Wilderness Medicine Updates Ep. 20 - Out of Hospital Airway Adjuncts: King Tube vs LMA
King Tube vs IGEL for Airway Management
In this episode of Wilderness Medicine Updates, Dr. Patrick Fink addresses a listener's question on whether to use a King Tube or an IGEL as an out-of-hospital airway adjunct. The episode begins with an overview of airway management techniques from mouth-to-mouth resuscitation to supraglottic airway devices. Dr. Fink explains the benefits and drawbacks of various airway adjuncts, including oral and nasal pharyngeal airways. The discussion then shifts to a detailed comparative analysis of King Tubes and IGELs based on retrospective and prospective studies. Dr. Fink evaluates the evidence indicating that IGEL may be more effective and easier to use than King Tubes, particularly in pre-hospital cardiac arrest situations. The episode concludes with recommendations for pre-hospital providers and an encouragement for listeners to share their questions and feedback.
