概括
用于激光辅助喉微手术的最佳mivacurium输液速率为8μg kg-1分钟-1.1. 这种速率确保了有利的外科条件,需要最小的补充剂量和较少的不良反应.
科学领域:
- 麻醉学 麻醉学
- 药理学 药理学是指药理学的学科.
- 手术瘤学手术瘤学
背景情况:
- 米瓦是一种短效,非去极化的神经肌肉阻断剂.
- 它用于横口激光微手术期间的声带肌肉松.
研究的目的:
- 为了确定mivacurium在横口激光微手术中的最佳剂量.
- 使用闭环目标控制输液系统来比较输液速率.
主要方法:
- 一项前性随机临床试验,涉及60名接受激光辅助喉微手术的患者.
- 患者接受的诱导剂量为0.2毫克-1千克.
- 三组接受了不同的输液速率:6,7或8μg/kg-1分钟-1.1.
主要成果:
- 两组之间没有观察到发病时间,无反应时间或恢复指数 (RI) 的显著差异.
- 与6μg kg-1 min-1 (15名患者) 和7μg kg-1 min-1 (10名患者) 组相比,在8μg kg-1 min-1组 (3名患者) 需要更少的补充米瓦剂量.
- 较长的无反应时间 (>5.68分钟) 与减少的米瓦补充剂相关,并与无反应时间和总米瓦剂量相关.
结论:
- 在激光辅助喉微手术中,为mivacurium的输液速率为8μg kg -1 min -1是最佳的.
- 这种速度提供了有利的外科外科条件,包括没有非自愿的声带运动.
- 它还减少了对补充剂量的需求,并减少了不良反应.

01:19Depolarizing Blockers: Pharmocokinetics
305
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...

462
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...
