Cryogenesis (cryoprecipitation) is a method of treatment in which pathological substances are selectively removed from the blood plasma, but all the necessary structures in the human body are preserved. This method consists of cooling the plasma. Purification of the plasma taken from the patient's blood is carried out with the help of a separator, which has special filtration columns - they just eliminate pathological substances.
Cryopathology is faced with the task of stopping or significantly reducing the symptoms of the disease, the risk of developing heart attack and stroke, to achieve confident remission and extend its period in chronic diseases, to reduce the intensity of acceptable complications.
Cryopheresis helps to normalize or improve the data of a number of studies (functional vascular examination, Holter monitoring, VEM, ultrasound, echoCG, ECG), normalize blood cholesterol, reduce atherogenicity, blood clotting, susceptibility to the formation of blood clots and blood viscosity.
The procedure restores blood circulation and elasticity of the walls of blood vessels, reduces atherosclerotic plaques and deposits, improves blood supply to the internal organs (sleep, memory, concentration, mood, potency in men, performance and endurance).
Cryopheresis will also help increase drug susceptibility. In addition, this technique is used to prevent and stop the destruction of the patient’s ability to work.
Indications for the procedure
There are cryopheresis of a short and long-term course of treatment, which includes no more than 5-7 procedures within 2-4 days. This method of treatment is performed from 6 to 18 months - during this period of therapy, the plasma is processed 2-3 times.
A long-term course of cryophoresis is prescribed for chronic ailments of the body, such as ischemia of the heart, atherosclerosis, coronary bypass, myocardial infarction. First, a course treatment is performed, then there is an increase in the transition period between the execution of procedures and the amount of plasma taken. In addition to this technique, other procedures can also be prescribed, it is used independently for skin and autoimmune diseases, hepatitis C, and atherosclerotic vascular disease.
This method helps to obtain a confident remission in chronically ill patients, an enormous decrease in the signs of the disease, normalization of the blood supply and rehabilitation of the vessel walls, and a reduction in the risk of abrupt cardiac positions.
Cryotherapy has only positive reviews from patients today. After treatment, serious complications were not observed, but there is still the possibility of the appearance
- pressure surges and weakness.
Although the cryophoresis procedure itself is quite safe and bears only a positive result, it still has a number of contraindications, like any treatment. These contraindications are divided into 2 types.
Absolute (strictly prohibited): the presence of a source of bleeding or a high risk of its renewal, the presence of a closed purulent source, the manifestation of an allergy to any components of a treatment session.
Relative (when the procedure is resolved under closer supervision of the doctor in the event that without it the course of treatment itself is impossible):
- severe cardiovascular ailments;
- hypotension, anemia, hypoproteinemia;
- exacerbation of phlebitis of peripheral veins;
- lack of venous passage;
- withdrawal anxiety;
- critical stage of infectious diseases and inflammations;
- hemostasis disorders;
- risk of premature birth or miscarriage in the early stages of pregnancy.
The process of cryopheresis
The patient is seated in a chair and with the help of certain medical equipment the necessary amount of plasma is collected through a vein, and so he sits until the end of the process.
The main thing - all this time not to bend the arm in which the needle is installed, and in the process you can read books, talk on the phone, watch TV, listen to music, work on a laptop, etc., and even drink tea, coffee and other non-alcoholic the drinks.
After the end of the session, a bandage is applied to the place where the needle is inserted, with which the person leaves the hospital. This bandage must be kept for at least six hours.
Immediately after taking the plasma, it is given for processing. A heparin solution is added to the plasma — a precipitate forms under its influence. Sterile packed plasma is put in a freezer at -2 °.
Before the next session, the plasma is transferred to the refrigerator for defrosting, and before starting therapy it is centrifuged to obtain a cryoprecipitate precipitate. In sterile packages through hemosorbent pass over sedimentary plasma. Immediately before entering the plasma to the patient, it is heated in a water bath to 37 °.
When carrying out this method of treatment of serious complications is not observed, however, there are a number of few points that should be familiar to the patient.
Firstly, it may be a small bleeding in the area of the puncture of the vein, it must be quickly stopped by applying a tight bandage. Secondly, the patient may complain of short-term dizziness, which are directly related to irregular blood pressure during the session.
Thirdly, the patient may feel a general insignificant weakness in the period between treatments, although it does not manifest itself in every person and does not in the least interfere with the normal way of life of the patient.
Fourthly, the patient may be allergic to those drugs that are used during the procedure itself.
Even less often, such sensations as temporary headaches, mild nausea, numbness or tingling in the lips, nose, fingers, as well as muscle tissue twitching are observed. It is important to remember that at the very beginning of the procedure, the patient may aggravate the disease itself, but this is only in the early stages of therapy.
If a person has more severe forms of the disease, then the complications may be more acute. Especially it concerns those cases when the patient was already in a serious condition and, probably, stayed in the conditions of resuscitation therapy.
The process of preparing the patient for the procedure
I would like to note that cryogenesis is carried out only if the patient has a laboratory test to detect HIV, hepatitis B and hepatitis C.
Also, the patient must be familiar with all the documents that describe the details of the procedure, fill out and sign a voluntary consent to medical or diagnostic manipulation, as well as to a medical invasion.
The patient does not need specific training to perform the cryopheresis procedure. Only the attending doctor may, immediately before the session itself, prescribe blood for specific laboratory tests.
Therefore, it is better for the patient to come to the clinic with an empty stomach in order to avoid embarrassment. After taking blood for the laboratory, a person can calmly have breakfast, sitting in a chair right during the session.
