Hi @therese0327, good to have you here on Mayo Clinic Connect.
I'm sorry your husband had to go through an open heart surgery under extreme circumstances.
That must have been very scary for you both!
I'm glad he's extubated (the "thing" in his throat for breathing)...I bet they get him up and out of bed pretty quick too.
So, I had open heart surgery too...but it was not a bypass. It sounds like you are referring the the saphenous veins they harvest for the bypass?

Here's my advice: ASK! Ask the care team before you try any creams or lotions or potions on it. For my chest wound I was told to let it air dry, wash with liquid soap, and not put any lotions on it until it was completely healed.

I know this is not the same place as his leg wounds, but just to be sure, ask the doctor or nurses. They deal with these everyday.
He's blessed to have you by his side as he goes through the recovery.

It takes time to heal the chest wound and he's probably going to be pretty sore for several weeks/months.
Tell him it gets better, I promise!! It might be some time before he can swing a golf club though...but he can use it as an excuse for his golf handicap!
How are you doing? Are you able to talk to anyone about this scary new situation?
