Plunger?

I've had syringes not want to get going before, I think it's a suction thing. Not sure this is really what you are talking about, but I think if you push some of the med out the needle tip during your bubble check (just a drop, then flick so no residue is on the outside of the needle) before you dart the patient, you might avoid that little problem.

Did you hit bone? I've seen this happen in that situation before.

I didn't hit bone I know that for sure (I always do the grab technique and make sure I've got the muscle) and I do put out a little drop, but I never thought about flicking it off (usually it falls off anyway), maybe it was that? It was a thick medication too, it never usually gives me problems. Is there anything you've done once you've realized it's not going to move that fixes the problem?

Another question, now I'm doubting myself.. Had I hit bone would I have gotten the bubble from aspiration still?

You will KNOW when you hit bone, it makes me shudder. It could just be as simple as a defective needle..I've had my fair share

I thought we were going to be talking about toilets.

I think that happened to me once years ago, something may have been defective.

If you hit a bone, you would know it.

OP - I hope you saved the syringe & followed your employer's process for reporting defective/malfunctioning equipment. This could be just a fluke, but it could also be the result of a more serious manufacturing problem that needs to be addressed.

I've only hit bone once and I cringed. Luckily I don't think the patient noticed.
