Hemodialysis is a type of treatment that aims to promote blood filtration when the kidneys do not function properly, thus favoring the elimination of excess sales of toxins, minerals and liquids.
This treatment should be indicated by a nephrologist and is usually done in people with renal impairment, and should be performed in hospital or hemodialysis clinics. The duration and frequency of dialysis sessions can vary from severity to severity of kidney failure, and 4-hour sessions. can be indicated 3 to 4 times per week.
- Hemodialysis is performed according to nephrologist’s advice and aims to filter blood.
- Eliminate toxic substances.
- Such as urea; excess mineral substances.
- Such as sodium and potassium; and filter out excess water from the body.
This procedure may be indicated in cases of acute renal failure because there is sudden renal failure over time, also in cases of chronic renal failure, as renal functions need to be permanently replaced. Learn what kidney failure is, what symptoms and causes it is.
Hemodialysis is performed by a marking device, which circulates blood and passes through a filter that removes substances that circulate excessively and may be harmful to the body; are possible by the presence of a specific membrane responsible for overcoming this function.
The blood that will leak is sold through a catheter inserted into the blood vessels, after filtering, cleaning the blood, without toxins and less fluids, returns to the bloodstream through another catheter.
In people who require hemodialysis frequently, it is possible to perform a small surgery to attach a vein to an artery, thus forming an arterio-vein fistula, which then becomes a vessel with high blood flow and high resistance to repeated punctures, facilitating the procedure. . .
In the case of chronic kidney failure, when the kidneys are not functioning properly, renal replacement treatment should be maintained for the duration of the kidney transplant.
However, there are cases of acute kidney failure in which the kidneys function abruptly and temporarily, such as in the case of a serious infection, drug poisoning or cardiac complication, for example, where only one may be needed. Some dialysis sessions cause your kidneys to return to work normally.
Hemodialysis does not fully support kidney function, and some vitamins are stored during dialysis, so the nephrologist may indicate treatment with calcium, vitamin D, iron, erythropoietin and antihypertensives, which can help control blood pressure.
Similarly, the person needs to take care of food, monitor fluid intake, sales, and correctly choose the types of foods they eat daily, as hemodialysis should be scheduled at that time, so follow-up with a nutritionist is also recommended. .
In most hemodialysis sessions, the patient will not experience any discomfort, however, sometimes some complications may occur such as:
For these reasons, hemodialysis is always done in the presence of a doctor and nursing team.
In the case of also, there may be a loss of fistula, resulting in a blockage of blood flow. To prevent this from happening, it is recommended to take certain precautions, such as not measuring pressure, drawing blood, or applying medication to the fistula arm.
In the case of bruising in the area, it is recommended to use cold companies during the day and shin guards in the following days. In addition, if you feel that the flow in the fistula is decreasing, it is necessary to contact the companion. nurse in the doctor, as this is a sign of dysfunction.
