概括
瞳孔测量和皮肤温度与重症儿童的心率波动相关,这表明它们可能作为自主神经系统失调的生物标志物. 这些发现为监测重症儿科患者提供了新的见解.
科学领域:
- 儿科重症监护医药 儿科重症监护医药
- 自主神经系统生理学 自主神经系统生理学
- 发现生物标志物的发现.
背景情况:
- 自主神经系统 (ANS) 失调在严重疾病中很常见,通常通过心率变化 (HRV) 进行评估.
- 有限的数据存在于其他ANS功能,如瞳孔光反射和温度调节,在重症儿童.
- 这项研究调查了自动瞳孔测量,皮肤温度和HRV在这个人群中的关联.
研究的目的:
- 确定自动瞳孔测量 (神经瞳孔指数,NPI) 和三角形 (中心至外围) 皮肤温度是否与重症儿童的HRV有关.
- 探索在儿科重症监护室 (ICU) 患者中对ANS失调的潜在新床边生物标志物.
主要方法:
- 潜在的观察试点研究,包括儿童ICU患者在机械通风.
- 自动瞳孔测量和皮肤温度在入院后的前72小时内被记录下来.
- 计算了心率变化率 (HRVi),并分析了HRVi和NPi之间的相关性,以及HRVi和三角形皮肤温度.
主要成果:
- 在NPI值 (左和右) 和HRVi (r=0.13,r=0.12;p<0.001) 之间发现了显著的小相关性.
- 德尔塔皮肤温度也显示出与HRVi (r=0.15,p<0.001) 的显著,小的相关性.
- 在对潜在混因素进行调整后,这些关联仍然很重要.
结论:
- 异常的瞳孔光响应和降低的三角形皮肤温度与重症儿童的HRVi较低有关.
- 瞳孔测量和皮肤温度显示出ANS调节失调的生理生物标志物的潜力.
- 这些床边工具可能有助于在重症儿科患者中早期发现自主功能障碍.

Disorders of the Autonomic Nervous System
525
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
