在小牛尸体中,使用横向和横向肌肉方法实现四边腰部阻塞 (QLB),注射物扩散到胸部和腰部区域的神经. 需要进一步的临床试验来确认其止痛疗效和安全性.
科学领域:
- 麻醉学 麻醉学
- 人体解剖学 解剖学 解剖学
- 区域麻醉地区麻醉
背景情况:
- 四角腰部块 (QLB) 提供了干部局部区域性镇痛的潜力.
- 研究超声导向的QLB方法对于了解其解剖学可行性至关重要.
研究的目的:
- 评估两种超声指导的四角腰部块方法的可行性:侧面 (QLB-L) 和肌体 (QLB-T).
- 为了评估这些QLB技术在小牛尸体中的头骨后传播和神经染色模式.
主要方法:
- 十只小牛尸体在L1进行双边QLB,使用QLB-L或QLB-T.
- 在超声波指导下,注射使用了iohexol和甲基蓝的混合物.
- 计算机断层扫描和粗体解剖被用来分析注射物传播和神经染色.
主要成果:
- 无论是QLB-L还是QLB-T,都在小牛尸体中证明了解剖学可行性.
- 注射剂从L1到L2连续染色的神经,在胸部区域 (T13到T10) 染色变化.
- 在这两种方法中,染色神经的数量是可比的.
结论:
- 超声导向的侧面和肌肉横向的四角腰部块在小牛尸体上是解剖学上可行的.
- 观察到的注射剂传播表明潜在的覆盖范围是腹壁的目标.
- 需要进行临床试验,以确定QLB在患者中的止痛效果和安全性.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
