摘要
目的:开发一种超声(US)引导的臂丛(BP)腹侧入路,并评估枭鸮尸体的神经解剖和染色:开发一种超声(US)引导的臂丛(BP)腹侧入路,并评估枭鸮尸体的神经解剖和染色情况:研究设计:前瞻性尸体研究:11具成年雄性和雌性枭鸮尸体,体重为0.43-0.98千克:方法:将 11 具冷冻尸体解冻 48 小时,称重并进行身体状况评分。将 10 具尸体置于背卧位,双翼内收。将 13-6 MHz 线性探针置于肩肱关节腹侧,与胸骨平行,在 US 引导下观察 BP。将 22 号 50 毫米绝缘针头从尾部向颅内方向推进。为每只猫头鹰注射 0.4 mL kg-1 的 1:1 0.5% 罗哌卡因和 1%亚甲蓝溶液,针对一个 BP。注射后 15 分钟进行解剖。如果周缘染色≥ 1 厘米,则认为神经染色成功。在第 11 具猫头鹰尸体的两侧翅膀注射 1:1 的 1%亚甲蓝和 74%碘伏对比剂溶液,注射前和注射后 15 分钟进行计算机断层扫描(CT):结果:在体重大于 0.5 千克的尸体上,超声波可清晰地识别出 BP。注射剂量为 0.4 mL kg-1 时,所有尸体的 BP 分支都能完全染色。结论和临床意义:在 US 引导下,采用腹腔方法对体重大于 0.5 千克的枭鸮尸体进行 BP 注射非常容易。注射 0.4 mL kg-1 的罗哌卡因染料溶液可使所有翅膀的 BP 分支完全染色,这表明该技术可为肩胛肱关节远端结构提供镇痛。有必要进行临床研究,以确认该技术在枭类猫头鹰和其他鸟类中的安全性和有效性。
Ultrasound-guided ventral approach to the brachial plexus block in barred owls (Strix varia): a cadaveric study.
Objective: To develop an ultrasound (US)-guided ventral approach to the brachial plexus (BP) and evaluate nerve anatomy and staining in barred owl cadavers.
Study design: Prospective, cadaveric study.
Animals: Eleven adult male and female barred owl cadavers with a body mass of 0.43-0.98 kg.
Methods: Eleven frozen cadavers were thawed for 48 hours, weighed and assigned a body condition score. Ten cadavers were placed in dorsal recumbency with wings abducted. US-guided visualization of the BP was achieved by placing a 13-6 MHz linear probe over the ventral aspect of the scapulohumeral joint, parallel to the sternum. A 22 gauge, 50 mm insulated needle was advanced in-plane in a caudal-to-cranial direction. In each owl, injection targeting one BP was performed with 0.4 mL kg-1 of a 1:1 0.5% ropivacaine and 1% methylene blue solution. Dissection was performed 15 minutes postinjection. Nerve staining was deemed successful if ≥ 1 cm of circumferential staining was achieved. The eleventh owl cadaver was injected with a 1:1 solution of 1% methylene blue and 74% ioversol contrast into both wings, and computed tomography (CT) was performed just before and 15 minutes after injection.
Results: The BP was clearly identified ultrasonographically in cadavers weighing > 0.5 kg. An injectate volume of 0.4 mL kg-1 provided complete staining of the BP branches in all cadavers. CT scan revealed no contrast within the coelomic cavity.
Conclusions and clinical relevance: The US-guided BP injection using a ventral approach was easily performed in barred owl cadavers weighing > 0.5 kg. The injection of 0.4 mL kg-1 of a ropivacaine-dye solution resulted in complete staining of the BP branches in all wings, suggesting that this technique could provide analgesia for structures distal to the scapulohumeral joint. Clinical studies are necessary to confirm the safety and efficacy of this technique in barred owls and other bird species.
期刊介绍:
Veterinary Anaesthesia and Analgesia is the official journal of the Association of Veterinary Anaesthetists, the American College of Veterinary Anesthesia and Analgesia and the European College of Veterinary Anaesthesia and Analgesia. Its purpose is the publication of original, peer reviewed articles covering all branches of anaesthesia and the relief of pain in animals. Articles concerned with the following subjects related to anaesthesia and analgesia are also welcome:
the basic sciences;
pathophysiology of disease as it relates to anaesthetic management
equipment
intensive care
chemical restraint of animals including laboratory animals, wildlife and exotic animals
welfare issues associated with pain and distress
education in veterinary anaesthesia and analgesia.
Review articles, special articles, and historical notes will also be published, along with editorials, case reports in the form of letters to the editor, and book reviews. There is also an active correspondence section.
