概括
经过修改的纵向中间椎阻塞 (MU) 与基准 (LM) 和超声指导 (US) 方法相比,在关节骨手术中提供了优越的关节神经阻塞. 然而,MU方法与腹膜的发病率较高有关.
科学领域:
- 麻醉学 麻醉学
- 区域麻醉地区麻醉
- 手术手术手术手术手术手术手术手术手术手术
背景情况:
- 表面交积块 (SCPB) 是关节骨外科手术的标准,由于关节骨上神经 (SN) 的内化.
- 有限的数据存在,比较不同的SCPB技术用于SN覆盖和神经安全.
- 新型修改的纵向中间宫结块 (MU) 需要进一步评估.
研究的目的:
- 为了比较MU方法的有效性与基于地标 (LM) 和超声波引导 (US) 的中间SCPB技术.
- 在程序后20分钟评估SN封锁的成功.
- 评估腹膜作为一个关键的安全结果.
主要方法:
- 这是一项随机,双盲,受控试验,涉及45名健康志愿者.
- 进行了三种右侧SCPB方法:LM,US和MU.
- 对于所有阻塞,使用了10毫升0.5%的罗皮瓦卡因,评估了SN阻塞和隔膜外流.
主要成果:
- 在20分钟内,SN封锁的成功率为0% (LM),40.0% (US) 和73.33% (MU) (p < 0.001).
- 在静静呼吸期间发生的完全腹膜发生在0% (LM),0% (US) 和33.33% (MU) (p = 0.005).
- 两组之间没有观察到氧和或并发症率的显著差异.
结论:
- 与LM和US技术相比,MU方法在20分钟内显示出优异的SN感官阻断.
- 这种MU技术与腹膜的发病率较高有关.
- 需要在外科患者群体中进行进一步的研究来验证这些发现.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.6K
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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.6K
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.

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

1.5K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
