To avoid inhalational anesthetics, total intravenous anesthesia (TIVA) is required in patients with a predisposition to malignant hyperthermia (MH). However, propofol, which is frequently used, may be avoided in patients with egg allergies because of the contraindications in the drug information. Furthermore, some patients may not consent to the use of propofol. We report a case of TIVA using midazolam and dexmedetomidine as substitutes for propofol in a pediatric patient with egg allergy and a predisposition to MH. A 10-year-old boy was scheduled to undergo perforated drainage of an epidural abscess. He had egg allergy, and his uncle had been diagnosed with MH. He also developed a generalized drug eruption caused by antibiotics. Concerned about allergic reactions, he and his parents did not consent to administrating propofol. The patient's perioperative course was uneventful. The combination of midazolam and dexmedetomidine may be a useful option as substitutes for propofol.
