Summary

A 7-year-old male is scheduled for a herniorrhaphy. The child has no prior medical history. Per his parents, he had a previous tonsillectomy with no complications at age 2. He is adopted, so no family history is available. He has a mask induction with sevoflurane. After induction, an intravenous (IV) line is placed. Twenty minutes into the case the resident notes some mild tachycardia and a slowly increasing end-tidal CO2 (ETCO2). What are you concerned about? What tests would you order? Assuming this is malignant hyperthermia (MH), how would you treat it?
