Stephanie I know it is easy to say try not to worry too much, I do understand exactly how you feel. My son has had many anaesthetics, over 11! As long as the anaesthetists know about your son's CAH - I am sure he will be fine and because he has CAH they will keep an extra special eye on him. My sons Endo worked out a drug regime for him. Speak to both doctors, it will make you feel easier! I always think of the surgery that the girls with CAH have had and my hearts go out to their mums as well as them. No matter what type of surgery your child is having, it is natural to worry. I hope this helps - and I wish you and your son all the very best! Will be thinking of you. Concerned mum
