title: Reduced temperature afterdrop in rhesus monkeys with radio frequency rewarming.
abstract: Rhesus monkeys were anesthetized and rendered hypothermic by icewater immersion. Rewarming by radio frequency (RF) energy at 13.56 MHz or by a surgical heating pad was initiated either immediately after removal from the icewater or after a delay of 20-26 min. Rectal temperature (Tre) was monitored during each experiment, and RF energy, initially applied at a specific absorption rate (SAR) of 10 W.kg-1, was able to raise Tre an average of 3 degrees C in 20 min. For an equivalent period of rewarming with the heating pad, Tre had not yet recovered from the immersion-induced afterdrop. It is concluded that RF rewarming offers a special advantage when applied to the treatment of immersion hypothermia.
