Defining a thermoneutral environment remains difficult because thermoneutrality depends on both physical and physiological factors. A servocontrolled skin temperature derivative (SCS) heating device has been designed to control the thermal environment in closed incubators without the necessity of setting an air or skin reference temperature. The thermal environment obtained with the SCS program is controlled only by the neonate's skin temperature changes. For each neonate, the program allows the attainment of a specific individual thermal equilibrium (Teq). Although the mean value of the thermal equilibrium level measured on 29 neonates does not differ significantly from the neutral air temperature defined from the charts of other researchers, individual values of Teq differed greatly among neonates of similar birthweight and postnatal age. When compared with on/off heating programs, the SCS system permits greater quiet sleep occurrence and seems to provide an optimal thermal environment. The results suggest that the skin temperature derivative heating program takes into account both the ambient and physiological factors affecting body temperature regulation of each neonate.
定义一个热中性环境仍然很困难,因为热中性取决于物理和生理因素。一种伺服控制的皮肤温度导数(SCS)加热装置已被设计用于控制封闭培养箱中的热环境,而无需设定空气或皮肤参考温度。通过SCS程序获得的热环境仅由新生儿的皮肤温度变化控制。对于每个新生儿,该程序允许达到特定的个体热平衡(Teq)。尽管在29名新生儿身上测量的热平衡水平的平均值与其他研究人员图表中定义的中性空气温度没有显著差异,但相似出生体重和出生后年龄的新生儿的Teq个体值差异很大。与开/关加热程序相比,SCS系统允许更多安静睡眠的发生,似乎提供了一个最佳的热环境。结果表明,皮肤温度导数加热程序考虑了影响每个新生儿体温调节的环境和生理因素。
