Kidney failure, acute kidney injury, and chronic diseases cause the organ to malfunction and the inability to perform its basic functions. Having established the diagnosis, the doctor prescribes dialysis, a method of removing waste products, fluids, and toxins from the body. To perform the procedure, an «artificial kidney» — a dialyzer — is used.

How to choose a dialyzer

Before buying a dialyzer, it is important to evaluate the properties of the filter and active membrane. The key characteristics of the products that you should pay attention to when choosing:

Membrane material: cellulose, semi-synthetic, synthetic. Difference in permeability, biocompatibility, thrombogenicity, individual reaction of the body. Modern models of dialyzers have a synthetic membrane.
The volume of blood filling the circuit — up to 100 ml, more than 100 ml. The parameter is strictly controlled depending on age and the degree of hemodynamic disturbance. Dialyzers of smaller volume are more in demand, as the reduction of filling while maintaining, increasing the active area of the membrane provides high efficiency of the procedure.
The ultrafiltration coefficient expresses the permeability of membranes. They are divided into low-flow, medium-flow and high-flow.
The area of the filtering surface: up to 0.5 and more than 0.5 m². The indicator determines the quality, speed of blood purification. Thanks to the use of new materials, filtration is improved even with a small membrane area.
Sterilization of the dialyzer: by gas, gamma irradiation, steam in an autoclave. The safety of the system depends on the treatment.
Configuration — plate and capillary.

Portable dialyzers of plate type provide low resistance to blood flow, have a small volume inside the system, predictable filtration process. Capillary models are effective, safe, maintain stability during purification, equipped with a membrane made of biologically inert materials.

Features of dialysis

During hemodialysis, it is necessary to purify a large volume of blood from harmful substances. To do this, the doctor surgically forms a special vascular access — arteriovenous fistula or prosthesis. It takes 2-3 weeks for the tissues to recover. After that, the AV fistula is ready to function in full. Hemodialysis does not cause discomfort to the patient. The standard regimen of the procedure is three sessions per week for 4-5 hours. The specialist adjusts the frequency and duration. Liquid, short dialysis can cause a deterioration in health and general condition of the body. As a rule, the procedures are performed in a nephrology or dialysis center under the strict supervision of medical staff.
