Uso de um gerador de ozônio de volume controlado na adiposidade localizada abdominal: ensaio clínico controlado e randomizado

Abstract

Ozone therapy has been suggested in clinical practice as a promising and adjuvant therapy in the minimally invasive treatment of localized adiposity; however, evidence is limited for its recommendations. Thus, the aim of the study was to evaluate the safety and efficacy of a controlled-volume ozone generator at different dosages in localized abdominal adiposity. To achieve this objective, a single-center randomized controlled clinical trial was conducted. Female participants were recruited and 110 were randomized into 4 groups: Sham Group (GS): participants received treatment with the ozone equipment turned off; Intervention Groups: participants received ozone treatment at doses of 20 (G20), 30 (G30), and 40 g/ml (G40). The interventions were performed at 24 pre-established points in the abdominal region, twice a week for a period of 4 weeks, totaling 8 sessions. The initial assessment (A1) and reassessment [15 (A2) and 30 (A3) days after the last session] were performed through anthropometric analyses, bioimpedance, abdominal circumference, adipometry, global aesthetics (GAIS), adipose tissue thickness through diagnostic ultrasound, recording of patient satisfaction assessment (Linkert) and adverse effects. The main results show that groups G20, G30 and G40 presented a reduction in abdominal circumference in the periods of 15 and 30 days after treatment, lower GAIS score and improvement in the treatment satisfaction score in both periods evaluated. However, G40 presented lower adipose tissue thickness in both experimental periods. No serious adverse effects were reported. Thus, it can be suggested that the controlled volume ozone generator used in the present study proved to be a safe and potentially promising modality in the treatment of localized adiposity, with emphasis on the dose of 40 ug/ml.
