Hi,
My daughter had a CT scan before adenoid surgery in May. She is 3 and the CT scan was over at Specially for Children. She did have to be sedated because she was just too afraid of the big machine to climb aboard, even after the techs valiantly played with toys, had me demonstrate lying on the table, lifting the table up, going through the "tube" (it's an open machine), etc. I'm sorry that I'm blanking on what particular medication they gave her, but we waited together in a little room, with a bed, toys, etc., as she just became sort of goofy. Then, she very obligingly had the CT scan, which took all of 10-15 minutes. The only really unpleasant thing was that she was even too afraid to drink the meds, so the techs very gently wrapped her in a sheet and administered it. That was tough and, I learned a few days, when she had the surgery, unnecesssary. The nurses in the pre-op (across the hall, as it happened) suggested that we all have a "tea party" when it came time for sedation. They brought three cups - my husband and I got Gatorade - and we all drank up. My daughter did very well then, too. Your daughter is younger, so this all might go smoother, but it's quite manageable, if not the most fun in the world! Wishing you well, J.
