BACKGROUND
It has been reported that in 62.5% of cases of incurable cancer pain, the complaint is due to myofascial pain syndrome. Trigger point injections using dibucaine hydrochloride help patients with such cancer pain. This study evaluated the efficacy of trigger point injections for alleviating pain in patients with advanced cancer.
METHODS
Twenty patients with advanced cancer who had a life expectancy of 6 months or less and had been diagnosed with myofascial pain syndrome were treated with trigger point injections. Prior to treatment, a Visual Analog Scale (VAS) was used to measure the resting pain level and discomfort upon application of pressure on the site of pain. These values were compared with last treatment measurements.
RESULTS
The mean pre-treatment VAS scores for pain at rest and upon application of pressure on the pain site were 7.3 and 9.0, respectively. These scores decreased significantly to 1.95 and 3.2, respectively, after the treatment (P<0.05).
CONCLUSION
Trigger point injection is an alternative and effective pain control modality for advanced cancer patients with myofascial pain syndrome.
背景
据报道，在62.5%的无法治愈的癌症疼痛病例中，主诉是由于肌筋膜疼痛综合征。使用盐酸丁卡因进行触发点注射有助于缓解此类癌症疼痛患者的症状。本研究评估了触发点注射对缓解晚期癌症患者疼痛的疗效。
方法
对20例预期寿命6个月或更短且已被诊断为肌筋膜疼痛综合征的晚期癌症患者进行触发点注射治疗。治疗前，使用视觉模拟量表（VAS）测量静息时的疼痛水平以及在疼痛部位施加压力时的不适程度。将这些值与最后一次治疗测量值进行比较。
结果
静息时疼痛和在疼痛部位施加压力时的治疗前VAS平均评分分别为7.3和9.0。治疗后，这些评分显著降至1.95和3.2（P<0.05）。
结论
触发点注射是晚期癌症合并肌筋膜疼痛综合征患者的一种替代且有效的疼痛控制方式。
