Tracheal intubation using the Airtraq®: A comparison with the lightwand

Abstract

The Airtraq® laryngoscope is a new tracheal intubation device that has been developed for the management of normal and difficult airways. As with the lightwand, the Airtraq can be used without placing the patient in the 'sniffing position' for direct laryngoscopy. The purpose of this study was to compare the efficacy and usability of the Airtraq with that of the lightwand during routine airway management. One hundred ASA 1-2 patients scheduled for elective surgery under general anaesthesia were randomly assigned to either the Airtraq (n = 50) or lightwand (n = 50). Intubation was performed by one of two anaesthetists experienced in the use of both devices. There was no difference in success rate, intubation time, and haemodynamic response between the two groups. In conclusion, the Airtraq® and lightwand have similar efficacy in patients without risk factors for difficult intubation. © 2010 The Association of Anaesthetists of Great Britain and Ireland.
