In which situation would you use adrenaline via intranasal administration?

Using adrenaline via intranasal administration is specifically appropriate when dealing with clinically significant bleeding from the nose. In cases of epistaxis, adrenaline can serve as a vasoconstrictor, helping to reduce blood flow to the area and promote clotting, thereby controlling the bleeding more effectively.

While adrenaline is a critical medication for various emergency situations, such as cardiac arrest or severe allergic reactions, its intranasal route is not typically indicated for these conditions. Cardiac arrest generally requires intravenous access for medication delivery, and severe allergic reactions are more effectively treated with intramuscular administration of adrenaline. Chronic obstructive pulmonary disease (COPD) also does not warrant intranasal adrenaline, as treatment usually focuses on bronchodilators or steroids. The intranasal route is specially used in specific scenarios like significant nosebleeds due to its practical application in controlling localized bleeding.
