As terrifying as it is, I wonder if a large part of it was because anesthesia on infants is a lot more dangerous because of the low body weight and unknown metabolism. That could lead to a lot of complications, so if there was reason to believe that it wouldn't otherwise impact the infant (no long term memory) it could be more ethical and safer to not do so. That said I'd assume they've solved those problems now if they're using it.
