癌症病人在诊断时根据其原发部位不同,大约20%～50%经历过疼痛,晚期癌症病人可高达75%,其中中等的或严重的疼痛占40%～50%,非常严重的或剧痛的占25%～30%,所以癌痛的治疗显得非常重要。我们采用硬膜外腔注射进行癌痛治疗取得了一定的效果〔1〕,但在治疗中亦发生了两例痛觉倒错
The diagnosis of cancer patients varies from about 20% to 50% according to their primary site, and up to 75% of patients with advanced cancers, among which moderate to severe pain accounts for 40% to 50%. Very severe or severe pain This accounts for 25% to 30%, so the treatment of cancer pain is very important. We have achieved certain results with epidural injection for cancer pain treatment [1], but two cases of pain inversion occurred during treatment.
