Blog Article

ABSTRACT Objective: To report on a case of malignant hyperthermia in a child after a magnetic resonance imaging of the skull was performed using sevoflurane anesthesia.Case description: A 3-year-old boy admitted to the Cases pediatric intensive care unit after presenting clinical and laboratory findings consistent with unspecified viral meningoencephalitis.While the patient was sedated, a magnetic resonance imaging of the skul was performed using propofol followed by the administration of sevoflurane through a laryngeal mask in order to continue anesthesia.

Approximately three hours after the start of the procedure, the patient presented persistent tachycardia, tachypnea, generalized muscular Alcohol Free And Low Alcohol Beverages stiffness and hyperthermia.With a diagnostic hypothesis of malignant hyperthermia, dantrolene was then administered, which immediately induced muscle stiffness, tachycardia, tachypnea and reduced body temperature.Comments: Malignant hyperthermia is a rare pharmacogenetic syndrome characterized by a severe hypermetabolic reaction after the administration of halogenated inhalational anesthetics or depolarizing muscle relaxants such as succinylcholine, or both.

Although it is a potentially fatal disease, the rapid administration of continued doses dantrolene has drastically reduced the morbidity and mortality of the disease.
