48 yo male with questionable hx of a nephew who had a MH reaction and died at age 3. The current pt has had a general anesthetic for lap chole about 10 years ago with sux and isoflurane. I've done other relatives (parents and siblings of the child who died) in the past with a non-triggering anesthetic. Would you do the current pt (uncle) with a non-triggering anesthetic or not?
