血液透析患者的动静脉内瘘或动静脉移植物发生功能障碍时，常需要通过经皮腔内血管成形术恢复血管通路功能。这类操作虽然属于血管介入治疗，但球囊扩张和病变处理过程中可能产生明显疼痛，影响患者配合和操作体验。超声引导腋路臂丛神经阻滞能够覆盖上肢感觉传入，理论上可为这类操作提供更有针对性的镇痛。那么，功能障碍性血管通路介入治疗中，超声引导腋路臂丛神经阻滞真的可以减轻疼痛吗？
下面这篇文献将回答这个问题。
文献英文标题
Ultrasound-guided axillary brachial plexus block provides analgesia during percutaneous transluminal angioplasty for arteriovenous fistula or arteriovenous graft failures.
英文摘要要点
Methods:
We retrospectively reviewed patient data, including the decision to perform an ultrasound-guided axillary brachial plexus block and severity of pain during PTA, assessed using the Numerical Rating Scale (NRS).
Results:
Of 342 patients, axillary brachial plexus block was performed in 156 patients. The NRS scores (mean ± standard deviation) were lower in patients who received the block compared to those who did not, regardless of the VA type, anastomosis site (radial, ulnar, or near the elbow), or dilation site (distal or proximal to the anastomotic outflow).
Conclusions:
Ultrasound-guided axillary brachial plexus block effectively reduced pain during PTA for dysfunctional VA, independent of access type or lesion site.

超声引导腋路臂丛神经阻滞可在动静脉内瘘或动静脉移植物失功经皮腔内血管成形术中提供镇痛
文献简介
功能障碍性血管通路接受经皮腔内血管成形术时，球囊扩张和病变处理可能造成明显疼痛。对于动静脉内瘘或动静脉移植物失功患者，如何在保证介入治疗顺利完成的同时改善操作中镇痛，是血管通路维护中值得关注的问题。这项研究围绕超声引导腋路臂丛神经阻滞，评估其在功能障碍性血管通路经皮腔内血管成形术中的镇痛效果。
