Visualization of the Larynx With the Airtraq Laryngoscope and Image Transmission

Detailed Summary

The Airtraq is a battery powered single use optical laryngoscope with a channel to hold and guide the tracheal tube into the trachea. It enables tracheal intubation in patients with normal and difficult airways, by enabling laryngoscopy without neck movement. As a single use device, it is cost effective to have these placed in emergency equipment kits, and for use by emergency and military personnel. However, it does have several limitations. The Airtraq requires the user to place his/her eye to the eyepiece in order to see the advancement of the laryngoscope and the tracheal tube, which may be difficult if the patient is on the ground or in emergency scenarios. Only the user can see through the eyepiece and any assistants are unable to view the larynx, this makes it difficult for assistants to help the operator. Many handphones now incorporate high quality cameras. In this study, we will evaluate the effectiveness of using the iPhone to aid laryngoscopy with the Airtraq optical laryngoscope during laryngoscopy and intubation in 30 patients presenting for elective surgery under general anaesthesia. We have manufactured an attachment that fits over the eyepiece of the Airtraq, to hold an iPhone to the eyepiece. This will enable to operator and assistants to simultaneously view the insertion of the Airtraq, view the larynx and view the passage of the tracheal tube into the trachea.
