Transforming Crisis Airway Management: Clinical Applications of a Distal Pharyngeal Airway Innovation in Two Cases.

Airway management failure remains one of the most consequential adverse events in clinical practice, with the potential for severe hypoxemia, cardiac arrest, and death. While traditional airway adjuncts, such as oropharyngeal airways (OPAs) and nasopharyngeal airways (NPAs), serve as foundational rescue tools, their limitations, including the inability to access distal pharyngeal obstructions, risk of laryngospasm, and incompatibility with positive pressure ventilation, underscore the need for innovative solutions. The distal pharyngeal airway (DPA) is a relatively novel device designed to extend beyond the tongue base to the level of the epiglottis, addressing the most common anatomic site of upper airway obstruction. We present two cases that demonstrate the lifesaving utility of the DPA in high-acuity airway emergencies. The first case describes a 47-year-old male with a BMI of 46, a history of obstructive sleep apnea and multiple comorbidities, who experienced rapid oxygen desaturation to 60% during procedural sedation for esophagogastroduodenoscopy (EGD). The jaw thrust maneuver proved ineffective; insertion of the DPA device through the endoscopic bite block aperture with bag-valve-mask ventilation restored oxygen saturation within 30 seconds, and the procedure was completed successfully. The second case involves a 69-year-old female who presented in acute respiratory distress following thyroid lobectomy, with a postoperative hematoma causing tracheal displacement and complete obliteration of anterior neck landmarks. Sequential failed attempts with two video laryngoscopes and a supraglottic airway resulted in oxygen saturation declining to 60%. DPA placement with two-person assisted mask ventilation successfully restored ventilation and oxygenation, bridging the patient to definitive airway management and subsequent video laryngoscopy-assisted intubation with a bougie. These cases highlight the DPA as an effective rescue device in both procedural and emergency airway settings, particularly when conventional adjuncts fail. Early recognition of high-risk scenarios, systematic decision-making, team coordination, and access to innovative devices such as the DPA are essential to optimizing patient safety and outcomes across diverse clinical environments.
