概括
在下肢整形手术患者中,静脉注射德克斯梅托米丁显著延长了感觉阻塞的持续时间和增强了术后止痛. 这种方法减少了术后疼痛药的需要,并减少了副作用.
科学领域:
- 麻醉学
- 药理学
背景情况:
- 在下肢整形手术中, 脊柱麻醉是常见的.
- 优化感官阻断的持续时间和术后疼痛管理对于患者的康复至关重要.
研究的目的:
- 评估静脉注射 (IV) 德克斯梅托米丁对脊髓麻醉期间感觉阻断的持续时间和术后止痛的影响.
- 在接受下肢整形手术的患者中评估IV德克斯梅托米丁的安全性和有效性.
主要方法:
- 这是一项前性,随机,双盲,受控试验,涉及58名成年患者 (ASA I/ II).
- 在整个手术过程中,干预组接受了静脉注射的德克斯梅多米丁 (0. 5 毫克/ 千克-1 针,随后输入0. 5 毫克/ 千克-1. 1 小时).
- 对照组接受了没有德克斯梅德托米丁的标准治疗.
主要成果:
- 输入式德克斯梅托米丁显著延长了感觉阻断的持续时间 (137. 03 ± 25. 02分钟与79. 45 ± 11. 27分钟相比; p=0.000).
- 术后疼痛评分 (VAS) 在4小时和24小时的德克斯梅托米丁组较低 (p< 0. 001).

Local Anesthetics: Clinical Application as Spinal Anesthesia
772
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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
557
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.

Depolarizing Blockers: Pharmocokinetics
377
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...

Local Anesthetics: Clinical Application as Epidural Anesthesia
498
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Parenteral Anesthetics: Overview
196
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Depolarizing Blockers: Mechanism of Action
1.8K
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...
