Interesting problem. I frequently have the same dilemma - whether to tube a patient in the pre-hospital arena, or run to the hospital and let them do it there. I am about finished writing a blog about just one scenario. The bottom line is, every time I have thought to myself, "I'll wait until we get to the hospital<" I have regretted it. There is this misplaced thought that, once the patient has been delivered to the safety on the resus room, everything will go smoothly. This is often not the case, and the fact that there are so many people, with no team leader, is usually the cause. Of course you did the right thing. You have little experience in IO insertion, and your colleague has less. For you to have tried to get an IO in, and possibly failed, would have taken far too long, and 6 minutes is not a long time. However, given the alternative scenario, of having the experience and confidence to get a line in a child, the answer has to be "don't delay the line." Great blog, great inspiration to the rest of us.
