hyperpyrexia

[hī′pərpīrek′sē·ə]
Etymology: Gk, hyper + pyressein, to be feverish
an extremely elevated temperature that sometimes occurs in acute infectious diseases, especially in young children. Malignant hyperpyrexia, characterized by a rapid rise in temperature, tachycardia, tachypnea, sweating, rigidity, and blotchy cyanosis, occasionally occurs in patients undergoing general anesthesia. A high temperature may be reduced by sponging the body with tepid water, by giving a tepid tub bath, or by administering antipyretic medication, such as aspirin or acetaminophen. See also fever. hyperpyretic, adj.

hyperpyrexia

Body temperature above 41.1 C (106 F). Hyperpyrexia calls for urgent treatment to lower the temperature, if permanent brain damage is to be avoided.
