Radio Frequency (13.56 MHz) Energy Enhances Rewarming from Mild Hypothermia.

摘要

The rate of warming after hypothermia depends on the method of rewarming. This study compared the effectiveness of radio frequency (RF) energy against hot (41 C) water immersion (HW) and an insulated cocoon (IC) for rewarming hypothermic men. Six men fasted overnight and were rewarmed for one hour after attaining a 0.5 reduction in rectal temperature (Tre). Tre and esophageal temperature (Tes) were recorded every 5 minutes with non-metallic thermal probes. The baseline value for Tre and Tes just prior to rewarming was subtracted from each 5 minute Tre and Tes during rewarming to delta Tre and delta Tres. The twelve delta Tes values were average for each individual and compared using ANOVA. The present study shows the superiority of radio frequency energy for rewarming mildly hypothermic men.
