在硫喷妥钠-一氧化二氮复合麻醉下，用针型热敏电阻测量了7例受试者的颈总动脉血温。每个受试者的血温都在口腔温度的0.2[摄氏度]以内。在一名受试者中，呼吸冷却到4摄氏度的空气对颈总动脉血温没有影响。在五分之四的受试者中，有四人通过在面部和前额前部同侧冷敷5-20分钟来降低颈总动脉温度(0.2[度]-0.5[度]℃)。在第五个受试者中，没有变化。这种冷却的可能机制是动脉和颈内静脉之间的热交换，通过共同的面部静脉排出冰冷的结构。面部和额部复温对颈总动脉血温无明显影响。
Common carotid artery blood temperature was measured by means of a needle thermistor in seven subjects under thiopental-nitrous oxide anesthesia. In each subject the blood temperature was within 0.2[degree]C of the oral temperature. In the one subject so tested, the breathing of air chilled to 4[degree]C had no effect on the common carotid blood temperature. In four out of five subjects the common carotid artery temperature was lowered (0.2[degree]-0.5[degree]C) by applying cold packs to the homolateral side of the anterior aspect of the face and forehead for 5-20 minutes. In the fifth subject there was no change. The probable mechanism of this cooling is heat exchange between the artery and the internal jugular vein which drains the chilled structures through the common facial vein. Rewarming the face and forehead had no significant effect on the common carotid blood temperature.
