Tag: Intraosseous

Originating in the 1800s and commonly performed through the 1960s, an intracardiac injection was once viewed as the most direct method for delivering medication, such as epinephrine, to the heart during cardiac arrest. Today, however, this invasive procedure is largely considered obsolete in emergency medicine due to significant risks and the development of far safer and more effective alternatives.

While millions of injections are administered daily, patient perception of pain can vary drastically depending on the method. The question of what is the most painful injection method depends on several pharmacological and physiological factors, but emergency procedures like intraosseous access are widely cited for causing extreme pain.
