We’ve all used Epinephrine in varying concentrations either IM, SQ, IV, or IO for cardiac arrest calls, anaphylaxis calls, and some respiratory calls because it also affects beta 2 receptors for smooth muscle relaxation in the respiratory tract, and nebulized in pediatrics for croup.

Why would we use an epinephrine drip? These are useful...

One of the most invasive airway procedures that can be performed by a paramedic is a surgical cricothyrotomy.
