ABSTRACT
Abstract. Having acquired a seasonal character, the new coronavirus infection COVID-19 has become an integral part of medical life. Most patients at this stage of the virus evolution have a mild to moderate form of the disease. However, a certain contingent still requires treatment in an infectious disease hospital, and some in intensive care units, since a distinctive feature of the new coronavirus infection COVID-19 is the need for respiratory support of varying degrees of invasiveness. Objective. To assess the dynamics of the PaO2/FiO2 (P/F) ratio in patients with a new coronavirus infection on mechanical ventilation depending on the timing of tracheostomy from the moment of orotracheal intubation. Patients and methods. A retrospective analysis of the dynamics of the PaO2/FiO2 (P/F) ratio was performed in 90 patients with a new coronavirus infection on a ventilator, depending on the timing of tracheostomy from the moment of orotracheal intubation with an infection on a ventilator from June 2021 to March 2022 at the Vidnovskaya District Clinical Hospital, reprofiled for medical care to patients with a new coronavirus infection. For the work, patient data were used for 5 days: 2 days before the tracheostomy was applied, on the day of surgery, and 2 days after the tracheostomy was applied. To ensure the relevance of the comparison of groups in this study, 2 control points were selected for comparative analysis: 1 day before surgery (T before) vs. 1 day after surgery (T1). Results. It was found that tracheostomy performed on days 1 and 3 from the moment of intubation of a patient with COVID-19 dynamically significantly increased the P/F ratio. Tracheostomy performed on days 7–14 from the moment of intubation of a patient with COVID-19 did not dynamically affect the P/F ratio. Taking into account the heterogeneity of indicators in the group where the operation was performed on the 3rd day from the moment of orotracheal intubation, the question of shifting the timing of the tracheostomy to an earlier one —1 day—becomes relevant. This issue requires more in-depth study.
