AB  - OBJECTIVE: This study evaluated the visibility of echogenic needles with older 
      ultrasound devices in an in vitro phantom study. METHODS: We compared three 
      echogenic needles from B. Braun (BB), Unisis (UN), and Hakko (HK) with a 
      nonechogenic needle. Each needle was inserted into an ultrasound phantom 10 times 
      at 30 degrees  and 45 degrees  with the bevels up. The captured images of the needle and 
      background contrast were digitally analyzed, and the median of 10 insertions for 
      each angle was calculated to determine objective needle visibility. Needle images 
      were also shown to 12 anesthesiologists to evaluate subjective visibility on a 
      five-point Likert scale. RESULTS: The shafts of all the echogenic needles were 
      significantly more objectively visible than the nonechogenic needles. Subjective 
      visibilities of the BB and UN needles were significantly higher than that of the 
      nonechogenic needle. Therefore, the BB and UN needles were judged to have more 
      than fair subjective visibility. However, subjective visibility of the HK needle 
      was consistently and significantly lower than that of the BB and UN echogenic 
      needles. At 45 degrees , the HK needle had nearly the same poor visibility as the 
      nonechogenic needle. CONCLUSION: The results of our study indicate that the BB 
      and UN needles are more visible than nonechogenic needles in an ultrasound 
      phantom, even on older devices.
