(1) Dantrolene is used to treat malignant hyperthermia , a condition that bears striking clinical resemblance to NMS.(2) Thyroid storm is a rare disorder characterized by hypertension, hyperthermia , and multiple systems involvement.(3) Furthermore, the use of hypothermia blankets is associated with large temperature fluctuations and rebound hyperthermia .(4) Extracorporeal whole body hyperthermia has been utilized for a number of clinical conditions.(5) In some cases, hyperthermia (high body temperature) and convulsions can lead to death, according to NIDA.(6) Respiratory circuit function recorded in the ventral respiratory group is particularly susceptible to hyperthermic stress.(7) She had become increasingly hyperthermic throughout the night.(8) Heart rate, cardiac output, and minute ventilation increase under hyperthermic conditions, while visceral perfusion decreases.(9) This is well below the temperatures inducing hyperthermic effects.(10) Based on these findings, irrigation fluids should approximate body temperature to avoid hypothermic or hyperthermic injury.
