Reminder: hospital induced delirium is real

My husband was released from 2.5 days in the hospital. I spent all day Sunday and Monday with him except to run home to feed the dogs and let them out to pee. I left the hospital at 10 both nights to sleep at home. First night he had sun downers, calling me multiple times until 2:20 am. The 2nd night was pure hell. We live in a remote community with a 25 bed hospital. Everyone was wonderful. 2nd night though the phone calls escalated. I had never heard my husband that angry in 35 years. He was threatening to call the police, he was being held hostage and attempted to leave the hospital. At 1am while on the phone with him I offered to come back and nurses felt that was probably the only solution. When I arrived at 1:30am I managed to get him back in bed and calmed down and I stayed the rest of the night lying next to him. I must have looked like the walking dead in the morning because the nurse told me to go home and take a hot shower (I did) and they would make sure he was ok. When I arrived back at the hospital this wonderful nurse talked to me about hospital induced delirium and for them, it wasn’t uncommon. As the morning progressed he was his happy self, not remembering a thing. He fell right back into our normal routine once we were home. The doctor did explain they prefer not to attempt different medications during these episodes if at all possible. Instead they attempt to calm the person by listening to their fears and trying to reassure the person. My husbands fear was I had abandoned him, so I was the solution.
Every person is different, but for some like my husband, the hospital situation makes him spiral into delusions. (He did a similar thing 2.5 years ago in the same hospital). I had never heard of this until I experienced it 2.5 years ago and someone on this site told me about it.
