概括
早产婴儿的唾液皮质醇水平与新生儿压力度量表 (NISS) 不相关. 然而,早出生 (<28周妊娠) 的婴儿表现出更高的皮质醇水平和较低的NISS分数,表明更大的压力暴露.
科学领域:
- 新生儿科学 新生儿科学
- 儿科内分泌学 儿科内分泌学
- 压力生理学 压力生理学
背景情况:
- 在新生儿重症监护室 (NICU) 中,早产婴儿经历了重要的环境压力因素.
- 评估婴儿压力对于优化护理和发育结果至关重要.
- 唾液皮质醇是生理应激反应的生物标志物.
研究的目的:
- 为了研究唾液皮质醇水平与新生儿压力表 (NISS) 在早产婴儿生命的第一个星期的分数之间的相关性.
- 分析第一周NISS分数和皮质醇水平的变化.
- 为了确定皮质醇水平是否与妊娠年龄有关.
主要方法:
- 包括38名早产婴儿 (出生体重<1250克和/或妊娠年龄<29周).
- 在0-3 (早期) 和4-7 (晚期) 日收集的唾液样本用于皮质醇测量.
- 每次唾液采集前六小时的评估NISS评分.
主要成果:
- 在NISS得分和唾液皮质醇水平之间没有发现显著的相关性.
- 怀孕28周以下的婴儿与28周以上的婴儿相比,表现出更高的皮质醇水平 (p=0.0068).
- 在NISS得分和妊娠年龄之间观察到显著的反向关系 (p=0.04).
结论:
- 在极度早产婴儿 (<28周妊娠期) 中,皮质醇水平升高与NISS分数没有直接相关.
- NISS分数与妊娠年龄相反,这表明较小的婴儿更容易接触到医疗干预措施.
- 这些发现强调了早产新生儿的复杂应激反应,以及需要个性化的护理策略.

Introduction to Stress and Lifestyle
86
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Physiological Foundation of Stress
48
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.
