I had a relatively short operation under general anaesthetic a few weeks ago. This was done at very short notice so my normal care team were not involved at all. The surgical team were actually delighted that they didn't have to do anything involving my diabetes while "under", as the pump takes care of everything. I did a pre-op test at 5.7, and bizarrely afterwards was at 9.4, that was the only blip in the whole procedure. Not sure what your guys are getting so flustered about?!
