Features of laser therapy of venous trophic ulcers of the lower extremities in outpatient surgery

Abstract

Introduction. Trophic ulcers of venous etiology are a severe complication of chronic venous insufficiency of the lower extremities. At the same time, in most cases, ulcerative defects do not heal for a long time and are prone to recurrence, which leads to a significant deterioration in the quality of life of patients.Aim. To clarify the features of the effect of low-intensity laser radiation to determine the optimal conditions for conservative treatment of venous ulcerative defects.Materials and methods. A randomized prospective clinical trial was performed in which 126 patients with chronic venous insufficiency were monitored. During the conservative treatment of 44 patients of the comparison group, phlebotropic drugs, compression therapy, wound coverings and ointment dressings were used in the conservative treatment of trophic ulcers. In 82 patients of the main group, lowintensity laser radiation was used along with the methods described above.Results. Laser therapy in the complex treatment of venous trophic ulcers helps to reduce the number of microbial bodies vegetating on the surface of ulcerative defects, but does not significantly affect the sensitivity of microflora to antibacterial drugs. Low-intensity laser radiation certainly contributed to a significant and earlier increase in the number of neutrophils, monocytes and macrophages on the surface of trophic ulcers, as well as activation of phagocytic activity of cells.Conclusion. Low-intensity laser radiation improves the results of conservative treatment of venous trophic ulcers, does not adversely affect the sensitivity of the isolated microflora to antibiotics and does not have a “direct” bactericidal effect.
