To evaluate the effect of fluctuations in environment and body temperatures on preterm infants, we recorded these variables in very immature newborn infants (birth weight less than 1000 gm) cared for in double-walled incubators (Air-Shields model C-100 and Ohio model IC). Both incubators maintained environmental temperatures corresponding overall to the set point, despite incubator openings. Under skin temperature servocontrol, however, environmental temperature fluctuations were greater than 2 degrees C even in strictly controlled conditions. The pattern of incubator temperature fluctuations depended on the set point rather than on the type of incubator (conventionally heated or heated by warm air blown between the double walls). The long-term clinical significance of the incubator temperature variability remains to be determined; the choice between air and skin servocontrolling should depend in part on the need for environmental stability.
为评估环境温度和体温波动对早产儿的影响，我们在使用双层壁暖箱（Air-Shields C-100型和俄亥俄IC型）护理的极低体重新生儿（出生体重小于1000克）中记录了这些变量。尽管暖箱有开口，但两个暖箱的环境温度总体上都保持在设定点。然而，在皮肤温度伺服控制下，即使在严格控制的条件下，环境温度波动仍大于2摄氏度。暖箱温度波动的模式取决于设定点，而不是暖箱类型（传统加热或通过双层壁之间吹送的暖空气加热）。暖箱温度变化的长期临床意义尚待确定；空气和皮肤伺服控制之间的选择部分应取决于对环境稳定性的需求。
