Abstract:
The authors present a case of malignant hyperthermia. The article discusses the death of a 4-year old boy who appeared to be perfectly healthy and underwent dental treatment under general anesthesia. The procedure went well at the beginning, but suddenly complications developed, such as cardiac rhythm disorders and increased body temperature, subsequently, muscle rigidity appeared. Such symptoms are characteristic for an inherited disease called malignant hyperthermia. Despite professionally performed resuscitation and help of an emergency unit, the patient died.
