needles are attached to tubes that carry the blood to the dialyzer and then back to the body. After the vascular surgeon creates the internal fistula, it often takes several weeks for the veins to become large enough for the needles to enter them easily. The doctor may give you instructions on how to help the veins enlarge so they can be used. Fistulas can clot or become infected, but do so infrequently. Signs of clotting can include disappearance of the vein’s pulsation; the sound of blood moving through the vessels; pain; and swelling. Signs of infection include redness, swelling and fever. You should contact your physician if this happens.

Dangers of Nephrotoxins in the Workplace

Published by admin under Renal Info

Is your current job putting your kidney health at risk?

According to Clinical Renal Toxicology…

“Chemicals can affect the renal function or structures through a direct toxic action or through various systemic effects, such as intravascular hemolysis, rhabdomyolysis, or cardiac failure.”

Such chemicals include:

  • Lead
  • Cadmium
  • Mercury
  • Silica

Certain occupations are far more at risk than others. For instance, individuals that work in brazing or nickel-cadium battery manufacturing are exposed to high levels of Cadium. However, someone working in scrap metal recycling in Los Angeles would also likely be exposed to Cadium in the process of recovering the metal, but not as much as the person working in the manufacturing of nickel-cadium batteries.

Lead is another one you really want to watch out for. Occupations most notorious for causing lead exposure are lead battery manufacturing, soldering, smelting, radio repair, glass & ceramic manufacturing, and also paint stripping (in the case of lead-based paints).

If you are concerned about the health risks associated with your current occupation, especially pertaining to renal health, consult your employer. He or she should have additional details.

Who Administers Hemodialysis?

Published by admin under Renal Info,dialysis



In general, hemodialysis is performed in a dialysis center by technicians trained in the care of patients who are supervised by nurses. Medicare pays three hemodialysis treatments per week. If you choose to undergo treatment at a center, it will be for a fixed schedule, three times a week, on Mondays, Wednesdays and Fridays or Tuesdays, Thursdays and Saturdays. If you get the schedule of your choice, you may request to be put on a waiting list for a schedule of your choice. In special cases, you may exchange your time with someone else. You will need to plan well your dialysis program if you work or have children to care. Some centers provide dialysis treatments during the night in the middle. This treatment is done over a longer period at night, while sleeping in the middle. This type of dialysis reduces the limitations on food and fluid intake, and also it provides more time during the day to work, care for their children and do hobbies and other activities.

You can choose to learn to make their own hemodialysis treatments at home. When you are the only patient, it may become more frequent dialysis treatments or lasting almost replaced the normal work performed by healthy kidneys. Daytime hemodialysis at home (DHHD for short in English) is performed 5-7 days a week for 2 to 3 hours per session and you organize the schedule. If your health insurance plan would pay more than three treatments, you could be brief treatments during the morning or afternoon. Nocturnal home hemodialysis (NHHD by its acronym in English) is done in 3-6 nights a week while you sleep. Whether you choose the DHHD or NHHD, this will allow food and a normal fluid intake, with fewer blood pressure medications and other health problems. Most programs ask patients to do home hemodialysis have a skilled attendant during treatments. Learning to be hemodialysis is like learning to drive a car: it takes a few weeks and, initially, is alarming but then becomes a routine. The dialysis center provides the equipment and training, and assistance by phone 24 hours if you have any questions or problems. New machines for home dialysis are smaller and easier to use than the equipment used in schools.

You have options of dialysis centers and many cities have more than one site to choose from. You can visit a center to see if there are treatments you want or the time it needs. Some centers allow the use of laptops or cell phones or receive visits, others not. Medicare has a list of all centers in the United States on its Web site at www.medicare.gov / dialysis (in English), which shows the quality ratings of each school. Your health plan may have a list of sites where you can go. If you choose a treatment option in a school, it must be near your home to reduce your travel time. If the treatment is done at home, once you are trained, you should only go to the center once a month. So, the center can be as far as you want to travel once a month.

Possible Complications of Dialysis
Vascular access problems are the most common reason for hospitalization among people receiving hemodialysis. Some common problems include infection, blockage by clotting and poor circulation. These problems may prevent their treatments to succeed. You might have to undergo repeated surgeries to achieve a properly functioning access.

Other problems may be caused by rapid changes in water and chemical balance of your body during treatment. Muscle cramps and hypotension (a sudden drop in blood pressure) are two common side effects. Hypotension can make you feel weak, dizzy or sick to your stomach.

Probably need a few months to adjust to hemodialysis. Side effects can often be dealt with swiftly and easily, so you should inform your doctor and dialysis staff suffered any side effects. You can avoid many side effects if you follow a proper diet, limiting fluid intake and taking medications as directed.
