Which method makes emergency shoulder IV placement easiest? study tests 4 techniques.

This study compared four methods for finding the correct spot in the shoulder to place an intraosseous (bone) IV, used in emergencies when regular IV access is not possible. Sixty clinicians with no prior training on this specific site tested one method each. The goal was to see which method was easiest to use, gave the most confidence, and led to the most accurate needle placement.
