Comparative Study
[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. ⋯ 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.

In 42 children aged 2 months to 16 years who had foreign bodies and blind wounds in the maxillofacial region, the authors examined the causes of damages which had caused penetration of foreign bodies into this anatomical part. Clinical examinations showed that there was a relationship between age, the nature of damage, and the variety of foreign bodies in children in contrast to adults. A working scheme was proposed, which reflects the nature of foreign bodies and blind maxillofacial wounds depending on the physiological periods of childhood.
