Case Two occurred in the operating room. The patient initially coughed on the endotracheal tube. No generalized rigidity was noted. A tourniquet had been inflated in the leg <20 min when minute ventilation had to be increased to 3 times expected just to keep end-tidal carbon dioxide (ETCO2) at 35 torr. Cardiovascular function was stable. There was no obvious myoglobinuria. But the anesthesia providers suspected MH. The patient was cooled. 2 mg/kg of dantrolene was given. Bicarbonate and fluids were also given. ETCO2 became normal during normal minute ventilation. Post-operative creatine kinase, an enzyme released from injured muscle, was 46,000 IU (normal <200iu). There was respiratory muscle weakness that eventually resolved. The patient made a complete recovery and was referred to MHAUS. Is this classic MH?
