This serious condition produces a variety of symptoms such as a fast heartbeat and breathing rate, stiff muscles, changes in the acidity of the body and rhythm of the heart as well as high blood pressure. The reaction requires emergency treatment including oxygen, cooling the body, controlling its acidity, stopping the anaesthetic and giving Dantrium Intravenous. This injection is given to you by a doctor immediately when malignant hyperthermia is recognised.
