概括

在创伤性脑损伤 (TBI) 患者中,有针对性的温度管理 (TTM) 到正常热量降低了内压力,但没有改善整体的大脑氧化. 一个子组经历了大脑氧化减少,与二氧化碳水平的变化有关.

科学领域:

神经科学是一个神经科学.
关键护理医学关键护理医学
生理学生理学生理学

背景情况:

针对性温度管理 (TTM) 到正常热量是创伤性脑损伤 (TBI) 患者的常见干预措施.
了解TTM在TBI中的生理后果对于优化患者护理至关重要.
多模式监测对于评估TBI患者的大脑氧化和内压力至关重要.

研究的目的:

在TBI患者中 (GCS≤12) 通过使用多模式监测来研究TTM对正常热量的生理影响.
为了确定TBI患者在TTM期间大脑氧化恶化时是否发生生理参数的变化.

主要方法:

对102名TBI患者进行回顾性研究,持续监测内压力 (ICP) 和脑氧张力 (PbtO2).
包括非连续的动脉二氧化碳 (PaCO2) 和氧气 (PaO2) 压力,以及核心体温 (Tc).
在39名患者的正常热度过渡前8小时和过渡后,对生理参数进行比较.

主要成果:

常温降低了ICP和核心体温,但没有显著改变整体PbtO2.
一个由18名患者组成的小组在正常热量期间经历了PbtO2的下降.
这种PbtO2的减少与ICP和温度校正的PaCO2.2的减少有关.

结论:

从TTM到正常热量可能导致PbtO2在TBI患者的一个子集下降.
这一发现表明与温度变化相关的潜在隐秘高通风.
在TBI的未来TTM协议中应考虑通风的pH-stat校正.

Decreased Body Temperature

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...

Traumatic Brain Injury l: Introduction

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.
