BackgroundThe study was designed to investigate the success rate and time of insertion intraosseous access during simulated resuscitation.Material And MethodsThis was a randomized crossover study involving 107 paramedics. They were timed from start of insertion attempt to successful insertion and asked to score perceived difficulty of intraosseus access devices. Bone injection gun (BIG) (WaisMed Company, Houston, TX), EZ-IO (Vidacare, Shavano Park, TX) and Jamshidi (Carefusion, San Diego, CA) were used in this study.ResultsSuccess rates for first intraosseus iniecition attempt were higher for the BIG (91.59%) than EX-IO (82.66%) or Jamshidi (47.66%). Mean procedure time was 2.0±0.7 vs 3.1±0.9 minutes for EZ-IO vs 4.2±1.0 minutes for Jamshidi.ConclusionsThe use of BIG is associated with excellent success rates for insertion and appears easier to use than EZ-IO or Jamshidi Intraosseus Needle. Further work to evaluate the use of the intraosseus access device in the emergency medical services is required.Copyright © 2014 Elsevier Inc. All rights reserved.
