The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were not subjected to radiant heat, and in this group no conclusions were drawn about the efficacy of a hat or a radiant heater. In the 104 infants not subjected to radiant heat, body weight, initial rectal temperature, the application of hat, the environmental temperature, and the duration of exposure while naked were all found to influence measureably the rate of fall in rectal temperature during the first 30 minutes. Gamgee-lined hats should be routinely used to minimise heat loss, especially in small infants exposed at birth, during surgical operations, and during investigations necessitating prolonged exposure.
研究了一种衬有吸水棉的帽子在婴儿出生后最初30分钟内降低直肠温度下降速率的功效。该试验纳入了211名婴儿,是随机、前瞻性且有对照的。107名婴儿暴露于头顶辐射加热器下。其中,只有30名是顺产,因此分析仅限于未接受辐射热的婴儿,并且在该组中未得出关于帽子或辐射加热器功效的结论。在104名未接受辐射热的婴儿中,发现体重、初始直肠温度、帽子的使用、环境温度以及裸体暴露的持续时间均对出生后最初30分钟内直肠温度的下降速率有显著影响。应常规使用衬有吸水棉的帽子以尽量减少热量损失,尤其是对于出生时暴露、手术过程中以及需要长时间暴露的检查中的小婴儿。
