摘要

这项前瞻性解剖学研究的目的是在绵羊尸体中建立一种超声引导的腰椎四头肌(QL)平面技术。共纳入 13 具体重小于 117 千克的绵羊尸体。在第一阶段,一具尸体进行了解剖,两具尸体进行了三维计算机断层扫描重建,以对胸腰部进行解剖评估。在第二阶段,两具尸体被用来比较两种针对 QL 平面的超声波技术:横向方法(LQL)下的 QL 肌肉外侧超声波和纵向方法(TQL)下的 QL 和腰肌之间的跨肌肉超声波。对于 LQL,参照物是第一腰椎横突,而对于 TQL,参照物是第一腰椎和第二腰椎之间的横向区域。针头在平面内向每种技术的特定目标推进,使用 0.4 毫升/千克的染料利多卡因溶液共进行了四次注射。在第三阶段,10 具尸体接受了双侧 LQL 注射(n = 20)。然后解剖所有尸体以评估染料的扩散情况。在第 2 阶段,注射 LQL 后,未在不希望的位置观察到染料;但注射 TQL 后,在腹膜后间隙(1/2)观察到染料。在第 3 阶段,分别有 80%、95%、100%、45% 和 35% 的注射对第 13 胸神经、第一、第二、第三腰神经和交感干节段进行了染色。总之,LQL 技术是可行的,可以对绵羊尸体中支配颅腹的脊神经进行染色。有必要在活体动物中进行进一步研究。

Ultrasound-guided quadratus lumborum block in sheep: A cadaveric study.

This prospective anatomical study aimed to establish an ultrasound-guided technique to the quadratus lumborum (QL) plane in sheep cadavers. Thirteen cadavers, weighing less than 117 kg, were included. In phase 1, one cadaver underwent dissection and two cadavers underwent 3D computed tomographic reconstruction for anatomical evaluation of the thoracolumbar region. In phase 2, two cadavers were used to compare two ultrasound techniques to the QL plane: lateral to the QL muscle with a transversal approach (LQL) and transmuscular between QL and psoas muscles with a longitudinal approach (TQL). For LQL, the reference was the first lumbar transverse process, whereas for TQL, it was the intertransverse region between the first and second lumbar vertebrae. The needle was advanced in-plane towards the specific target for each technique and a total of four injections were performed using 0.4 ml kg-1 of a dye-lidocaine solution. In phase 3, 10 cadavers received bilateral LQL injections (n = 20). All cadavers were then dissected to evaluate spread of dye. In phase 2, following LQL injections, no dye was observed in undesired locations; however, the dye was noted in the retroperitoneal space (1/2) after TQL injections. In phase 3, the 13th thoracic, first, second, third lumbar nerves, and sympathetic trunk segments were stained in 80%, 95%, 100%, 45% and 35% of the injections, respectively. In conclusion, the LQL technique was feasible, allowing staining of the spinal nerves innervating the cranial abdomen in sheep cadavers. Further studies in live animals are warranted.

期刊介绍: The international journal of laboratory animal science and welfare, Laboratory Animals publishes peer-reviewed original papers and reviews on all aspects of the use of animals in biomedical research. The journal promotes improvements in the welfare or well-being of the animals used, it particularly focuses on research that reduces the number of animals used or which replaces animal models with in vitro alternatives.
