概括

与健康人相比,慢性疼痛患者在休息和疼痛刺激期间表现出明显的脑电图 (EEG) 模式. 这些EEG测量可以帮助诊断中心敏感性,并预测慢性疼痛的发展.

科学领域:

神经科学是一个神经科学.
疼痛医学医学疼痛医学
生物标志物生物标志物

背景情况:

中央敏感性,神经系统反应的加剧,在慢性疼痛中很常见,但通常是主观评估.
需要客观,直接的神经测量来量化与疼痛相关的神经功能障碍.

研究的目的:

在慢性疼痛患者的客观,校准的疼痛刺激期间,使用脑电图 (EEG) 调查皮质活动.
为了确定潜在的EEG生物标志物用于中央敏感和慢性疼痛.

主要方法:

在8名慢性疼痛患者和8名健康对照中用热和机械刺激记录静止状态和定量感官测试 (QST) 期间的EEG.
分析了静止状态EEG参数 (峰值α频率,功率比) 和在QST期间的变化.
执行了theta频段活动的功能连接性分析.

主要成果:

慢性疼痛患者表现出较低的休息峰值α频率和较高的α/theta和α/β功率比.
在热QST期间,EEG功率比在患者和对照人群中发生了不同的转变.
与对照组相比,患者在QST期间表现出改变的theta-beta频率差异.

结论:

在慢性疼痛患者在休息状态和在急性疼痛刺激期间显示出明显的EEG活动模式.
建议这些EEG测量可以作为中央敏感性和慢性疼痛的诊断生物标志物.
突出了EEG在客观量化疼痛处理异常方面的潜力.

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
