Today we went to see family 2 hours away for some early Christmas fun. Everything was doing good, BG was 131 before lunch (woohoo!), had some homemade pizza, a small muffin, and a couple cookies. Gave the "pretend" bolus and the real stuff to cover carbs. We opened presents then DH took the boys to the park and they played for about an hour. When they got back DH said the pump had been making some alerts so we checked it out and it said that the pump needed to be primed (Why did it do that when we had only set it up 2 days ago and primed it then? And what would cause that?). We are only using saline so I hadn't brought any extra stuff with us for that sort of thing so we decided we'd just fix it once we got home. After that we headed home (BG should have been checked at this point but wasn't ). An hour into the drive we stopped to get some dinner and checked BG, it was 434!!!!! , I am guessing we totaly estimated wrong when we calculated how many carbs he had eaten at lunch. We gave correction and insulin to cover carbs eaten for dinner right away. When we got home we checked BG and it was down to 260 Much better! We did a site change, ( I'm not sure it that was totaly neccessary since the pump only needed to be primed?) Refilled cartridge, inseted new canula, etc and everything was back running smothly. Thoughts, suggestions, what would you have done?
