BD instye autoguard angiocaths- difficulty

Hi all,
I am wondering if any of you out there use the BD Insyte Autoguard angiocaths at your facility. If so, does anyone else experience any difficulty with them? I have been starting IV's for over 14 yrs and have always been one of the folks that people come to for difficult sticks. However, with these angiocaths I still get it in the vein, but find it is nearly impossible to thread the catheter up the vein. Other nurses in my dept have adopted the technique of threading the entire needle and catheter up the vein because of this. I hate to do that, it is so traumatic to the vein esp. if using irritating meds. I learned the "textbook" technique of threading catheter only once you've acheived flash and advance a bit further. (hard to change!) Any tips or tricks would be helpful! Thanks, SG

Funny you mention that, I went on their product website and they instruct the user to do just that- rotate barrel 360º. What does that do? No one at my facility does that. Could that be the reason we can't push the catheter off the needle very far to thread? Thanks, SG
