I avoided this surgury from the time he was 2, he is almost 7. I wish I hadn't now.
The recovery was hell, but it was worth it, no more snoring, no more infections,no more strep, its decreased his apnea, its decreased his asthma, and its increased his focus (strange side effect in boys, it increases focus in a good number of the cases) We spend an ungodly amount of time at NAtional Jewish for the allergies & asthma, they would recomend us to only 1 doc....Dr Werle at Psybeterian. He specializes in children, When we got to the hospital & he was in recovery, the nurse was like "oh you are Werles paitient, your son won't have any complications, Werle does the cleanest job" etc etc etc. His adnoids were larger then an adult males, his tonsils inflamed too. Its worth it, but have both taken at once. My son sleeps like the dead now, no snoring, no thrashing, I can't even hear him. We haven't had an asthma attack & he can breath well through his nose.
ITS TOTALLY WORTH IT!
(But recovery is HELL for you, take the full 10-12 days off, don't think he will recover faster, pay the extra for the med that lasts longer then the codine, and set your alarm so you never get behind the pain.
Still its worth it.
My son does remember the mask, go into the anesthesia room with your child, they let him take his favorite stuffie too... & hold them till they are asleep (they will let you do this), also tell him before how it will be, no lies, tell him why & let him vent afterwords. They will tell you they remember going to sleep and didn't like the smell, but if its ok to tell you then its ok.
The codine can also cause nightmares, so the first couple days while you are using it if you don't get the other med, realize the nightmares are a side effect of the narcotic, not the surgury. Another reason I recomend the other med whose name I can't remember.
