[Transtracheal jet pulmonary ventilation as a measure for preventing hypoxia during reconstructive maxillofacial operations].

Anesthesia including high- or low-frequency transtracheal jet ventilation of the lungs was used in 52 patients with maxillofacial abnormalities subjected to repair surgery. The number of respiratory cycles was 20 per min in 1 group and 120 per min in the other. Intubation of the trachea was started 20 min after ventilation was started. Transtracheal jet ventilation of the lungs prevented hypoxia during intubation of the trachea in such patients. High-frequency jet ventilation of the lungs may be a method of choice in such cases.
