Plasmapheresis



With the development of medicine, new methods are emerging that allow improving the patient’s health. One of them is plasmapheresis. Only ten years ago this procedure was considered medical, it was prescribed only for certain diseases. Today it is available in many health centers under the simple name of “blood purification”.

Doctors promise with the help of plasmapheresis to heal the patient, to save him from the slags. The word itself is compound, comes from the Greek “plasma” and “pheresis”. If the former is more understandable and means one of the main components of the blood, the second is formed from the root of the word “remove”.

Plasma supplies the internal organs with nutrients, but it sometimes contains in excess volume what leads to the appearance of unpleasant processes. That’s why the method of plasma withdrawal from the body was created, with the purpose of its purification. But how much is this therapy effective and safe? Many see it through the prism of myths, which will be discussed below.

Plasmapheresis

Plasmapheresis is the purification of blood from toxins.

Doctors often encounter patients who ask them to clear their blood of toxins. In fact, there is a medical procedure called plasmapheresis. Yes, and the concept of “slag” in health care does not exist, so that to cleanse the blood from them is charlatanry. You can not talk about the by-products of life, since most of the substances in the blood are natural. The organism usually uses them due to its 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 underlying cause.

The results of plasmapheresis can not be seen.

The technique itself is based on the transmission of the liquid part of the patient’s blood, plasma, through the membrane filter. It has holes of a certain diameter. Large protein molecules with toxic substances or inflammatory elements through the filter do not pass. Patients are usually shown a membrane before and after the procedure so that you can see the result of plasma treatment with your own eyes.

Plasmapheresis is a simple procedure.

For this simple procedure, a special technique is used. An example may be the Gemos-PF, which is used by the Ministry of Emergency Situations in providing emergency assistance to the victims. The patient lies on the couch, a plastic blood catheter is placed in his vein. From the expert care and professionalism is required. With this in mind, as well as complex equipment, the procedure is not easy to call.

Plasmapheresis can be carried out anywhere where it is advertised.

There are two principal types of this procedure – membrane and cascade. The second is carried out in specialized centers, patients with oncological diseases, it basically does not fit. But the method of membrane plasmapheresis is safer and less traumatic. In the case of ordering a donor fresh frozen plasma, the procedure takes place in a planned manner. It is performed on specialized apparatuses in the procedural room for blood transfusion.

Only one vein is used during the procedure.

There are different procedures for implementing the procedure. In one case, really, only a single vein is needed, and in the other one you need a peripheral and central vein.

Through the apparatus all the human blood is run.

After the catheter is inserted through the device, blood begins to run, 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 liquid will be run. The analysis of blood, body weight of the patient, its growth is taken into account. To facilitate calculations, even a computer program was created.

The procedure can take a whole day.

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

For plasmapheresis it is necessary to go to the hospital.

This procedure can also be done on an outpatient basis, but it is not so simple that it can be done almost at lunchtime. Still, you should not confuse the purification of blood with a prick. People differently tolerate plasmapheresis, which is why it takes some time after the procedure to remain under the supervision of a doctor. Usually half an hour is enough. In the case of the stability of indicators of life, the patient can return to his normal life until the next session.

Plasmapheresis

Plasmapheresis is unsafe.

Rumors spread that people may die from this procedure. First of all, it should be emphasized that one-time medical instruments are used. Doctors in their patients demonstrate how to open kits. It should be understood that plasmapheresis is not a conveyor belt, when the doctor connects the device and goes somewhere. During the procedure, the specialist constantly monitors the patient’s condition, communicates with him. And at the end of the session for a while a person is under observation. And no third-party medication is used during the procedure. Is that the mains, through which blood flows, processed saline so that the liquid does not fold. And if the patient over-uses hormonal drugs, they are included in the protein components of the plasma, settling on the filters. Thus, extra hormones are removed from the human blood, which he was overfed.

Plasmapheresis causes unpleasant sensations.

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

Plasmapheresis uses donor plasma.

Many patients are afraid that they will be infused with an external person’s plasma. In fact, usually the donor product is not used. This can be a 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 method.

Membrane plasmapheresis has no contraindications.

There is one absolute contraindication for such a procedure – a stomach ulcer with bleeding. Unstable blood coagulation system is contraindicated. Doctors do not recommend the procedure for a person who has a poorly developed peripheral venous network. It is difficult for a specialist to find a vein, so it’s better not to take risks.

Plasmapheresis is a universal procedure that helps with any illnesses.

You can meet a lot of ads that advertise plasmapheresis, as a universal procedure. Experts urge to pass through it all residents of cities, because it will help to deal with stress and reduce the consequences of bad ecology. Advertising promises rejuvenation of the body. But this is not so. It is necessary to understand that the procedure is not cosmetic, but purely medical. Plasmapheresis supplements the basic treatment. To appoint such treatment only the doctor on the basis of indications can. Do it just like that, for the sake of “rejuvenation” and “cleaning up from slags,” there is no sense.

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, skin diseases will improve after 5-7 procedures. But with allergic dermatitis the result can become obvious after a couple of sessions.

Because of plasmapheresis, immunity worsens.

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 for a short time and immediately increases due to the purification of blood.

Plasmapheresis

Blood sampling can lead to malfunctioning of vital organs.

With plasmapheresis, blood is taken in such proportions so as not to damage the body’s activity.The level and quality of blood flow is provided by physiological saline until the purified liquid is returned.

Plasmapheresis has no complications.

Complications of plasmapheresis still occur. It can be pulmonary edema, allergic reactions, up to anaphylactic shock, bleeding 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 out of 5000.
