EFFECT OF TEMPERATURE ON PRETERM INFANT SLEEP-WAKE STATE

早产儿面临的众多挑战之一是同步化 活动正常，一天24小时不间断。有令人信服的证据 将体温的昼夜模式与睡眠-觉醒活动联系起来 然而，在成年人中，对早产儿的这种关系知之甚少。 早产儿，由于他们体温调节的限制，需要 用保温箱或其他临床设备加热。几乎没有什么 研究这种加热如何改变睡眠-觉醒模式。这 关系对早产儿适应24小时的影响很大。 小时的昼夜模式。婴儿的节律性和同步能力 照顾方式是婴幼儿与父母互动的显著因素。 基于早产儿认知的孵化器护理管理 婴儿发育期体温生物节律，是一种潜在的干预手段 用于促进睡眠-觉醒模式。这项研究的目的是 研究温度和睡眠-觉醒状态之间的关系 早产和足月妊娠婴儿。研究的具体目的是 住院婴儿体温生物节律发育的检测 早产决定了早产儿睡眠的关系-- 唤醒状态与婴幼儿体温和保温箱温度的比较 体温、生物节律和睡眠-觉醒状态以及婴儿身体和 孵化器温度，并比较体温、生物节律和睡眠- 家庭环境中早产儿和足月儿的觉醒模式。早产 将对婴儿进行纵向和横断面研究，使用 密集的主题设计。孵化器温度与婴儿 腹部皮肤温度将在24小时内使用 将确定婴儿状态的计算机化数据采集系统 通过延时录像。出院后，早产儿和 对照组足月儿将在家庭环境中进行研究， 婴儿腹部皮温(Vitalog)与婴儿睡眠-觉醒状态 将会被测量。体温和睡眠-觉醒状态的周期性 将使用功率谱分析来确定。早产的比较 婴儿跨越时间和横断面将揭示发育变化 在体温和睡眠-清醒状态的生物节律中。的影响 早产对体温和睡眠-觉醒状态发展的影响 模式将在足月儿和早产儿的比较中得到证明。

One of the many challenges facing the preterm infant is synchronizing activities with the normal, 24-hour day. There is convincing evidence linking the day-night patterns of body temperature and sleep-wake activity in adults however, little is known of this relationship in preterm infants. Preterm infants, because of their thermoregulatory limitations, require heating by incubators or other clinical devices. There has been little investigation of how such heating may alter sleep-wake pattern. This relationship is significant to the preterm infant's adaptation to the 24- hour day-night pattern. Infant rhythmicity and the ability to synchronize with caregiving patterns are factors salient to infant-parent interaction. Nursing management of incubators, based on recognition of the preterm infant's developing body temperature biorhythm, is a potential intervention for promoting sleep-wake pattern. The purpose of this research is to examine the relationship between temperature and sleep-wake state in preterm and term gestation infants. Specific aims of the study are to examine the development of temperature biorhythm in hospitalized infants born prematurely, determine the relationship between preterm infant sleep- wake state and both infant body and incubator temperature, and to compare body temperature biorhythm and sleep-wake state and both infant body and incubator temperature, and to compare body temperature biorhythm and sleep- wake patterns in preterm and term infants in the home environment. Preterm infants will be studied longitudinally and cross-sectionally using an intensive within subject design. Incubator temperature and infant abdominal skin temperature will be recorded during a 24-hour period using a computerized data acquisition system while infant state will be determined by lapse-time video recording. Following discharge, preterm infants and a comparison group of term infants will studied in the home environment where infant abdominal skin temperature (Vitalog) and infant sleep-wake state will be measured. Cyclicity in both body temperature and sleep-wake states will be determined using power spectral analysis. Comparisons of preterm infants across time and cross-sectionally will reveal developmental changes in biorhythm of body temperature and sleep-awake states. The effect of premature birth on the development of temperature and sleep-wake state patterns will be evidenced in comparisons of term and preterm infants.
