Clinical study was carried out during 116 total anesthesias for endoscopic operations on the larynx, trachea, and bronchi. Multicomponent total anesthesia was based on fentanyl, calypsol, diprivane, and dormicum microdoses in combination with local lidocaine anesthesia of the airways and premedication with nonsteroid antiinflammatory drugs. Interventions on the larynx and proximal part of the trachea were carried out with the patients' spontaneous respiration retained; during interventions on the middle part of the trachea, forced ventilation of the lungs (FVL) was carried out through an intubation bronchoscope; and during total anesthesia for operations on the tracheal bifurcation, high-frequency FVL of the intact lung was carried out. Stable hemodynamics and gas exchange, hypercapnia, and moderate respiratory acidosis were observed in patients operated on under both types of FVL. No serious complications during and immediately after surgery and anesthesia were observed. Hence, the choice of the method of total anesthesia and ventilation of the lungs in endoscopic interventions on the airways depends on the level of lesions and degree of airway obstruction. |
