概括
勃起器脊柱平面块 (ESPB) 在活体中广泛传播,到达背部肌肉和肋间间空间. 然而,单方面ESPB并没有显著降低肝瘤射频切除后的疼痛.
科学领域:
- 麻醉学 麻醉学
- 放射学 放射学是一门学科.
- 疼痛管理 疼痛管理
背景情况:
- 在活体受试者中,勃起器脊柱平面块 (ESPB) 的传播模式需要进一步调查.
- 了解ESPB的传播对于优化其在计算机断层扫描指导的肝脏瘤射频切除等程序中的使用至关重要.
研究的目的:
- 为了研究ESPB在接受CT导向放射频移除肝脏瘤的患者中的局部麻醉或盐水传播模式.
- 为了将药物传播与患者特征相关联,并评估其对疼痛强度和吗啡消费的影响.
主要方法:
- 这是一项双盲随机对照试验,涉及30名患者.
- 患者被随机分配,接受局部麻醉和对比剂的ESPB或用盐水和对比剂的假阻塞.
- 通过CT评估药物传播,以及疼痛强度和吗啡消耗.
主要成果:
- ESPB 连续地从头骨尾部扩散到背部直立脊柱肌 (中位数 9 层) 和肋间间 (中位数 4 层).
- 在90%的患者 (中位数为3个水平) 中发生了椎间盘扩散,在36.7%的患者 (中位数为0个水平) 中发生了外周扩散.
- 尾扩散与背部肌肉厚度有负相关性;女性比男性有更大的肋间扩散. 两组之间没有发现疼痛或吗啡使用的显著差异.
结论:
- 这项研究为ESPB在活体受试者中药物传播模式提供了宝贵的见解.
- 一个单边的ESPB证明,在肝脏瘤的射频移除中,镇痛功效不足.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
567
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...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
403
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...
