概括
与标准外围注射技术相比,持续刺穿外围注射 (DPE) 技术不会降低用于产痛的罗皮瓦卡因有效剂量. 这项研究没有发现与DPE配合的罗皮瓦卡因具有显著的节约剂量效应.
科学领域:
- 麻醉学 麻醉学
- 产科 产科 产科 产科 产科
- 药理学 药理学是指药理学的学科.
背景情况:
- 长期刺穿外周 (DPE) 技术与标准外周方法相比,提供更快的分娩止痛开始和更好的质量.
- 之前的研究表明,DPE在90% (ED90) 的患者中,在分娩期间将布皮瓦卡因的有效剂量降低了35%.
- 布皮瓦卡因和罗皮瓦卡因之间的药理差异,以及DPE对罗皮瓦卡因剂量的影响,仍未得到研究.
研究的目的:
- 为了确定50% (ED50) 和ED90的罗皮瓦卡因用于分娩止痛的有效剂量.
- 为了比较DPE和标准外围注射技术之间的罗皮瓦卡因剂量要求.
主要方法:
- 随机试验涉及分娩妇女,通过DPE或标准外围注射技术接受五种罗皮瓦卡因 (12-24毫克) 剂量之一.
- 有效止痛被定义为NRS疼痛评分<3在20分钟后给药.
- 使用探针分析计算的ED50和ED90值;用于比较的相对中位强度比.
主要成果:
- 罗皮瓦卡因的ED50为18.6毫克 (DPE) 与19.2毫克 (标准外周支架) 相比.
- 罗皮瓦卡因的ED90为30.5毫克 (DPE) 与31.1毫克 (标准外周支架) 相比.

Local Anesthetics: Clinical Application as Epidural Anesthesia
687
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...

Local Anesthetics: Clinical Application as Spinal Anesthesia
1.3K
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
1.2K
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.

Parenteral Anesthetics: Overview
602
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.

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
1.9K
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...

Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.4K
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...
