Clinical Trial Testing Buzzy Bee vs Vapocoolant During IV Placement

The Buzzy is a vibrating palm-sized device with removable ice wings developed by MMJ Labs Atlanta, GA. It uses Melzack and Wall's Gait Control theorywhich asserts that activation of non-nociceptive fibers can interfere with signals from pain fibers thereby inhibiting pain.

Vapocoolent is a volatile refrigerated liquid, ie ethyl chloride, which is supposed to feel like the skin is numb before insertion of the IV.

A band will be placed on the arm before IV insertion for placebo effect.
