Background/need. Office-based sedation has become increasingly commonplace in dental offices in recent years, allowing for practitioners to provide broader scope of care for their patients. Maintaining high standards of safety is of utmost importance when sedation is utilized in the office-based setting, especially for patients deemed at a higher-risk for intraoperative airway obstruction. This demographic includes but is not limited to individuals with a medical history significant for obstructive sleep apnea, chronic obstructive pulmonary disease, and morbid obesity. Presently, a wide variety of airway devices exist for use in the event of airway obstruction. However, in the context of oral and maxillofacial surgery, placement of these devices can encroach upon the surgical field, extending the perioperative period and putting the patient at greater long-term risk for maintaining adequate oxygenation. Methodology. The authors describe a preliminary technique trialed in our offices which utilizes a size 5.0 endotracheal tube (5OET) as an adjunct supraglottic airway to help mitigate the issue of oxygen saturation maintenance, as well as unimpeded access to the oral cavity. Implementation of the device requires identifying appropriate candidates during preoperative screening and placing the device through the nare and securing it above the glottis. Device Description. The ‘tube kit’ is comprised of a standard size straight 5.0 cuffed oral ETT, a 5-mL syringe for inflation of the cuff post insertion, lubricant, flex extension tubing, end tidal sampling line for capnography, tape for securement of the 5OET, and an anesthesia breathing circuit. Optional equipment pieces include an elbow connecter and a foam piece for comfort. Results/Current Status. Preliminary results have demonstrated oxygen saturations maintained above 98% when the 5OET is placed preoperatively. Continued use of the trial device will inform the development of a tube by our clinicians, and its efficacy will be studied in our offices. The next steps will be to start developing a pilot cuff that will be submitted for patent approval after its use in IRB-approved clinical studies.
