Abstract:The understanding level and attitude of paramedics to cancer pain treatment directly influence the therapeutic result of cancer pain. On the Chinese Cancer Nursing Communion Conference in June 1998, the author made a questionnaire including six aspects about pain control to investigate how much knowledge the nurse's master. (1) General data of responders. (2) The responders' knowledge and the hospital's attitude of "Three stages Acesodyne". (3) The investigation on today's clinical anodyne most in use. (4) The knowledge of assessment methods for cancer pain. (5) The knowledge of being addicted to analgesics. (6) Nursing staff's attitude to curing carcer pain. The result indicates that there are many obstacles in popularizing and carrying out the project of Three Stages Acesodyne. Such as abusing anaesthetic drugs from lack of relative knowledge, misunderstanding for narcotism, lacking of communication among doctors and nurses and evaluating cancer pain insufficieently. The nurse's attitude of pain treatment is also one of the important factors. At the same time , some medical departments of management and hospital leaders do not attach enough importance to cancer pain, which really influences the life qualities of cancer patients, so it is important to renovate the concept.
