I just attended a Train the Trainer session for the Bone injection gun by Waismed. I'm more familiar with EZ-IO and the FAST ONE. The B.I.G. doesn't seem to me that it's all that adjustable. Essentially, it's spring loaded and just pounds through the bone into the marrow, yet there is no way to continue pushing the needle through if the spring doesn't get it all the way to the marrow.

Threw the BIG out a few years ago here now and introduced the EZ IO

It was removed because it is not adjustable and is reasonably traumatic to insert

Used it back in 2006-2007 and anecdotally, we had many issues with it. Currently use the EZ-IO and the old school Jamshidi derivatives.

Yes, a very high failure rate was another reason it was withdrawn here

Anecdotally only - We use BIG at a service I work casual for, It has been attempted many times with about a 60% success rate.

Thanks guys, all good information to know. At a cost of something like 70 bucks a pop, (pun intended) I'm rather disappointed that we're wasting money on them now.

I have also heard, but nothing to back it up other than verbal discussions that increased bone fractures with the big, especially with smaller boned patients. Anyone else get that experience?

I have not heard anything personally but it is certainly plausible given the high amount of force exerted from the BIG

Use it on an alert patient and they will come off the cot. Really only useful for an unconscious patient. Prefer the ez, alert patients seem to move less with it than an IV.

The BIG is old news here also. We tried them and had poor success with getting them to flow as the injection seemed to plug the opening with fragments that had to be forcibly flushed out to flow fluids . EZ-IO works much easier and definitely more gentle on the PT. Now that they have the longer needle it has a high success rate.

Fast 1 worked great, but had a bystander pass out while watching it inserted, pretty gruesome looking tool, took some fore to imbed it.
