Nerve block is useful for the treatment of acute pain and cancer pain; however the treatment's effectiveness with regard to non-cancer chronic pain is controversial. Of the non-cancer diseases, trigeminal neuralgia and spinal facet joint pain, in which long-term pain relief can be obtained by the nerve block without serious complications in most of patients, are well suited for the nerve block. Systemic reviews for the treatment of radicular pain from spine disorders with the nerve block showed contradictory long-term results. In other chronic pains, the effectiveness of nerve blocks has not been proved, although anecdotal reports suggests that a small proportion of patients respond well to the nerve block. Further study is necessary to examine what kinds of pains and patients will be relieved with the nerve block.
神经阻滞对于急性疼痛和癌痛的治疗很有用；然而，其对于非癌性慢性疼痛的治疗效果存在争议。在非癌性疾病中，三叉神经痛和脊柱小关节疼痛通过神经阻滞在大多数患者中可获得长期疼痛缓解且无严重并发症，非常适合进行神经阻滞。关于用神经阻滞治疗脊柱疾病引起的根性疼痛的系统评价显示出相互矛盾的长期结果。在其他慢性疼痛中，神经阻滞的有效性尚未得到证实，尽管有轶事报道表明一小部分患者对神经阻滞反应良好。有必要进一步研究以确定哪些类型的疼痛和患者能通过神经阻滞得到缓解。
