概括
在肩部外科手术患者中,缓慢的10分钟输注间阻塞剂显著减少了神经阻塞的发生率,从83%降至7%. 这种方法可以保持肺功能,并提供与单次阻塞相比的24小时疼痛缓解.
科学领域:
- 麻醉学 麻醉学
- 区域麻醉地区麻醉
- 胸部外科手术 胸部外科手术
背景情况:
- 跨块提供有效的肩部麻醉和止痛.
- 侧神经是一种常见的副作用,在呼吸系统受损的患者中可能是严重的.
- 一种缓慢的输液技术被假设可以减轻神经阻塞的发生.
研究的目的:
- 为了调查缓慢的,10分钟的输液中干阻塞是否减少了与快速的,单次注射相比,完全的神经阻塞的发生率.
- 评估缓慢输液技术对肺功能 (FEV1和FVC) 和术后止痛的影响.
主要方法:
- 一项随机对照试验,涉及83名接受关节镜肩部手术的患者.
- 患者被随机分配到单次注射间内 (1分钟输注) 或慢速输注 (10分钟) 使用注射器.
- 脑膜神经阻塞通过腹膜外流评估,记录了肺功能测试 (FEV1,FVC) 和疼痛评分 (NRS).
主要成果:
- 缓慢输液组与单次注射组 (83%) 相比,完全神经阻塞的发生率显著降低 (7%).
- 用FEV1和FVC测量的肺功能在阻塞后30分钟的缓慢输液组中得到更好的保存.
- 两个组的24小时术后疼痛评分和吗啡消耗在两组之间都相似,表明了可比的止痛效果.
结论:
- 连续10分钟内进行的间内阻塞可以显著降低肩膀手术患者中神经阻塞的发生率.
- 这种缓慢的输液技术保持了24小时有效的术后止痛,同时与标准的单次注射方法相比,保持了呼吸功能.

01:19Depolarizing Blockers: Pharmocokinetics
556
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.1K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
