One of the problems we had over the last 24 hours was that he is difficult to canulate and it took about 4 or 5 doctors before it was achieved and so fluids did not go up until today.
It is not potassium but sodium and it is very low but they are working on levels at 5.30 which would have been with only the first litre of fluid so hopefully tomorrow morning's blood tests will show better.
They then need to find out why it was low in the first place. Apparently sodium can be a problem for those with stoma's and I do remember the Stoma nurse telling me that food needed to be sprinkled with salt to get used to adding salt again if we a family who omitted it and we are. So I must remember to keep adding it to the food.
