After heart surgery in 1980, does it sound normal to have been made to take extremely hot baths?

I am trying to figure out why I was forced to take extremely hot baths after my corrective heart surgery in 1980? The baths were so hot I could not feel my skin, I turned beet red, and I would have to be held up by the nurse because I would go unconscious. I was 5 and 1/2 years old.

Heart Surgery?

I just found out my dad has to have emergency heart surgery. A few years ago he had a triple or quad by-pass, forgot which. Well, today, found out he is only pumping 50% of the blood he needs through his heart, and that his heart is damaged. I don’t have more details than that…what are his chances to survive the surgery? He is a smoker, works long hours…I’m obviously scared. He is 55 years old.
