IT Pump nurses?

Hi!  Just wondering if there's any other nurses out there who fill intrathecal pain pumps.  I feel like there's not many of us out there.  Would just like to hear how your experiences are with this?  I do not particularly enjoy it at all, it's very nerve wracking for me, but it's a role I have to do at my job in order to keep working there.  I've had a few scary things happen, which is why they make me so nervous.  Would love to hear your tips and advice!
