Modified Retrograde Nasal Intubation: A New Airway Technique and Devices.

Abstract

Nasotracheal intubation remains an underused but invaluable technique for securely managing the airway during oral and maxillofacial surgery. In this article, we present a modified clinical technique that allows for the potential introduction into clinical practice of 2 new airway devices: a nasal laryngeal mask airway and an interchangeable oral/nasal endotracheal tube. We hypothesize that with the use of proper techniques, these devices can add new and safer alternatives for securing an airway by the nasal route. The advantage of this novel technique is that the airway is secured by the oral route prior to performing a modified retrograde nasal intubation, eliminating the danger of profuse epistaxis precipitating a "cannot intubate, cannot ventilate" scenario. In addition, the design and materials used in the components of the devices may minimize trauma. The authors aim to inform clinicians about the indications, physical characteristics, and insertion/removal techniques related to these new devices.
