Will hospital records show the names of all the doctors and nurses who worked with a patient during an inpatient stay two years ago?

I had a near death experience in a hospital two years ago, and I don’t even know the names of the people who saved my life.

When it happened, I was very naive and completely did not understand the severity of the situation. I complained a lot and did not show them the appreciation they deserved. I’d really like to send them cards thanking them. Can you assist me on how I might go about getting all the necessary information and carrying this out?
