- 麻醉学 麻醉学
- 药理学 药理学是指药理学的学科.
背景情况:
- 第三个牙的提取是一种常见的外科手术程序,通常与严重的术后疼痛有关.
- 有效的疼痛管理对于第三手术后的患者康复和满意度至关重要.
- 脂质体布皮瓦卡因 (LB) 是一种长效局部麻醉剂,可以提供长时间的止痛.
研究的目的:
- 为了评估与安慰剂相比,脂质体布皮瓦卡因 (LB) 的止痛效果和安全性,在接受双边第三骨提取的患者中.
- 在手术后96小时内使用数值评分表 (NRS) 评估疼痛严重程度.
- 为了确定与LB相关的不良事件的发生率,在这个患者群体中.
主要方法:
- 第三阶段,双盲,安慰剂对照研究,涉及接受双边第三骨提取的受试者.
- 随机选择受试者通过透接受脂质体布皮瓦卡因 (133 mg/10 mL) 或安慰剂.
- 使用数值评分尺度 (NRS) 评估疼痛严重程度,并将曲线下的累积面积 (AUC) 作为主要疗效指标 (NRS0-48的AUC).
主要成果:
- 在每项方案的人群中,脂质体布皮瓦卡因与安慰剂相比,累积疼痛得分 (NRS0-48的AUC) 显著降低 (120.8对183.3,P = .023).
- 然而,在初级疗效群体中,LB和安慰剂之间的NRS0-48AUC的差异在统计学上并不显著 (172.3与194.7,P = .227).
- 脂质体布皮瓦卡因和安慰剂组之间的安全性概况相似,不良事件没有显著差异.

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
356
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.

Local Anesthetics: Clinical Application as Epidural Anesthesia
409
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
578
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 Surface, Infiltration, and Conduction Block Anesthesia
955
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: Common Agents and Their Applications
403
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
