Some good articles to look up are: http://www.healthanswers.com (search "acute adrenal crisis") - that article is excellent regarding symptoms of a crisis that you should watch for. Also: http://www.emedicine.com (click "Search Textbooks") Search "Dehydration" - there is an excellent dehydration article on that site (Dehydration - Pediatrics). I lost a 3 year-old daughter to an adrenal crisis in June 1999 (she leaves her salt-wasting CAH twin). I can honestly say that had I found and read information on this website even two days before that, she would still be alive. There seem to be so many "not good" endocrinologists out there - and I won't comment on this board my thoughts about the endocrinologist we were seeing. When a CAH child is ill with anything, be ready for a hospital trip for an IV to support low blood glucose, low blood pressure, and dehydration (definitely do go immediately if the child is vomiting & can't hold down fluids). Within just a matter of a few hours, you can be in a situation that will result in the child deteriorating to the point of entering into brain damage, seizures, shock and death. Also, my experience is that the emergency room personnel were not familiar enough with the terms "adrenal insufficiency," "adrenal hyperplasia" OR "congenital adrenal hyperplasia" - the matter was told to them in those 3 terms.
