Description

 The invention relates to surgery and can be used to treat burn wounds.

There is a method of treating burn wounds with a helium-neon laser according to the scheme, including the initial exposure to a power stream of 4 mW / cm ² for 60 s for 2 procedures, and then a power stream of 0.5 mW / cm ² for 30 s to complete healing [5] .

 Despite the rapid healing of wounds when exposed to a laser, the latter can adversely affect human health and has negative side effects.

 Therefore, to reduce side effects, it is advisable to use radiation sources that are safer for human health. In particular, in the practice of treating burn wounds, broadband sources of red light emitting spectra that are similar in shape and maximum position to the absorption spectra of biologically significant molecules have become widespread [4].

Closest to the invention in technical essence and the achieved result is a method of treating soft tissue wounds by exposing a red monochromatized incoherent luminescent light flux with a wavelength of 600-900 Nm to rectangular pulses with a pulse repetition rate of 40-41 Hz, a duration of 12-13 ms, density power flow 5-10 mW / cm ² for 12-20 minutes for 6 days [1].

 However, the known method is not effective enough in the treatment of burn wounds III A-B degree.

 The objective of the invention is to expand the technical capabilities of the method and increase the effectiveness of the treatment of wounds for burns III AB degree with a decrease in post-treatment side effects.

The problem is solved in that in the known method of treating skin wounds by exposure to red monochromatized incoherent luminescent (KMNL) light with a wavelength of 600-690 Nm, rectangular pulses with a pulse repetition rate of 40-41 Hz, a duration of 12-13 ms at a flux density power of 5-10 mW / cm ² for 15-20 min daily, in accordance with the invention, exposure to red monochromatized incoherent luminescent light is carried out until the wound is completely cleansed of necrotic tissue and the appearance of a granule cation, after which the wound is exposed to a helium-neon laser with a wavelength of 632.8 Nm at a power flux density of not more than 0.5 mW / cm ² for no more than 30 s until the wound is completely healed.

The total number of procedures for treating a wound with KNNL-light is determined in each case individually by complete cleansing of the wound and the appearance of granulations on it. Exposure to the wound just before the start of granulation is an important essential characteristic of the method, since it affects the final result of the treatment of a burn wound of the III-B degree. The cessation of treatment with KNNL-light until the formation of granulations in the wound leads to an increase in the healing time of wounds. The use of CMLN light after the formation of granulations in the wound is not effective. A faster healing of the wound is facilitated by the effect on it, after the formation of granulations in the wound, with a helium-neon laser. Laser therapy is carried out with a length of 632.8 Nm, with a power flux density of not more than 0.5 mW / cm ² for no more than 30 s. A longer exposure to a stream of higher power density is impractical, because this increases the likelihood of side effects. At lower rates of the regime, the effect of laser therapy is not effective.

The sources of scientific, technical and patent literature did not reveal information on the treatment of burn wounds of the III-B degree by successive exposure to KNNL light until the wound was completely cleaned and granulations appeared, followed by exposure to a 632.8 Nm helium-neon laser and power flux density not more than 0.5 mW / cm ² for no more than 30 s until it is completely healed. Therefore, the presented set of essential features of a method for treating soft tissue wounds is new and meets the criterion of "inventive step".

The proposed method was tested in an experiment on white outbred males after a 10-day quarantine period weighing 150-180 g. Burn wounds were applied under ether anesthesia, after preliminary preparation of the surgical field by contacting the skin of the animal in the back area on a 5x4 area heated to 100 ^o C a metal plate of a special device [3].

 The experiment was carried out in 8 groups of 20 animals, in which the treatment of burn wounds was carried out using CMLN light, a helium-neon laser, and a combined method. The therapy with KNNL-light was carried out using a “polychrome” apparatus [4], and the therapy with a helium-neon laser was performed using OKG-13 [5]. Monitoring of wound healing was carried out visually and planimetrically [2].

 A visual assessment was used to determine the timing of the start of cleansing a burn wound from necrotic tissue, the timing of the appearance of granulations, the onset of epithelization, complete rejection of the scab and complete healing of the wound.

 Planimetric control was carried out by measuring the area of the wound, the contour of which was obtained by applying a sterile cellophane film, fixing the contours of the wound and transferring them to graph paper with a further calculation of the area [2].

 The experimental results are presented in table. 1, 2, 3, 4.

 As can be seen from the tabular data, the dynamics of healing of burn wounds III AB degree is better expressed in groups of animals, where the treatment was carried out by the proposed method. In general, the healing period with III degree burns, with combined exposure, was 6 days less than in the control, 4 days less than in group 2, where monochromatized light was used, and 2 days less than in group 3, where only laser therapy was used. In animals with burns of degree III B, the healing time was accordingly reduced with combined exposure by 14 days compared with the control, by 5 days compared with group 2 / monochromatic incoherent luminescent light /, and 3 days less than in group 3, where it was used only laser therapy.
