Three groups of adult patients were anaesthetized for elective intra-abdominal surgery. In one group, patients were ventilated with dry anaesthetic gases, and these patients all lost heat. In the second group humidification was used to annul respiratory heat exchange, and these patients lost heat initially but tended to regain heat during anaesthesia. The third group, in addition to humidification, had surface insulation and all these patients gained heat. It is suggested that conservative methods which negate heat loss are able to prevent hypothermia by the retention of metabolically produced heat.
三组成年患者接受麻醉以进行择期腹部手术。在一组中，患者使用干燥的麻醉气体进行通气，这些患者均出现体温下降。在第二组中，采用加湿措施以消除呼吸热交换，这些患者起初体温下降，但在麻醉过程中倾向于恢复体温。第三组除了采用加湿措施外，还进行体表保温，所有这些患者体温上升。研究表明，消除热量散失的保守方法能够通过保留代谢产生的热量来预防体温过低。
