Is there a reason why you are interested in another drug? I'm just trying to figure out why another drug would be something that you WOULDN'T worry about...
Both of my kids have had Versed. Children's doctors calls it "giggle juice". It makes them compliant and relaxed. For my 2 year old who was getting his tonsils removed, they picked him up and walked with him out of the waiting room waving goodbye to me. That was a pretty good trick, too, since I was a nervous wreck and trying my hardest not to cry in front of him. With my older son, the first time he had it, the doc walked in to see how the medicine was taking effect, and my son said to him "You look like you have 2 heads!" The doc chuckled and said "The medicine is certainly working!"
My mother was given Versed before surgery and it affected her memory. She didn't remember going into surgery at all. My mother is elderly, so that might be because of her age.
I would not worry about the Versed. They obviously want her awake, and the Versed probably is their drug of choice for that.
