BackgroundThe intubating laryngeal mask airway (ILMA) allows providers to blindly intubate through the device. We report a case of foreign material obstructing passage of an endotracheal tube (ET) through an ILMA.Case ReportA 45-year-old man with unknown past medical history was found obtunded with an apparent intentional drug and alcohol overdose, and required tracheal intubation. We opted to use an ILMA to optimize preoxygenation prior to intubation. His upper dentures were removed and an ILMA was inserted without complication; ventilation was easily performed. Blind tracheal intubation was attempted; the ET was inserted through the ILMA and was unable to be advanced past 15 cm despite multiple attempts, including repositioning the ILMA and rotating the ET. The ILMA was removed to prepare for video laryngoscopy. He was subsequently successfully intubated using a standard geometry video laryngoscope, which showed no anatomical abnormalities. After the case, the ILMA was inspected and the bowl of the ILMA was found to be occluded with denture adhesive. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report demonstrates that it is possible that foreign material within the ILMA can make successful intubation impossible, despite successful placement and ventilation through the device. Maneuvers may be performed to attempt successful ET intubation, but when unsuccessful, removal of the ILMA and alternate airway management must be performed.Copyright © 2019 Elsevier Inc.
