A patient exhibits supraglottic swelling. What intervention should the therapist recommend?

In cases of supraglottic swelling, the most appropriate intervention is the use of racemic epinephrine. Supraglottic swelling can be indicative of upper airway obstruction due to conditions such as croup or anaphylaxis. Racemic epinephrine is a medication that acts as a vasoconstrictor, leading to reduced swelling and improved airflow in the upper airway by constricting blood vessels and decreasing edema.

This action is particularly essential in managing acute airway emergencies, as rapid intervention is necessary to prevent respiratory distress or failure. The delivery method, typically through nebulization, allows for targeted relief in the upper airway, offering immediate benefits.

Other treatments, while they serve important roles in airway management, do not provide the same immediate effect. For instance, inhaled corticosteroids, while useful in the long-term management of inflammatory airway diseases, do not act quickly enough in an acute situation like supraglottic swelling. Oxygen therapy is crucial for addressing hypoxemia but does not directly alleviate the swelling itself. Antihistamines can help in allergic reactions but are not effective for severe swelling that requires urgent intervention. Thus, racemic epinephrine is the best option for addressing acute supraglottic swelling.
