I-gel 후두마스크 사용 후 발생한 혀의 청색증

The i-gel was designed to avoid compression or displacement trauma from the inflatable laryngeal mask airway (LMA) cuff. We present a case of transient cyanosis on both lateral sides of the tongue observed after use of the i-gel which is believed to have been caused by transient obstruction of the lingual artery due to compression of the tongue. Careful attention is required to reduce injuries associated with direct compression when using LMA including i-gel.
