摘要

本研究的目的是描述脊神经的解剖结构,特别是最后一段胸神经(T13)和第一至第三段腰神经(L1至L3),以便安全地在绵羊身上进行准确的近端椎旁阻滞(PPVB)。本研究分为两个阶段。在第1阶段,解剖7只羊尸体,以确定T13和L1至L3脊神经的路径和相关解剖标志。在第二阶段,2只健康的绵羊通过PPVB入路,双侧每半胸腰区注射0.35 mL/kg体重(每条神经0.088 mL/kg体重)的染料利多卡因溶液(50:50),然后评估15分钟利多卡因全身和局部作用的征象。安乐死后,解剖浸润区域以评估染料的扩散情况。成功的神经染色(长度> 2cm),宏观证据显示神经内/血管内注射,并扩散到硬膜外间隙和腹腔。在第1阶段,所有神经的每个分支都很容易被识别和定位,使用棘突突的尾端和各自椎骨横突的外侧边缘。在肋腹神经(T13)、髂腹下神经(L1)和髂腹股沟神经(L2)之间观察到重叠。在第二阶段,所有神经在距注射部位至少2cm处染色。未见染料扩散至硬膜外腔或腹腔。综上所述,利用绵羊特异性解剖标志,PPVB提供了注射的染料利多卡因溶液的准确神经周围分布,可以实现临床侧腹镇痛。

Anatomical landmarks for a proximal paravertebral thoracolumbar block in sheep: Cadaver and in-vivo study.

The objective of this study was to describe the anatomy of the spinal nerves, specifically the last thoracic nerve (T13) and the first to third lumbar nerves (L1 to L3), in order to safely carry out an accurate proximal paravertebral block (PPVB) in sheep. This study consisted of 2 phases. In Phase 1, 7 sheep cadavers were dissected to identify the path and relevant anatomical landmarks of spinal nerves T13 and L1 to L3. In Phase 2, 2 healthy sheep received bilateral injections of 0.35 mL/kg body weight (BW) for each hemithoracolumbar area (0.088 mL/kg BW per nerve) of a dye-lidocaine solution (50:50) using a PPVB approach and then assessed for 15 min for signs of systemic and local effects of lidocaine. After euthanasia, the infiltrated area was dissected to assess the spread of the dye. Successful nerve staining (> 2 cm in length), macroscopic evidence of intraneural/intravascular injection, and spread to the epidural space and the abdominal cavity were recorded. In Phase 1, each branch of all nerves was easily identified and located using the caudal aspect of the spinous apophysis and the lateral edge of the transverse process of the respective vertebrae. An overlap was observed between the costoabdominal (T13), the iliohypogastric (L1), and ilioinguinal (L2) nerves. In Phase 2, all nerves were stained at least 2 cm from the injection site. There was no diffusion of the dye into the epidural space or abdominal cavity. In conclusion, using the anatomical landmarks described specifically for sheep, the PPVB provided accurate perineural distribution of the injected dye-lidocaine solution, which could result in clinical analgesia of the flank.
