概括
在儿童创伤性脑损伤 (pTBI) 中,对大脑自调节 (CA) 的监测至关重要. 通过压力反应指数 (PRx) 和超过值的时间来衡量CA的损伤,预测严重TBI儿童的结果不佳.
科学领域:
- 儿童重症监护医疗
- 神经临界护理
- 脑血管生理学
背景情况:
- 在血压变化期间,大脑自调节 (CA) 对于维持大脑血流 (CBF) 是至关重要的.
- 这种CA功能障碍增加了二次脑损伤的风险,特别是在儿童创伤性脑损伤 (pTBI) 中.
- 有限的研究存在于pTBI的CA动态.
研究的目的:
- 使用重度TBI儿童的剂量指标来描述PRx障碍.
- 研究PRx指标与患者结果之间的关联.
- 确定PTBI的强有力的结果指标.
主要方法:
- 涉及135名TBI儿童的前性多中心研究 (STARSHIP).
- 超过值的PRx剂量和百分比时间的计算 (0-0.4).
- 统计分析包括回归和倾向得分匹配以评估结果关联.
主要成果:
- 结果较差的患者表现出较高的PRx剂量和超过值的百分比时间.
- 在受伤后的第一个星期,在不良结果组中观察到PRx指标升高.
- 独立预测12个月结果的PRx> 0的百分比时间.
结论:
- PRx指标,特别是超过值的百分比时间,是严重的pTBI结果的强有力的预测指标.
- 压力反应持续时间受损与二分化12个月的结果有着强烈的关联.
- 实时CA监测可以指导严重的pTBI的干预.

Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
