Yes, I'm sure that's why. How do you feel about that? Is she really nervous? If not, she would probably be fine with a mild sedative. Actually, I'm surprised that they are doing that at all because several times during the procedure, they will need her to hold her breath while they extract the samples of kidney. The kidneys move when we breathe so in order to get thee sections, the breath has to be held. So, I guess Im not sure what to tell you here. Maybe ask your doctor about that.
