Plasmapheresis is a modern, safe, painless and atraumatic method of blood purification.
Plasmapheresis is the separation of blood by the subsequent removal of a liquid fraction - plasma with accumulated slags, the return of cellular elements and the compensation of the volume obtained by plasma substitutes. It is included in the complex of treatment of diseases caused by impaired immunity, metabolism, intoxication in the case of ineffectiveness of generally accepted therapy.
Due to a violation of blood circulation, an increase in the concentration of toxins (toxins), antibodies and immune complexes in the blood, there is a natural "cleansing" and "blockade" of the protective systems: liver, kidneys, lungs, immune system. Toxic substances enter the lymphatic system, blood flow and circulate in large quantities in the blood (plasma).
Then they accumulate in the tissues, causing damage to organs. Plasmapheresis allows you to stop this process. Slags are first removed from the blood, and then from the tissues (drying effect). When redeeming the resulting plasma, blood dilution is achieved. Stagnation in the capillaries (small vessels) decreases, the flow of fluid from the tissues increases, which helps to improve blood circulation and tissue respiration in all organs.
The therapeutic effect of plasmapheresis includes immunostimulating, anti-inflammatory, and detoxifying effects due to:
- Elimination of circulating immune complexes, reduction of the concentration of antigens, antibodies;
- Removal of microbes, toxins, and end products of metabolism (slags) with plasma;
- Elimination of inflammatory factors-prostaglandins, thromboxans, lymphokins;
- Removal of procoagulants, cryoglobulins – substances that increase blood clotting;
- Restoring the sensitivity of cellular receptors to hormones, drugs - reducing the dose of drugs taken to achieve the desired effect;
- Normalization of blood microcirculation and rheology and restoration of impaired metabolism.
Plasmapheresis in our blood center < / span> is performed by two main methods:
1.discrete (manual) plasmapheresis is performed using a centrifuge and sterile disposable hemocontainers with preservatives. Blood is taken, the containers are centrifuged, then the plasma is removed and the blood cells are returned to the patient. In addition, saline solutions are poured, which compensate for the volume of the resulting plasma. In just one session of plasmapheresis, 300-600 ml of plasma is taken. This is the most affordable method, the duration of 1 session is 2-2.5 hours.
2.automatic (hardware) method is based on the separation of a continuous flow of blood taken in the separator of the Haemonetics PCS-2 (USA) apparatus, combined with automatic supply of anticoagulant, automatic plasma sampling and return of cells to the venous canal. Hardware plasmapheresis is most suitable for the patient and has its advantages:
small volume of replenishment of the system for blood
continuous cycle of blood collection, division, and cell return
low blood cell damage
ease of use, significant speed.
the duration of the session is 60-90 Min, the volume of extracted plasma is 600-1000 ML.
both methods are performed using a single-needle method (puncture of one peripheral vein) using only single-use Flow Systems.
the effect of plasmapheresis is manifested after the first session. The concentration of pathological products is significantly reduced, but after a few hours their content in the blood approaches the initial level. This indicates that substances located in the extracellular interstitial space or cells have entered the root canal. Subsequent sessions of plasmapheresis contribute to the destruction of these substances, which leads to a complete restoration of the entire internal environment, given that most of the harmful products are located outside the vascular space. For a stable positive effect,1-1.5 sessions are required, removing 3-6 volumes of circulating plasma from the total volume. The resulting plasma is effectively compensated by saline solutions.
thus, the inclusion of plasmapheresis in the complex of therapeutic measures contributes to a more favorable course of diseases that are particularly difficult to treat with medication, significantly improving the condition of patients and reducing their drug load.
