摘　　要：目的：探讨人工气道吸入气体温度对极低体重儿核心体温的影响。方法：将我院符合入组标准的45例建立人工气道的极低体重儿随机等分为3组,A组吸入气体温度设置为36.5-37.3℃,B组吸入气体温度设置为34.5-35℃,C组吸入气体温度设置为38.5-39℃。均以感应器测定的到达患儿口边的气体温度为设定温度,每2 h测量3组患儿体温（肛温）1次并记录。结果：A组患儿核心温度维持在中性温度,B组患儿核心温度低于中性温度,C组则高于中性温度。结论：极低体重儿建立人工气道时将吸入气体温度调到36.5-37.3℃可使极低体重儿的核心体温度维持在中性温度,同时降低耗氧量、减少蒸发散热,降低新陈代谢,减少并发症。Objective：To study the effects of the temperature of inspiratory gas with artificial airway on core temperature in very low birth weight infants. Methods：45 very low birth weight infants with artificial airway were randomly divided into three groups according to the temperature of inspiratory gas. The temperature of inspiratory gas was 36. 5-37. 3℃ in the group A,34. 5-35℃ in the group B,and 38. 5-39℃ in the group C. The gas temperature at the side of patents′mouth as the setting temperature was dicided by the inductor. The rectal temperature of the infants were recorded every 2 hours. Results：The core temperature in the infant was maintained at neutral temperature when the setting temperature was 36. 5-37. 3℃（group A）（P〈0. 05）. The core tem-perature was lower than neutral temperature when the setting temperature was 34. 5-35℃（group B）. The core temperature was higher than neutral temper-ature when the setting temperature was 38. 5-39 ℃（group C）. Conclusion：The core temperature in very low birth weight infant with artificial airway could be maintained at neutral temperature when the temperature of inspiratory gas was 36. 5-37. 3 ℃. At the same time,It could decrease oxygen consumption, the loss of evaporative heat,metabolism,and reduce complication.
