癌症疼痛严重影响着癌症患者的生活质量和治疗效果,据估计,全球每年约有700万新发生的癌症病例,其中30—50％伴有程度不同的疼痛,且大多数均未达到有效止痛,此现象在我国尤为严重,广大医务人员担心使用吗啡等强止痛剂会使病人成瘾,但国外资料表明,癌症患者长期使用麻醉性镇痛剂很少成瘾。 Cancer pain seriously affects the quality of life and therapeutic effect of cancer patients. It is estimated that there are approximately 7 million new cases of cancer each year in the world, 30 to 50% of which have different degrees of pain, and most of them have not reached effective pain relief. This phenomenon is particularly serious in our country. The majority of medical staff are worried that the use of strong analgesics such as morphine will make patients addicted, but foreign data show that long-term use of narcotic analgesics cancer patients rarely addiction.
