General pediatric anesthesia for tonsillectomy Need to find adverse reactions for Sevoflorzine(spelling ?)?

My son age 8 had a tonsillectomy. Surgery went fine but after transfer from recovery to his dayop room within 15 minutes he developed a severe migraine. He had been given Tylenol with Coedeine Elixir after returning to his room. I don't think the migraine was caused by the elixir as he received it every 4-6 hours as needed without any adverse reactions. His Pediatrician directed me to find out the anesthesia he was given since his migraine was so severe he should not receive that med again. I have the Anesthesia Report but I could not find this med in my Nursing 2006 Drug Handbook and I could not access the PDR website because I live in a rural area of PA without street addresses just Rural Route Delivery. I may have spelt the med incorrectly because I cannot read the handwriting after Sev (could be any of the following: Seveflorzin; Sevoflorzin; Sevaflorzin; or the ending may be zine) I appreciate your answers.

The anesthetic drug is most probably SEVOFLURANE, an inhalational anesthetic agent.

I searched the literature to check whether sevoflurane could cause migranes, but could not find a convincing evidence. All inhalational anesthetic agents cause a degree of dilatation of blood vessels in the brain (which is one of the theories for migraine) but the effect is short lived and reversible once the anesthetic is switched off.

There are reports showing association between sevoflurane anesthesia and convulsions in a small number of pediatric patients.

Sevoflurane is the popular pediatric anesthetic because of its two important properties i) non pungent odour ii) does not irritate the airways.

Check with your doctor, whether to avoid sevoflurane in future.
