This invention relates to medicine, namely to surgery.

The aim of the invention is to reduce the treatment time due to monochromatic irradiation with a helium-neon laser and simultaneous oxygenation of the blood outside the body.

The method is carried out as follows.

Autohemotransfusion wire: in the amount of 200 ml of blood, oxygenates it and affects the oxygenated blood flow by monochromatic laser radiation. The radiation power is 20 mW, the wavelength is 632.8 nm with an irradiation power density of 1 mW and a laser dose of 7.5 j in the amount of 3-4 sessions per treatment course.

Example. Sick V., 40 years old, diagnosis: subaponeurotic phlegmon of the anterior abdominal wall sepsis. Comparison of average gravity. The required dose of irradiation is 7.5 J. The intensity of irradiation of the cuvette with laser radiation of the laser 12-1, created in the device for implementing the method, mW / cm. The blood flow rate is 12.5 ml / min 0.2 MP / s. The surface area of the cell subjected to laser irradiation is S 7.5 cm. Based on the formula

where P is the radiation dose needed; S is the surface area of the cell that is exposed to laser irradiation; I - irradiance intensity

one . By a ratio of 155 of the calculated amount of blood, it is determined that 50 ml of a glucose-citrate solution (glugicir) is needed to stabilize 200 ml of blood.

200 ml of blood is expelled (by puncture of the peripheral vein of the forearm) into a standard vial for blood collection from 50 ml of glugicir. A bottle of blood is placed on the stand of the device. After supplying oxygen through the tube in 2 l / min mode, the vial is connected to the device using a tube. During the flow of blood from the vial into the container through the cuvette, it receives an irradiation dose P equal to

S-I- (A + A4) .K

7.6 (j).

Thus, the chosen value of the intensity of irradiation and the rate of flow of oxygenated stabilized blood in combination with a certain volume (A) provides the required dose of radiation. After three sessions of irradiation using the above method with the parameters chosen in the same way, the patient was accompanied by a cleansing wounds, the early occurrence of granulation tissue, an increase in the indices of nonspecific resistance of the organism. Immediately after the introduction of irradiated blood by intravenous drip transfusion, there was a sensation of heat in the limbs, accompanied by the appearance of cheerfulness. Extracorporeal irradiation before and after the operation by alternating the procedure every other day.

The use of this method led to a decrease in bed-days on average 10-12.
