Abstract
The thermal balance of 13 term infants was measured in a closed-circuit metabolism chamber. Each was studied naked, then with a gamgee-lined hat, and finally with a 'cummerbund' made of a similar material and of similar dimensions. At 27 degrees C the oxygen consumption of the 'hatted' babies was only 85% and the total heat loss 75% of the values measured with the infants naked. The cummerbund offered no detectable benefit. An additional 10 infants were studied while wearing a tubegauze hat at environmental temperatures of 28.5 (+/- 0.5) degrees C. This type of hat gave no measurable thermal protection. It is concluded that a substantial reduction of thermal stress in adverse environments can be achieved simply and clearly by adequately covering the vault of the skull.
摘要
在一个闭路代谢室中测量了13名足月儿的热平衡。每个婴儿先裸体进行研究，然后戴上衬有吸水棉的帽子，最后戴上由类似材料制成且尺寸相似的“腹带”进行研究。在27摄氏度时，戴帽子婴儿的耗氧量仅为裸体婴儿测量值的85%，总热量损失为75%。腹带没有带来可检测到的益处。另外10名婴儿在环境温度为28.5（±0.5）摄氏度时戴着管状纱布帽进行了研究。这种类型的帽子没有提供可测量的热保护。结论是，在不利环境中，通过充分覆盖颅顶可以简单而明显地大幅降低热应激。
