IMPLICATIONS: The combination of preoperative epidural clonidine with postoperative patient-controlled analgesia morphine, ropivacaine, and clonidine provides preemptive analgesia and results in reduced pain intensity, diminished opioid consumption, a faster return of bowel function, and attenuated production of interleukin (IL)-6, IL-8, and IL-1 receptor antagonist (RA) in the perioperative period, without any complications. The lower levels of IL-6, IL-8, and IL-1RA could diminish pain transmission and central nervous system sensitization, thus improving postoperative pain and allowing a faster return of bowel function.
