Patient experience of pain after elective noncardiac surgery

The purpose of this study was to examine the extent and evolution of pain after common major surgical procedures and to establish correlates of three types of pain: pain at rest, pain with movement, and maximum pain over the previous 24 h. Patients completed a preoperative questionnaire to obtain data on age, gender, narcotic use, baseline level of pain, chronicity of pain, and level of anxiety. Patients were then interviewed on Postoperative Days 1, 2, and 3 to assess their pain on a scale of 0 (none) to 10 (worst imaginable). The mean pain score at rest was 2.6 on Postoperative Day 1 and decreased to 2.3 on Postoperative Day 3 (P = 0.06). The mean pain score with movement was 4.5 on Postoperative Day 1, which decreased to 4.2 on Postoperative Day 3 (P = 0.03). The mean maximum pain score over the previous 24 h was 6.3, which decreased to 5.6 (P = 0.0001). Preoperative narcotic use and high baseline preoperative pain, defined as a score greater than or equal to 4, were significantly (P < 0.05) associated with increased pain at rest, pain with movement, and maximum pain. Epidural analgesia was the only mode of analgesia significantly associated with both decreased postoperative pain at rest and decreased pain with movement (P < 0.05). These relatively high pain scores and minimum decreases in pain from Postoperative Days 1 to 3 emphasizes the need for more effective pain management continuing into the postoperative period to facilitate mobilization and recovery.
