I wouldn't have called an ambulance, I would have cooled down and hydrated the child. If I had failed in doing so and for some unknown reason the temperature had carried on rising and the parent had refused to give me permission to use an antipyretic I would have driven the child myself to A+E especially if there was a history of febrile convulsion. Fair enough.. Although it is always different when you actually are in that kind of situation yourself.. you are just 20, abroad, new to a job, new to the family/the child/the country/ the language/EVERYTHING and dealing with kids is never easy with so much at stake, I was just awfully worried and simply helpless - but afterwards and in theorie everything seems to be so easy and so obvious - silly me:-)
