The High-Risk Airway.

The high-risk airway is a common presentation and a frequent cause of anxiety for emergency physicians. Preparation and planning are essential to ensure that these challenging situations are managed successfully. Difficult airways typically present as either physiologic or anatomic, each type requiring a specialized approach. Primary physiologic considerations are oxygenation, hemodynamics, and acid-base, whereas anatomic difficulty is overcome using proper positioning and skilled laryngoscopy to ensure success. It is essential to be comfortable performing alternative techniques to address varying presentations. Ultimately, competence in airway management hinges on consistent training, deliberate practice, and a dedication to excellence.

The Case for Bougie Use on Every Intubation.

Despite its value in emergency airway management, the endotracheal tube introducer, commonly known as the bougie, has traditionally been a point of disagreement between providers. It is typically viewed as a "rescue" device and not a primary airway tool. However, its value as a primary device during plan A has recently been recognized. Two studies have shown increased first-pass success using a bougie on the initial attempt. Additionally, bougie use on every intubation increases provider comfort with the device so that, on a truly difficult intubation, the skills and mechanics are instilled. In the out-of-hospital and critical care transport settings, intubation is often inherently more difficult because of varying environments. For these reasons, the bougie should be integrated into the first intubation attempt in emergent intubation.

Alternatives to Rapid Sequence Intubation: Contemporary Airway Management with Ketamine.

Endotracheal intubation (ETI) is a high-risk procedure commonly performed in emergency medicine, critical care, and the prehospital setting. Traditional rapid sequence intubation (RSI), the simultaneous administration of an induction agent and muscle relaxant, is more likely to harm patients who do not allow appropriate preparation and preoxygenation, have concerning airway anatomy, or severe hypoxia, acidemia, or hypotension. Ketamine, a dissociative anesthetic, can be used to facilitate two alternatives to RSI to augment airway safety in these scenarios: delayed sequence intubation - the use of ketamine to allow airway preparation and preoxygenation in the agitated patient; and ketamine-only breathing intubation, in which ketamine is used without a paralytic to facilitate ETI as the patient continues to breathe spontaneously. Ketamine may also provide hemodynamic benefits during standard RSI and is a valuable agent for post-intubation analgesia and sedation. When RSI is not an optimal airway management strategy, ketamine's unique pharmacology can be harnessed to facilitate alternative approaches that may increase patient safety.
