In recent years, various types of indirect laryngoscopes have been developed. Nevertheless, no conclusions have been drawn about which type of indirect laryngoscope is most effective for tracheal intubation. We performed a systematic review and meta-analysis to determine whether the Airtraq® or the GlideScope® is more effective for tracheal intubation. ⋯ In this meta-analysis, use of the Airtraq indirect laryngoscope did not result in improved success rate, glottic visualization, or intubation time in tracheal intubation compared with the GlideScope. Trial sequential analysis suggests that further studies are necessary to confirm these findings.
