Perioperative management of the chronic pain patient

The chronic pain patient has certain distinctive features important for her/his perioperative management. Altered opioid sensitivity and behavior are the major points to be considered. The pre-anesthetic visit should therefore include questions regarding chronic pain and regular use of analgesics and coanalgesics, among others. Although a number of characteristics—including increased opioid demand, underreporting of pain, and non-compliance—are known, only a few specific recommendations are available, viz. adequate increase of opioid dose for analgesia, continuation of pre-operative opioids and coanalgesics to prevent withdrawal, and intensive education to strengthen the patientʹs coping potential. No differences between specific techniques for post-operative analgesia (e.g. systemic, patient-controlled or regional analgesia) have been shown so far.
