Abstract : An automatic control system was used to maintain the body temperature of dogs below 25 C. for 20 hr. Once this low temperature was reached no anesthesia other than hypothermia was required. Blood pressure and pulse rate remained low throughout the cooling periods and as time passed the hematocrit rose, plasma volume fell, pH fell, and venous oxygen saturation fell. Of the 98 dogs cooled in this fashion, 31 survived rewarming. A number of agents and medications have been used in trying to increase the survival rate. Best results were achieved with the most recent technic which features a number of small changes such as deeper anesthesia during induction of hypothermia. Reserpine also may have contributed to a higher survival rate. (Author)
