The acute pain service

The often inadequate treatment of acute pain is more often due to improper application of available therapies than to the unavailability of effective drugs and techniques. In our institution, the establishment of an acute pain service has improved the safety and efficacy of postoperative pain control. This has been achieved not simply through the immediate availability of a group of specialist physicians and nurses, but also through staff education. The latter has addressed many of the misconceptions preventing proper and safe use of potent analgesic agents. Although provision of intravenously administered patient-controlled analgesia appears not to influence patient outcome, it can result in improved analgesia and patient satisfaction when used properly. Epidurally administered patient-controlled analgesia, on the other hand, appears to provide superior relief of activity pain and earlier resolution of postoperative ileus. The administration of local anesthetic agents, in particular, may reduce reflex diaphragmatic dysfunction following thoracoabdominal surgery and decrease the incidence of graft occlusion following lower extremity vascular procedures. Epidural catheter placement, however, is not without risk, especially in subjects with an established or potential coagulopathy.
