[Hyperbaric oxygenation in the postoperative treatment of children with cicatricial laryngostenosis].

Hyperbaric oxygenation (HBO) was used in the combined treatment of 20 children, aged 2 to 14 years, after reconstructive surgery of the larynx. All the patients had been exposed to tracheostomy. As a result, optimal regimens of compression and decompression of operated children were developed which were 0.025 ata/min and 0.04 ata/min, respectively. HBO was most effective when whole-body and regional hypoxia was applied simultaneously. The optimal pressure in an altitude chamber was 0.9 to 1.0 ata for as long as 40 to 50 min. HBO made it possible to shorten the degenerative-inflammatory process. Positive changes in pH of the wound were regarded as an indication of reductive aerobic metabolism there.
