Submental Intubation with Reinforced Tube for Intubating Laryngeal Mask Airway

Abstract

Submental endotracheal intubation is a simple and secure alternative to either nasoendotracheal intubation or a tracheostomy in the airway management of maxillofacial trauma. However, a submental endotracheal intubation is quite difficult to manage if adverse events such as a tube obstruction, accidental extubation, or a leaking cuff with the endotracheal tube in the submental route occur, which could endanger the patient. This paper describes the use of a LMA-Fastrach™ETT in the submental endotracheal intubation of patients suffering from maxillofacial trauma. One of the patients was a 16-year-old male, and the other was a 19-year-old male. They were scheduled for an open reduction and internal fixation of the maxillofacial fracture including naso-orbital-ethmoidal (NOE) complex, and a zygomaticomaxillary complex fracture. A submental intubation with a LMA-Fastrach™ETT was performed in both cases, and the operation proceeded without any difficulties. These cases show that the use of the LMA-Fastrach™ETT can improve the safety and efficacy of submental endotracheal intubation. This is because the LMA-Fastrach™ETT has a freely detachable connector, and is flexible enough to keep the patency despite the acute angle of airway.
