Hi there,
Sorry you and your wife are having such a touch time. I didn’t have the delusional symptoms when I had my autoSCT but it very much reminds me of when my Mum was in hospital having a hip replacement. She caught a simple urine infection and it caused her to be totally delusion, refusing medication not reckoning people. It was very scary at the time, and I had hard time believing nurses when the said “don’t worry, it’s the infection and antibiotics will fix it”. Sure enough it took a couple of weeks but antibiotics did work. Your wife’s Hickman line infection maybe causing her confusion very possibly?
The sore mouth is very common with the melphalan chemo for transplant. I had it quite bad for 4 or 5 days, the nurses gave me co-codamol and oral morphine which helped. It goes away quite quickly once white blood counts starts to come back up.
Best wishes, hope things improve soon for you
Laura
