Continuous brachial plexus anesthesia with local anesthesia has been used since 1946 for prolonged surgical procedures, in postoperative pain relief, and in sympathetic nerve block. The benefit or effectiveness of this technique in the relief of sympathetically maintained pain has yet to be established.
The following case report describes the placement of an axillary catheter connected to a port for the self-administration of local anesthesia to provide brachial plexus anesthesia in a 43-year-old woman suffering from sympathetically maintained pain.
The administration of local anesthesia through this injection system resulted in complete pain relief without motor impairment of the arm. The device functioned for 118 days, making physical therapy easier. An infection occurred at the entry site, requiring the removal of the port.
Controlled studies need to be done to establish the safety and efficacy of this form of therapy.
自1946年以来，局部麻醉下的连续臂丛神经麻醉已用于长时间外科手术、术后疼痛缓解及交感神经阻滞。该技术在缓解交感神经维持性疼痛方面的益处或有效性尚未确立。
以下病例报告描述了在一名患有交感神经维持性疼痛的43岁女性中，放置与端口相连的腋部导管用于局部麻醉自我给药以提供臂丛神经麻醉的情况。
通过该注射系统给予局部麻醉导致疼痛完全缓解，且手臂无运动功能障碍。该装置运行了118天，使物理治疗更容易。入口部位发生感染，需要移除端口。
需要进行对照研究以确立这种治疗方式的安全性和有效性。
