慢性手术后疼痛及现代治疗

Chronic Post-surgical Pain and Clinical Treatment

由于慢性手术后疼痛产生的原因比较复杂．临床上大多数患者对于常规的口服药物或治疗方法效果差，使得许多外科医生感到非常棘手。慢性手术后疼痛并非在手术后跟随急性疼痛后连续发生，常常在数周或数月后出现。例如在美国每年仅脊柱外科手术超过30万例，其中10～40％的在手术后发生数周以疼痛为主要症状的临床综合征；目前在国内还缺乏系统的流行病学资料和统计。因此慢性手术后疼痛还没有被大多数医师认识，本文通过资料综合，较为系统的介绍慢性手术后疼痛的可能机制、临床表现和伴随症状．现代治疗新概念。
