In 85 patients (mean age 4.6 +/- 3.1 years, range 0-10 years), a prototype
of a new videolaryngoscope was used to provide a display of the intubation
procedure in a paediatric anaesthesia teaching unit. The device provided im
portant information to the teacher about the trainee's problems related to
direct laryngoscopy, difficulties with tube insertion into the larynx as we
ll as the need and extent for anterior laryngeal pressure. Because the vide
olaryngoscope did not impair the normal intubation procedure, it seems to b
e a safe and a benefical tool for teaching and supervising tracheal intubat
ion in children. In addition, it provides a potentially useful aid during d
ifficult laryngoscopy, since the monitor view of the vocal cords was signif
icantly better compared with a direct laryngoscopic view (P < 0.001).
