To evaluate the efficacy of scalene injection in patients with thoracic outlet syndrome.
We selected 142 patients diagnosed with thoracic outlet syndrome between January 2005 and October 2009. We performed a series of scalene injection with conservative treatment in all cases. Patients rated their pain degrees using a visual analogue scale. We also evaluated the time to return to everyday life and work, and patients' functional capacity.
There were no complications or instances of inadvertent somatic or sympathetic ganglionic blockade after scalene injection. Overall, 111 patients (76.5%) experienced improved symptoms after the first set of scalene injection and 128 patients (88.2%) improved after scalene injection followed by conservative treatment. Of the 68 patients who returned to work during the study period, 54 returned within 1 week, and 62 within 2 weeks. Of those who returned to work, 61 reported nearly full functional capacity. We found that scalene injection was more effective in cases of thoracic outlet syndrome related to trauma than in those related to work-related repetitive stress.
In patients with thoracic outlet syndrome, scalene injection effectively reduces pain. We recommend scalene injection as an adjunct to conservative treatment.
评估斜角肌注射治疗胸廓出口综合征患者的疗效。
选取2005年1月至2009年10月间诊断为胸廓出口综合征的142例患者。所有病例均采用一系列斜角肌注射并结合保守治疗。患者使用视觉模拟量表对疼痛程度进行评分。我们还评估了恢复日常生活和工作的时间以及患者的功能能力。
斜角肌注射后未出现并发症，也未发生意外的躯体或交感神经节阻滞情况。总体而言，111例患者（76.5%）在首次斜角肌注射后症状改善，128例患者（88.2%）在斜角肌注射后结合保守治疗症状改善。在研究期间恢复工作的68例患者中，54例在1周内恢复，62例在2周内恢复。在恢复工作的患者中，61例报告功能能力几乎完全恢复。我们发现，斜角肌注射对创伤性胸廓出口综合征的疗效比对与工作相关的重复性压力相关的胸廓出口综合征更有效。
对于胸廓出口综合征患者，斜角肌注射可有效减轻疼痛。我们建议将斜角肌注射作为保守治疗的辅助手段。
