A discussion of a patient\u2019s perioperative opioid management and mechanisms contributing to opioid-induced hyperalgesia (OIH) are presented. In the present case report, a patient on high doses of opioids, including morphine and methadone, with severe worsening back pain and a history of increasing opioid requirements for the last 2 months due to metastatic leiomyosarcoma to the femur, spine, and neck is described. Use of high dose opioids is associated with numerous challenges, including tolerance. The successful management of this patient was multimodal and included the use of potent analgesics, N-methyl-D-aspartatereceptor antagonists, and the \u03b1-2 agonist clonidine.<\/jats:p>","DOI":"10.5055\/jom.2014.0194","type":"journal-article","created":{"date-parts":[[2014,3,31]],"date-time":"2014-03-31T15:47:26Z","timestamp":1396280846000},"page":"69-72","source":"Crossref","is-referenced-by-count":6,"title":["Perioperative dilemma: Challenges of the management of a patient on mega doses of morphine and methadone"],"prefix":"10.5055","volume":"10","author":[{"given":"Alan David","family":"Kaye, MD, PhD, DABA, DABPM, DABIPP","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aymen A.","family":"Alian, MD","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nalini","family":"Vadivelu, MD","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keun Sam","family":"Chung, MD","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3008","published-online":{"date-parts":[[2014,1,1]]},"container-title":["Journal of Opioid Management"],"original-title":[],"link":[{"URL":"https:\/\/wmpllc.org\/ojs\/index.php\/jom\/article\/download\/639\/614","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/wmpllc.org\/ojs\/index.php\/jom\/article\/download\/639\/614","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,1]],"date-time":"2023-05-01T19:49:46Z","timestamp":1682970586000},"score":1,"resource":{"primary":{"URL":"https:\/\/wmpllc.org\/ojs\/index.php\/jom\/article\/view\/639"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2014,1,1]]}},"URL":"https:\/\/doi.org\/10.5055\/jom.2014.0194","relation":{},"ISSN":["1551-7489","1551-7489"],"issn-type":[{"value":"1551-7489","type":"electronic"},{"value":"1551-7489","type":"print"}],"subject":[],"published":{"date-parts":[[2014,1,1]]}}}
