as Dr.Amoushahi said it may be due to allergic reaction to PVC.
also you can use silicon tracheal tubes that has no obvious reaction.
Don't worry it is safe.

Dear Donna and Other anesthetists friends,
The rarely possibility of airways reaction is the reaction to the tracheal tube during general anesthesia.
The tubes are produced with the PVC. An allergic patient may be sensitive to the PVC and his or her asthma exacerbated by it. But it's symptoms and signs appear during anesthesia and disappear after removing of tube. Regional or local anesthesia is choice for allergic patient. For example local anesthesia for tooth removing is very good.

Sincerely Yours

-Hi Donna,
Asthma is a hypersensitivity illness with a wide spectrum, it is true that maybe you have outgrown its pulmonary stages which manifested in your chilhood? But the fact that you have penicillin allergy and chronic sinusitis does not preclude the possibility of having its symptoms again. General anesthesia, as far as i know, is never been implicated as a trigger for asthma reactivation, in fact some anesthetic agents may help relieve airway narrowing though there are other agents which can trigger a reactive airway if introduced inappropriately. Try searching for other triggers which you may consider to avoid and ask your physician/anesthesi ologist for more clarification.
