Обеспечение искусственной однолегочной вентиляции при посттрахеостомическом стенозе трахеи для торакоскопической пластики правого купола диафрагмы

The article is devoted to the consideration of a clinical case of providing artifcial one-lung ventilation for performing thoracoscopic plastic of the right dome of the diaphragm in a patient with grade 3 posttracheostomy cicatricial tracheal stenosis. The patient is presented after a new coronavirus infection COVID-19 from 2020, prolonged mechanical ventilation through a tracheostomy tube (74 days), the development of medium thoracic cicatricial tracheal stenosis of grade 3 (the lumen of the narrowest part of the trachea is 4 mm) after decannulation and the development of relaxation of the right dome of the diaphragm (according to CT data, the dome is located at the level of the IV intercostal space). The frst stage under conditions of combined general anesthesia and high-frequency ventilation of the lungs was performed to restore the lumen of the trachea by bougienage of the stenosis area with tubes of a rigid endoscope under the control of a fberoptic bronchoscope with further nasotracheal intubation with a thermoplastic single-lumen endotracheal tube with a diameter of 8.0 with a cuff. At the second stage, during thoracoscopic plastic of the right dome of the diaphragm, to provide artifcial one-lung ventilation, a bronchial blocker was used, introduced through the same endotracheal tube into the right main bronchus under the control of a fberoptic bronchoscope.
