The Universal Adapter for Smartphones^® c an record s till images and movies during intubation using the monitor display and recording functions of a smartphone. Here, we describe the successful use of the Airtraq Double Lumen^® with the Universal Adapter for Smartphones^® for airway management during anesthesia in a patient with intubation difficulty.

A 78-year-old man required thoracoscopic upper lobectomy for a pulmonary tumor. Preoperative examination revealed micrognathia, mouth opening equivalent to a three-finger width, Mallampati Class II, mentum-hyoid bone distance equal to a 2.5-finger width, hyoid bone-thyroid cartilage distance equal to a two-finger width, and Class I findings in the Upper Lip Bite Test. After inducing anesthesia and confirming the feasibility of mask ventilation, we administered 70 mg of rocuronium and inserted the Airtraq Double Lumen^®. The Universal Adapter for Smartphones^® connected to a 4-inch iPod Touch^® was attached to its eye cup, through which the iPod Touch displayed images for easy visualization of the glottal area.

Prompt and smooth intubation with a 35-Fr double-lumen tube (DLT) was achieved. There were no adverse events associated with intubation.

Combination of the Universal Adapter for Smartphones^® and the Airtraq Double Lumen^® can facilitate smooth tracheal intubation with a DLT in cases of difficult intubation.
