title: [Anesthetic management of two patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS)].
abstract: MELAS is a type of the mitochondrial myopathy characterized by elevation of pyruvate and lactate levels in both the blood and cerebrospinal fluid. This syndrome frequently accompanies cerebral infarction like symptoms. Recently, we experienced two patients for anesthesia with MELAS (both 11-year-old girls). V-P shunt construction and IVH reservoir implantation were conducted, respectively. Anesthesia was induced with fentanyl and midazolam, and vecuronium was used to facilitate tracheal intubation. Volatile anesthetic was avoided, and anesthesia was maintained with fentanyl, midazolam, and nitrous oxide. Arterial blood gases and pH were frequently checked, and acetated electrolyte solution was infused mainly during surgery. No complications occurred during anesthesia in both patients. In the anesthetic management for MELAS, measures to prevent malignant hyperthermia must also be considered.
