One topical mechanism is opioid induced influence of N-methyl-d-aspartate (NMDA)-receptor and its intracellular second-messenger-systems. This results in central sensitization to pain stimulus in the dorsal horn and the brain (4-5), with following development of hyperalgesia.\n\nSeveral strategies can be successful to reduce or prevent opioid induced hyperalgesia, for example NMDA-receptor antagonists, alfa-2 agonists, opioid rotation or combination of opioids with different receptor selectivity (6-8).\n\nThe theoretical background for pre-treating the opioid receptor with an other opioid (fentanyl) that gives less tendency to hyperalgesia than remifentanil, is that it can reduce the development of tolerance and hyperalgesia of remifentanil.\n\nThe aim of this trial is to examine the possibility that i.v. administration of fentanyl 1,5 µgr/kg before start of remifentanil infusion for anesthesia gives less development of tolerance/hyperalgesia postoperative than fentanyl given in the end of surgery (the traditional method).\n\nThis is to be measured by less pain postoperative (VAS, visual analog scale, and a five point verbal rating scale) and less fentanyl consumed (measured by using PCA).\n\nLiterature:\n\n1.
