Acute pain is a symptom that originates from actual ongoing or impending tissue damage. Pain is an individual subjective experience and varies markedly among individuals. For this reason, patient involvement is essential, with the most reliable indicator of severity being patient self-report. The main objective of postoperative pain management is the achievement of fast rehabilitation, recovery of all normal functions and reduction of postoperative morbidity. Sufficient evidence supports the hypothesis that effective analgesia modifies many of the adverse sequelae that accompany acute pain and assists in recovery. Nevertheless, despite the availability of drugs and techniques for its effective management, postoperative pain remains undertreated. It is now accepted that the solution to the problem of inadequate pain relief lies not only in the development of new analgesic drugs or technologies but also in the development of an appropriate organization to utilize existing expertise. Methods used to control postoperative pain are numerous; this review focuses on pharmacological and anesthetic methods.
