概括
呼吸道肌肉训练 (RMT) 在脊髓肌肉缩 (SMA) 患者中显示出小益处. 较高的训练量与更大的吸气压力增加相关,这表明SMA患者有改善呼吸功能的潜力.
科学领域:
- 神经学 神经学
- 肺部病理学 肺部病理学
- 康复医学 康复医学 康复医学
背景情况:
- 脊椎肌肉缩 (SMA) 是一种进展性神经肌肉疾病,其特征是显著的呼吸肌肉衰弱.
- 改善SMA患者呼吸功能的有效干预措施对于提高生活质量和预后至关重要.
研究的目的:
- 评估呼吸肌训练 (RMT) 在患有SMA和同时出现呼吸肌弱的个体中的有效性和可行性.
- 探索训练量与一年内最大吸气压 (PImax) 的改善之间的关系.
主要方法:
- 一项为期4个月的单盲随机对照试验 (RCT) 涉及30名参与者 (≥8岁) 患有SMA类型1-4和呼吸系统衰弱.
- 训练组在30%的最大压力下接受了RMT,并根据感知到的劳动力进行调整;对照组最初接受了10%的RMT.
- 主要结局是RCT后PImax的组间差异;次要分析检查了训练量与PImax增加的关联.
主要成果:
- 在四个月后,在两组之间观察到PImax的小,非统计学上显著的差异 (平均差异:6.8cmH2O).
- 在一年内,训练量 (训练次数x强度) 和PImax增加之间发现了显著的关联 (R2 = 0.531).
- 该研究不足以检测出统计学上显著的群体间差异.
结论:
- 在SMA患者中,RMT对PImax表现出适度的影响,安全性得到证实.
- 对于RMT的可行性,需要进一步优化,以便在这个人群中广泛临床应用.
- 训练量似乎是实现SMA呼吸系统改善的关键因素.

Skeletal Muscle Relaxants: Therapeutic Uses
891
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Assessment of Airway, Skin Color, and Use of Accessory Muscles
1.6K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
