The effect of body temperature on ethanol (ETOH) or ethanol plus pentobarbital (ETOH/PB) lethality was investigated in C57BL/6J mice. Decreasing ambient temperatures from 35-20°C, decreased rectal temperatures from 38-20°C and increased 8-hour survival from 0-93% for ETOH-treated and from 0-100% for ETOH/PB-treated mice. ETOH and ETOH/PB animals with no hypothermia (body temperatures = 38°C) had the highest lethality. Those with body temperatures between 30-32°C had the highest 24-hour survival. These results suggest that controlled hypothermia may be useful in reducing lethality from ethanol or ethanol/combination overdoses.
