There is increasing evidence that overheating is a contributing factor for some cot deaths. One hypothesis is that infant thermoregulation is closely related to respiratory control. To test this hypothesis it was necessary to determine the normal pattern of body temperature in the developing infant. A system has been designed and built to record continuously temperature signals from ambient, rectal, and various skin site sensors. Overnight studies were performed on 30 infants aged between 2 and 26 weeks in a hospital ward. Various time and frequency domain analyses of the temperature data have been developed. Analysis of body temperature rhythms has confirmed patterns during sleep which mature with age. In addition a periodic oscillation of body temperature has been found with a cycle of approximately one hour. This oscillation may reflect sleep state and its further study may give an insight into control of infant thermoregulation and the integration of this control with that of breathing and the cardiovascular system.
越来越多的证据表明,过热是导致一些婴儿猝死的一个因素。一种假说认为,婴儿体温调节与呼吸控制密切相关。为了验证这一假说,有必要确定发育中婴儿的正常体温模式。现已设计并构建了一个系统,用于连续记录来自环境、直肠和各种皮肤部位传感器的温度信号。在医院病房对30名年龄在2至26周之间的婴儿进行了夜间研究。已对温度数据进行了各种时域和频域分析。体温节律分析证实了睡眠期间随年龄成熟的模式。此外,还发现体温有大约一小时周期的周期性振荡。这种振荡可能反映睡眠状态,对其进一步研究可能有助于深入了解婴儿体温调节的控制以及这种控制与呼吸和心血管系统控制的整合情况。
