Realizing that achievement in postoperative pain treatment was not satisfactory, central health authorities in USA, United Kingdom and Australia have published guidelines for managing acute pain. Establishing acute pain services is thought to be one of the means of improving pain relief in the individual patient. Development and research are secured and achieved results may be presented currently. At this moment, introduction of acute pain services is at a preliminary stage in Denmark, and consequently an overview of results obtained from abroad is given including pain treatment techniques, management and safety measures, as well as visions concerning the impact of optimal pain relief upon convalescence. We conclude that the introduction of acute pain services is bound to optimize postoperative patient care and might well prove to be a significant factor in reducing postoperative morbidity.
