<qa>  What is the mainstay of acute postoperative pain management?Postoperative pain is often undertreated. Although studies have demonstrated that many patients experience a substantial degree of unrelieved pain following operative procedures and that this pain can increase the incidence of serious complications, the management of discomfort continues to be suboptimal. Narcotic analgesia is the mainstay of acute postoperative pain management but patient, clinician, and institutional barriers often limit the effectiveness of drug treatment. Furthermore, pharmacologic interventions alone may not address all the factors involved in the conscious experience of pain. Massage is a complementary or adjunctive medical technique that has been used for thousands of years. Yet there is scant research related to the use of massage therapy in postoperative pain management. Used in tandem with pharmacologic treatments, massage may have the potential to substantially improve acute pain relief.
