Hi I've been reading this forum regularly since hooking up to my pump on the 19th January but this is my first time posting a question. My cannula came out the other night in my sleep. I reckon it had been out a couple of hours or so as I had done a 2am bs and all was fine then. With bleary eyes at 6am I replaced it and although it felt uncomfortable, I thought it would settle down as it usually does within half an hour or so I thought no more about it. By 2pm it was bugging me more so I decided to replace it and start again. I fitted the new one and rather than wait before removing the old one I couldn't wait to pull it out as by then it was very un-comfortable. However, for the first time since starting pumping, blood shot out. I was at work in a back office in my suit. My shirt instantly absorbed the blood and I looked like something out of Texas chain saw massacre! My only option was to return home for a change of clothes. Just wondered if this had happened to anybody else and if so how often? It's kinda put me off replacing a cannula/infusion anywhere else other than home. There was no pain although it has left an almighty bruise. I'm using a Teflon cannula as supplied by Roche for a Accu-Chek Spirit.
