What is hemodialysis? At what diseases is applied?

  1. People who have done dialysis for years could get rid of the need for dialysis in a few months
  2. people with chronic kidney failure generally all their lives should receive these procedures.
  3. Cleansing the kidneys.
  4. Method for renal purification of blood in acute and chronic renal failure. Kidney diseases.
  5. still used for poisoning, peritonitis, sepsis.
  6. Hemodialysis is one of the methods of extrarenal blood purification. It is based on the principle of the penetration of substances through a semipermeable membrane, which allows removing toxic substances and metabolic products from the blood. The need for hemodialysis occurs in severe kidney disease or when more toxins enter the bloodstream than healthy kidneys can infer (for example, in case of poisoning).
    Indications for use
    The need for hemodialysis is established by doctors depending on the diagnosis and condition of the patient.
    The main indications for hemodialysis are:
    acute and chronic renal failure;
    - poisoning with dialysis poisons (unfortunately, not all toxic substances can be removed from the body by this method);
    - drug overdose;
    - Severe violations of electrolyte blood composition.
    It should be understood that with chronic kidney disease, hemodialysis is started when renal failure no longer succumbs to conservative therapy and goes to the terminal stage. Hemodialysis in this situation is a method of maintenance therapy.

    Operating principle
    Apparatus for hemodialysis consists of three components: devices for blood supply, devices for preparation and supply of dialysate and dialyzer. The dialyser is the main part of the device. The most important functional element is a semipermeable membrane, which is made from natural materials based on cellulose, or from synthetic materials. The blood withdrawn from the patient's artery is passed through the dialyzer and is located on one side of the semipermeable membrane, while the solution, in its electrolyte composition similar to the circulating blood, accumulates on the other side of it. Water and unnecessary waste products of the body and toxins are filtered through this membrane. Proteins, blood cells, bacteria and substances with a molecular mass greater than 30000 through the membrane do not pass. Purified blood is then returned to the patient via the vein

    Procedure of hemodialysis
    Before starting the dialysis, the patient is examined by a doctor, measures blood pressure, pulse and temperature. The patient is then placed with vascular access and connected to a dialysis machine. During the procedure, the patient is constantly monitored. At the end of hemodialysis, an aseptic bandage is applied to the catheter placement area. The duration and frequency of sessions the doctor determines individually for each patient.

    Complications of hemodialysis
    - arterial hypotension;
    - Muscle cramps;
    - nausea and vomiting;
    - infectious diseases.
