Use of a battery-operated needle driver for intraosseous access by novice users: skill acquisition with cadavers.

Study Objectives: We determine skill acquisition and performance by using a battery-operated, intraosseous needle driver in cadavers.

Methods: This was a prospective study of the EZ-IO, a battery-operated intraosseous needle driver (Vidacare Corp). Operators received a 5-minute presentation (with 1 insertion demonstration) and then performed 3 tibial insertions on a cadaver.
