Technical description of a modified jet ventilation injector for airway laser surgery in neonates and infants: retrospective analysis of 20 cases.
BACKGROUND
The authors modified an adult jet ventilation injector (Hunsaker Mon-Jet Ventilation Tube(®)) to be able to provide transglottal high-frequency jet ventilation (HFJV) in small children undergoing laryngeal procedures with CO2 laser.


METHODS
Retrospective review of the anesthetic records of all children younger than 2years undergoing transglottal HFJV for CO2 laser laryngeal procedures using this modified adult injector between 2006 and 2013.


RESULTS
Nine children (5 boys, 4 girls) were identified who underwent a total of 20 procedures. Mean age was 7.4 ± 6.9months, and mean weight was 6 ± 2.8 kg. No complications were observed with the use of HFJV or this modified injector.


CONCLUSIONS
In experienced hands, this modified injector ensures excellent visibility and field access to the surgeon as well as adequate ventilation during laryngeal laser surgery in infants.
