The Airtraq laryngoscope is a single-use laryngoscope designed to facilitate tracheal intubation in patients with either normal or difficult airways. The aim of this systematic review and meta-analysis was to compare the Airtraq with the conventional Macintosh laryngoscope. Data were retrieved from Medline, Embase, the Cochrane register of controlled trials, and by a manual search of bibliographies. Twelve randomised controlled trials (published between 2006 and 2011) including 1061 patients met the inclusion criteria. The Airtraq reduced intubation time significantly (mean difference -15 s; 95% CI -25 to -4 s, p < 0.00001) used by both experienced anaesthetists and novices, and it increased the first attempt success rate only in novices (relative risk 1.25; 95% CI 1.05-1.49, p = 0.07). The incidence of oesophageal intubation (relative risk 0.12; 95% CI 0.03-0.48, p < 0.05) was significantly reduced by the Airtraq. We conclude that the Airtraq laryngoscope facilitates a more rapid and accurate intubation, especially when used by novices.
