概括
利多卡因的前给药没有改变罗库.
科学领域:
- 麻醉学 麻醉学
- 药理学 药理学是指药理学的学科.
背景情况:
- 已知利多卡因可在全身麻醉下缩短vecuronium的发作时间.
- 以前的研究表明,利多卡因不会影响罗库的发病,可能是由于使用的罗库剂量较高.
- 这项研究研究了较低的罗库剂量 (0.4毫克/千克) 与利多卡因 (lidocaine) 的作用.
研究的目的:
- 为了评估1.5毫克/千克利多卡因对0.4毫克/千克罗库的神经肌肉阻塞特征的影响.
- 评估对发病时间的影响,50%和100%的抑郁时间,以及作用的持续时间.
主要方法:
- 一项随机,双盲,安慰剂控制的研究与60名成年患者进行.
- 在0.4mg/kg的罗库注射之前,患者接受了1.5mg/kg的利多卡因 (利多卡因组) 或盐水安慰剂 (安慰剂组).
- 用普罗波福和雷米芬坦尼尔在全身麻醉下使用四列列车刺激来监测神经肌肉阻塞.
主要成果:
- 在利多卡因和安慰剂组 (368.0与314.8秒,p=0.24) 之间没有观察到罗库的发病时间有显著差异.
- 利多卡因的使用也没有显著影响50%的抑郁时间,100%的抑郁时间或罗库的作用持续时间.
- 统计分析显示,这两个组之间的这些参数没有显著差异.
结论:
- 1.5毫克/公斤利多卡因的预先使用不会显著改变0.4毫克/公斤罗库的发病时间,神经肌肉阻塞强度或作用持续时间.
- 这些发现表明,利多卡因对神经肌肉阻断剂的影响可能是特定于某些药物,如Vecuronium.
- 进一步的研究可以探索不同的剂量或患者群体.

01:19Depolarizing Blockers: Pharmocokinetics
301
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
349
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.

01:28Depolarizing Blockers: Mechanism of Action
1.1K
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

01:17Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action
1.4K
Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
570
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

01:31Skeletal Muscle Relaxants: Therapeutic Uses
460
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...
