The continence nurse called yesterday to see how it is going. I told her that I seemed to be able to do it OK and OH is compliant, but I was concerned about my back and what would happen if I was unable to do the catheterisation. She gave me an emergency phone number to call if I was unable to do it and she said she would ask her colleges about my back problem. She phoned me back again later to suggest a gardening stool that could be turned up-side down so that it was a kneeler with arm rests - one like this https://www.nrshealthcare.co.uk/household-aids/gardening-tools/garden-kneeler I think it will do the job and Ive ordered one (if it doesnt work I can always us it in the garden!) Today, though was my worst nightmare. OH had a seizure while I was doing the catheterisation . Fortunately Im well used to his seizures and know how to deal with them, so I just paused and carried on when I could, then put him to bed. I dare say that it would have hurt him while he was fitting, but he would not have been aware of it and having drained his bladder it meant that he could sleep peacefully. He has had a couple of more seizures today, so Ive been a bit on edge listening out for problems. So, Ive got through the worst case scenario and it was OK. Not good, but OK. I think that for now this is working. If something changes, like continued problems with my back, or OH no longer accepting me doing it then I will have to think again, but that is the way of dementia. If it works for now then that is the best we can hope for.
