[Provision of artificial ventilation of the lungs during endolaryngeal surgical interventions using a high-energy...

To ensure controlled lung ventilation in endolaryngeal surgical interventions, using a high-energy laser, use was made of normal frequency jet ventilation (NFJV) and high frequency jet ventilation (HFJV) through a non-inflammable fluoroplast catheter supplied at a distal end with a device fixing it in a central position. HFJV seems preferable, as endolaryngeal manipulations become more convenient. The study was performed in 118 patients. Venturi effect was observed only during ventilation through a tracheostomic canule. It has been established that, unlike NFJV, in HFJV gas exchange parameters are much better, though oxygenation in NFJV is satisfactory in all the patients.
