Aim. To evaluate the effectiveness of using ozonated solutions combined with decamethoxin solution in the treatment of purulent wounds.Methods. 101 patients with purulent wounds were under observation. In the treatment of all patients, the first stage was surgical debridement, which removes exudate and non-viable tissue. Also the conditions for wound drainage and good drainage of wound exudate were created, and then the treatment of wounds under a bandage was performed. In the main group (51 people) in addition to the basic treatment ozonated 0.9% sodium chloride solution with a concentration of ozone 8-10 μg/mL and 0.02% decamethoxin solution were used. The general condition of patients and the wound condition were evaluated over time.Results. The duration of fever and pain syndrome did not differ in the groups. A statistically significant difference between groups in the terms of symptoms disappearance and wounds healing was found, indicating the advantages of using the decamethoxin solution in combination with ozonated 0.9% sodium chloride solution in treatment of purulent wounds. The length of stay in hospital statistically significantly decreased compared to the control group. Positive dynamics was observed on the wounds cytology: starting from 3 days of treatment in the main group neutrophil count decreased, number of lymphocytes and polyblasts increased. With the increase in terms from the beginning of the treatment, there was even greater reduction in the number of neutrophils, the increase in the number of lymphocytes and the appearance of macrophages and fibroblasts.Conclusion. The study results demonstrated the benefits of using combination of ozonated solutions with decametoxine solution in the treatment of purulent wounds; method is available to any surgical wards and outpatient clinics.
