This is the second time it has happened. Today, and exactly two weeks ago. We have got up in the morning to find that the Sil 13mm canula just hanging out of his site. We are putting the set through the Tagaderm (as per our rep due to other issues), and on his hip/butt (again, our only real viable space). Rep watched our technique, so that isn't an issue. You can't even see any visible sign of the canula when it is inserted, so it is all the way in to begin with. My only thought is that his rolling around at night, possible rubbing at the site, is somehow lifting a little part of it out, and then it gets caught on something and pulled out. Anyone else had this happen, and on a continual basis?
