Stop fretting, this is quite normal, especially when some one is on morphine.
When my husband had his triple bypass, everything I did was wrong, i decided I was not getting involved with a stroppy drugged up idiot. (the nurses get paid we don't) Oh and when he is better he will not remember a thing.
If I sound hard I'm not, my husband is blind and I stayed at the hospital for five days and nights, got good at picking my moment to go off for a coffee.
So stop worrying, the nurses will have him changed in the morning when he gets his wash.
Try and get a good nights sleep, it will all look better in the morning.
Sunshine.. love and hugs
