Objectives

Narrative objectives1

We research prospectively about how many amount of morphine chronic opioid-consuming patients require after surgery.
Many patients suffering from cancer pain or chronic pain use opioids and some of them undergo surgery as same as the other opioid-free patients. In usual, we optimize amount of opioid for postoperative pain considering of patient's data, for example, age, weight, and location and size of wound. Although it is enough for opioid-free patients, we have no idea about how many amount of opioid chronic opioid-consuming patients require so far.
According to the retrospective study we reported (journal of japanese pain clinic society.2012;19(3):436), they required more amount of opioid in 24 hours after surgery than before, regardless of epidural anesthesia and removal of suffering part. However, I have not got enough assessment about complications, for example nausea, somnolence and respiratory depression, in the retrospective study. We research also complications and score of numerical rating scale for estimation of pain relief.
