Abstract

Use in surgery, The goal is to reduce the treatment time by accelerating the process of epithelization of the surface of trophic ulcers. The essence of the method acts on the surface of the trophic ulcer with an incoherent source of red light obtained from a conventional incandescent lamp by using a broadband red filter with a spectral composition of 600-850 nm and a power density of 7.5-20 mW / cm2 for 3-20 minutes daily, the number of sessions 10-25. Positive effect: accelerates the process of epithelization of the surface of trophic ulcers by 6 times (0.71 cm2 / day versus 0.11 CM2 / cyij. Which shortens the treatment period by 4-6 days.

Description

The invention relates to medicine, namely to phototherapy, and can be used to treat trophic ulcers.

A known method of treating trophic ulcers and long-term healing wounds using optical quantum generators (lasers) in connection with a violation of tissue trophism. The trophic ulcer is irradiated with a helium-neon laser with a wavelength of 632.8 nm and a power density of up to 2 mW / cm for 3 minutes. The average rate of epithelization of the surface of trophic links when using a helium-neon laser is 0.11 ± 0.07 cm2 / day.

The disadvantage of this method is associated with the use of expensive laser equipment, as well as with insufficient epithelization rate.

The aim of the invention is to reduce the treatment time.

The goal is achieved in that the surface of the trophic ulcer is exposed to incoherent red light with a spectral composition of 600-850 nm with a power density of 7.5-20 mW / cm2 for 3-20 minutes daily, with a number of sessions of 10-25.

The method is carried out as follows.

The surface of the trophic ulcer is exposed to an incoherent source of red light obtained from a conventional incandescent lamp by using a broadband red filter with a spectral composition of 600-850 nm and a power density of 7.5-20 mW / cm2 for 3-20

PRI me R 1. Sick P., 62 years. Diagnosis: postthrombophlebitis syndrome, trophic ulcer of the left leg. For 20 years, post-thrombophlebitic syndrome, since 1975 - trophic ulcer of the left tibia, about which it was repeatedly treated in hospitals of the city for 2-3 months with varying success. Recently, it has been constantly applying hormonal ointments to the surface of the ulcer. Upon admission, the trophic ulcer of the left tibia with an area of 16.1 cm2 was revealed. The patient conducted 25 daily sessions of irradiating the surface of the trophic ulcer with incoherent red light with a spectral composition of 600-850 nm with a power density of 7.5 mW / cm2 at an exposure time of 20 min. After the completed course of phototherapy, the surface of the trophic ulcer decreased to 0.5 cm2, after which Linton's surgery was performed. In the postoperative period, 5 sessions of irradiation of the surface of the trophic ulcer with a power density of 12.6 mW / cm2 with an exposure of 10 minutes were performed. After that, the complete epithelization of the surface of the trophic ulcer was noted. The ulcer healing rate is 0.62 cm2 / day. The patient spent 34 days in the hospital.

PRI me R 2. Sick K., 71 years. Diagnosis: postthrombophlebitis syndrome, trophic ulcer of the left leg. The area of the name is 6.6 cm2. Postthrombophlebitis syndrome 10 years. Left leg ulcer - 2 years. The surface of the trophic ulcer was irradiated with a low-energy source of incoherent red light with an exposure of 3 minutes at a power density of 20 mW / cm2. Completed 12 daily sessions

owls After that, the complete epithelization of the surface of the trophic ulcer was noted. The ulcer healing rate is 0.55 cm2 / day.

PRI me R 3. Patient G., 67 years old. Diagnosis: postthrombophlebitis syndrome, trophic ulcer of the lower posterior surface of the right lower leg with an area of 9 cm2. In 1970, the patient underwent Linton surgery. In subsequent years, chronic venous insufficiency developed. 3 months before hospitalization, a trophic ulcer appeared on the right lower leg.

Outpatient treatment was performed using occlusive zinc-gelatin dressings with short-term success. Daily phototherapy of the surface of the trophic ulcer with incoherent red light with a power density of 14.6 mW / cm2 with an exposure of 10 minutes was carried out. The number of completed sessions is 10. After phototherapy, the complete epithelization of the surface of the trophic ulcer was noted. The ulcer healing rate is 0.9 cm2 / day. The patient spent 18 days in the hospital.

The proposed method allows to accelerate the process of nasal surface sterilization of trophic links - 6 times (0.71 versus 0.11 cm / day), which allows to reduce the treatment time for patients by 4-6 (days,

Claims (1)

The claims A method for treating trophic ulcers by exposing its surface to a red light source, characterized in that, in order to shorten the treatment time due to acceleration of filamentation, the effect is carried out by an incoherent source with a spectral composition of 600-85Q nm with a power density of 7.5-20 mW / cm2 for 3/20 minutes daily, the number of sessions 10-25.
