[The role of systemic ozone therapy in the rehabilitation of patients after COVID-19]. / Rol' sistemnoi ozonoterapii v reabilitatsii patsientov, perenesshikh COVID-19.

OBJECTIVE: To evaluate the effectiveness and safety of ozone therapy in rehabilitation of patients with previous COVID-19. MATERIAL AND METHODS: A randomized controlled clinical trial included 51 patients aged 29 - 78 years with SARS-CoV-2 pneumonia (J12.8). Patients were divided into 3 comparable groups depending on the complex of rehabilitation. In the first (control) group (n=17), a 10-day course included daily breathing exercises and physiotherapy for the lungs (drug electrophoresis and low-frequency magnetotherapy). In the second (main) group (n=18), rehabilitation was combined with daily intravenous infusions of ozonized saline with ozone concentration of 2.0 mg/l within 5 days with subsequent standard rehabilitation. In the third group (n=16), patients received 5 ozone therapy procedures every other day. To determine the effectiveness and safety of systemic ozone therapy in rehabilitation of patients with previous COVID-19, we analyzed oxygen saturation, laboratory data (D-dimer and C-reactive protein), need for oxygen support before and after rehabilitation course. Complaints and quality of life throughout the rehabilitation program were assessed using the EQ-5D questionnaire. RESULTS: All patients had positive changes of all parameters. There were no adverse reactions throughout the rehabilitation program and 2 months later. We observed higher effectiveness of rehabilitation with systemic ozone therapy. Moreover, daily ozone therapy had a better effect on laboratory parameters compared to ozone therapy every other day. CONCLUSION: Ozone therapy is safe and effective in complex rehabilitation of patients with previous COVID-19. Further studies of large samples are needed to determine indications and appropriate criteria for this rehabilitation program.

[Influence of therapeutic exercises and hardware massage in electrostatic field on lung damage in patients with novel coronavirus pneumonia]. / Otsenka vliyaniya lechebnoi gimnastiki i apparatnogo massazha v elektrostaticheskom pole na stepen' porazheniya legkikh u patsientov s pnevmoniei pri novoi koronavirusnoi infektsii.

OBJECTIVE: To analyze the efficacy and safety of therapeutic exercises and chest hardware massage in electrostatic field in patients with COVID-associated viral pneumonia. MATERIAL AND METHODS: We retrospectively analyzed 1551 patients admitted to the Clinical Hospital No. 1 (MEDSI Group JSC) with COVID-associated pneumonia between April 01, 2020 and June 15, 2021 (ICD-10 U07.1 and U07.2). Considering inclusion and exclusion criteria, we enrolled 153 patients. All patients were divided into comparable groups and subgroups depending on the methods of rehabilitation treatment and CT stage of viral pneumonia. Lung damage was assessed semi-automatically using Philips Portal v11 COPD software. Rehabilitation measures included therapeutic exercises and chest hardware massage in electrostatic field. therapeutic exercises. RESULTS: Therapeutic exercises significantly reduced severity of lung damage in patients with viral pneumonia CT-2 and no oxygen support (from 28.05% [28; 29.5] at admission to 15.3% [14.2; 19.3] at discharge). It was not observed in patients without rehabilitation treatment and in patients undergoing therapeutic exercises and massage in electrostatic field. CONCLUSION: Therapeutic exercises in patients with COVID-19 and baseline lung damage > 25% and < 50% (CT-2 stage) significantly reduce severity of lung damage at discharge compared to the control group.
