概括

在深度镇静和部分恢复期间的电肌图 (EMG) 沉默可以帮助区分功能性 dystonia (FD) 和异常性 dystonia (ID). 恢复后不同的肌肉激活模式也可能表明FD.

科学领域:

神经学神经学
运动障碍运动障碍
神经生理学神经生理学

背景情况:

功能性 dystonia (FD) 呈现出诊断上的挑战,因为其与异常性 dystonia (ID) 的重叠症状.
目前,没有经过验证的生物标志物可以区分FD和ID.
在麻醉下调查肌肉活动模式可能会揭示区分特征.

研究的目的:

为了探索FD和ID患者之间肌肉活动的差异,在麻醉下使用多电力学图 (PEMG).
确定潜在的神经生理学标记,以区分FD与ID.

主要方法:

10名FD和17名ID患者在普罗波福诱导的镇静和恢复期间接受了连续的PEMG.
在警觉状态,轻度镇静,深度镇静和部分/完全恢复状态期间评估肌肉活动.
从基线对EMG活动模式的变化进行了分析.

主要成果:

在大多数FD患者中,EMG活性在轻度镇静期间 (90%) 持续存在,但在深度镇静 (100%) 和部分恢复 (10%) 期间不存在.
相比之下,EMG活性在很大一部分ID患者中持续存在,即使在深度镇静 (53%) 和部分恢复 (100%) 期间.
在70%的FD患者和6%的ID患者中观察到明显的恢复后肌肉激活模式.

结论:

在深度镇静和部分恢复期间的EMG沉默是FD的潜在神经生理学标志物.
恢复后改变的肌肉激活模式可能成为FD不一致的线索.
在麻醉下PEMG提供了一种有前途的方法来区分FD和ID.

关键词:

Classification of Skeletal Muscle Relaxants

Classification of Skeletal Muscle Relaxants

Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...

Peripherally and Centrally Acting Muscle Relaxants: A Comparison

Peripherally and Centrally Acting Muscle Relaxants: A Comparison

Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic...
