Effect of post-operative analgesia on patient morbidity.

The pathophysiology that commonly follows surgery results in detrimental physiological effects and may be associated with post-operative mortality and morbidity. The use of post-operative epidural analgesia, but not systemic opioids, may attenuate some of these adverse physiological effects and result in a decrease in patient-related morbidity post-operatively. Randomized trials suggest that the perioperative use of epidural analgesia may facilitate return of gastrointestinal function, attenuate hypercoagulable events and diminish post-operative pulmonary complications. A multimodal approach incorporating the use of epidural analgesia to control perioperative pathophysiology will facilitate the patient's recovery.
