Plasmapheresis

Plasmapheresis

With the development of medicine, new methods appear to improve the patient's health. Today it is available in many wellness centers under the simple name "blood purification".

Doctors promise with the help of plasmapheresis to improve the patient's health, rid him of toxins. The word itself is compound, comes from the Greek "plasma" and "pheresis". If the first is more understandable and means one of the main components of blood, then the second is formed from the root of the word "remove".

Plasma supplies the internal organs with nutrients, but sometimes contains an excess volume of what leads to unpleasant processes. That is why a method was created for removing plasma from the body, with the aim of purifying it. But how effective and safe is this therapy? Many see it through the prism of myths, which will be discussed below.

Plasmapheresis is the purification of blood from toxins. Doctors often come across patients who ask to cleanse their blood from toxins. This is actually a medical procedure called plasmapheresis. And the concept of "slags" does not exist in healthcare, so to clean the blood from them is quackery. It is also impossible to talk about by-products of vital activity, since most of the substances in the blood are natural. The body usually utilizes them through its own mechanisms. The procedure simply reduces the concentration of certain substances in the blood, but does not interfere with their further formation, does not eliminate the root cause.

Plasmapheresis results cannot be seen. The technique itself is based on passing the liquid part of the patient's blood, plasma, through a filter membrane. It has holes of a certain diameter. Large protein molecules with toxic substances or inflammatory elements do not pass through the filter. Patients are usually shown the membrane before and after the procedure so that they can see the result of plasma processing with their own eyes.

Plasmapheresis is a simple procedure. A special technique is used to carry out this simple procedure. An example would be Gemos-PF, which is also used by the Ministry of Emergencies when providing emergency assistance to victims. The patient lies down on a couch and a plastic catheter is inserted into his vein to draw blood. Carefulness and professionalism are required from a specialist. Taking this into account, as well as complex equipment, the procedure cannot be called simple.

Plasmapheresis can be done anywhere it is advertised. There are two basic types of this procedure - membrane and cascade. The second is carried out in specialized centers, it is fundamentally not suitable for patients with cancer. But the method of membrane plasmapheresis is safer and less traumatic. In the case of ordering donor fresh frozen plasma, the procedure is carried out as planned. It is carried out on specialized devices in the treatment room for blood transfusion.

During the procedure, only one vein is involved. There are different methods of performing the procedure. In one case, indeed, only a single vein is needed, while in the other, a peripheral and central vein is needed.

All human blood is pumped through the apparatus. After installing the catheter, blood begins to flow through the device, but not all, but only that which is taken. Each person has his own blood volume, which is why for each session the doctor calculates how much fluid will be pumped through. The blood test, the patient's body weight, and his height are taken into account. Even a computer program has been created to facilitate calculations.

The procedure can take an entire day. In fact, a plasmapheresis session lasts about an hour. All this time, the patient's condition is monitored, his pulse is measured, breathing is monitored, and how the blood is saturated with oxygen is monitored. A person is watched not only by a specialist, but also by equipment.

To carry out plasmapheresis, you need to go to the hospital. This procedure can be done on an outpatient basis, but it is not so simple that it can be done almost at lunchtime. Still, do not confuse blood purification with an injection. People tolerate plasmapheresis in different ways, which is why it takes some time after it is still under medical supervision. Usually half an hour is enough. If the vital signs are stable, the patient can return to his normal life until the next session.

Plasmapheresis is not safe. Rumors have spread that people can die from this procedure. First of all, it should be emphasized that disposable medical instruments are used. Doctors in front of their patients demonstrate how to open the kits. It should be understood that plasmapheresis is not a conveyor belt, when the doctor connects the device and leaves somewhere. During the procedure, the specialist constantly monitors the patient's condition, communicates with him. And at the end of the session, the person is under observation for some time. And no third-party medicines are used during the procedure. Unless the lines through which the blood flows are treated with saline so that the liquid does not coagulate. And if the patient uses hormonal drugs excessively, then they are included in the protein components of the plasma, settling on the filters. Thus, excess hormones are removed from the blood of a person, with which he was overfed.

Plasmapheresis is unpleasant. The whole process is part of the physiology of the heart, there can be no unpleasant sensations from this. In a state of systole, blood is pushed out of the heart, and with diastole and relaxation, it returns back. Plasmapheresis does not affect normal blood flow in any way.

For plasmapheresis, donor plasma is used. Many patients are afraid that they will receive plasma from a stranger. In fact, usually no donor product is used. We can talk about cascade plasmapheresis, when 400-800 ml of plasma is taken and blood substitutes are supplied to the body instead. But this is not the best practice.

Membrane plasmapheresis has no contraindications. There is one absolute contraindication for such a procedure - a stomach ulcer with bleeding. The unstable operation of the blood coagulation system is a relative contraindication. Doctors do not recommend carrying out the procedure to a person who has a poorly developed peripheral venous network. It is difficult for a specialist to find a vein, so it's best not to risk it.

Plasmapheresis is a universal procedure that helps with any disease. You can find quite a few ads that advertise plasmapheresis as a universal procedure. Experts urge all city dwellers to pass through it, because it will help fight stress and reduce the consequences of a bad environment. Advertising promises rejuvenation of the body. But this is not the case. It should be understood that the procedure is not cosmetic, but purely medical. Plasmapheresis complements the mainstream treatment. Only a doctor can prescribe such treatment based on indications. It makes no sense to do it just like that, for the sake of "rejuvenation" and "cleaning from toxins".

One session is enough to improve the skin condition. The doctor calculates the individually required number of sessions. The nature of the disease, its duration, the patient's well-being are taken into account. On average, for skin diseases, improvement will occur after 5-7 procedures. But with allergic dermatitis, the result may become obvious after a couple of sessions.

Immunity worsens due to plasmapheresis. This judgment is based on the opinion that with the release of blood, immunity also goes away. In fact, plasmapheresis has the opposite effect. Immunity decreases briefly and immediately increases due to blood cleansing.

Taking blood can lead to malfunctioning of vital organs. During plasmapheresis, blood is taken in such proportions so as not to damage the activity of the body. The level and quality of blood flow is provided with saline until the purified fluid returns.

Plasmapheresis has no complications. Complications of plasmapheresis still occur. This can be pulmonary edema, allergic reactions, up to anaphylactic shock, blood clotting disorders and related bleeding, infection with hepatitis viruses, lowering blood pressure and phlebitis. Complications can lead to death, but this happens only in one case in 5000.
