The Airtraq (TM) optical laryngoscope became available in paediatric sizes in the UK in May 2008. We conducted a randomised, controlled trial comparing the Airtraq with conventional laryngoscopy during routine anaesthesia in children. We hypothesised that the Airtraq laryngoscope would perform as well as conventional laryngoscopy. Sixty patients (20 infants and 40 children) were recruited. The mean (SD) intubation time using the Airtraq was longer than conventional laryngoscopy overall (47.3 (32.6) vs 26.3 (11.5) s; p = 0.002), though the difference was only significant for children (p = 0.003) and not for infants (p = 0.29). The Airtraq provided a better view of the larynx compared with conventional laryngoscopy (in infants (percentage of glottic opening scores 100 (95100 [90100]) vs 77 (5090 [40100]), respectively; p = 0.001; visual analogue scores for field of view 9.2 (9.29.5 [8.210.0]) vs 6.8 (5.18.0 [4.710.0]), respectively; p = 0.001). In children, the Airtraq provided a similar view of the larynx (percentage of glottic opening scores 100 (100100 [40100]) vs 100 (90100 [50100]), respectively; visual analogue scores for field of view 9.2 (8.610.0 [7.010.0]) vs 9.2 (8.610.0 [5.610.0]), respectively; both p > 0.05), compared with conventional laryngoscopy.
