Dilys,
I am going through something very similar with my husband, except we were pushed out of hospital at 9 days post op and unfortunately nothing improved when we came home. It has now been 5 weeks since surgery and I am losing my mind. He doesn’t seem like he is sleeping at all, which seems like it could be a big part of the problem. Did your partner struggle with sleep post operation and during the delirium? Thanks for any thoughts.
