Persistent postsurgical and posttrauma pain.

摘要

IT IS ESTIMATED that as many as 50% of patients who have undergone surgery experience persistent pain long after the expected postoperative recovery period, and in 2% to 10% of these individuals, the intensity of the pain is severe (see Table 1 for incidence associated with various surgical procedures). This type of pain is common in chronic pain centers, where as many as 20% of individuals seeking help report surgery as the origin of their pain.
