Recently my failsafe 6-year-old son went into hospital to have grommets in and his adenoids removed. Right up until he went into the operating theatre he amazed us with his great behaviour and how he dealt with the whole process. The minute he woke up he was so aggressive, rude, would not co-operate and was back to our little monster again.  We couldn't wait to slink out of the hospital with him and get home. The next day he was still agitated and demanding. Do you think the anaesthetic and medication he received for this procedure could cause these sort of reactions?  I know kids do react to going into hospital etc but the change in him from before and after was so dramatic I just have to wonder if it could affect him. – by email, NSW [General anaesthetics are usually OK but medications before and after the procedure can cause bad side effects. You can discuss this with your anaesthetist beforehand, see the free introduction to Friendly Food on www.cs.nsw.gov.au/rpa/Allergy/default]
