Intravenous magnesium was initiated and a lumbar epidural catheter was placed uneventfully for labor analgesia. The patient reported complete relief of her CRPS-associated pain during and for 24 hours after delivery, while receiving intravenous magnesium, with her pain symptoms returning shortly after discontinuing magnesium. To our knowledge, there are no case reports that describe CRPS-associated pain relief while on peripartum magnesium therapy.<\/jats:p>","DOI":"10.1136\/rapm-2018-100142","type":"journal-article","created":{"date-parts":[[2019,1,12]],"date-time":"2019-01-12T02:45:30Z","timestamp":1547261130000},"page":"521-523","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Complete relief of CRPS-associated pain during magnesium infusion in a patient with postpartum preeclampsia"],"prefix":"10.1136","volume":"44","author":[{"given":"Jonathan A","family":"Niconchuk","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Vanderbilt University Medical Center, Nashville, Tennessee, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3236-9059","authenticated-orcid":false,"given":"Michael G","family":"Richardson","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Vanderbilt University Medical Center, Nashville, Tennessee, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,1,11]]},"reference":[{"key":"2025101113115442000_44.4.521.1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1016\/j.ejps.2016.11.020","article-title":"Magnesium enhances opioid-induced analgesia - What we have learnt in the past decades?","volume":"99","author":"Bujalska-Zadro\u017cny","year":"2017","journal-title":"Eur J Pharm Sci"},{"key":"2025101113115442000_44.4.521.2","doi-asserted-by":"publisher","DOI":"10.1097\/ALN.0b013e318297630d"},{"key":"2025101113115442000_44.4.521.3","doi-asserted-by":"publisher","DOI":"10.7453\/gahmj.2013.008"},{"key":"2025101113115442000_44.4.521.4","doi-asserted-by":"crossref","first-page":"424","DOI":"10.2174\/0929867323666161213101744","article-title":"Magnesium in pain research: state of the art","volume":"24","author":"Srebro","year":"2017","journal-title":"Curr Med Chem"},{"key":"2025101113115442000_44.4.521.5","doi-asserted-by":"crossref","first-page":"1388","DOI":"10.1111\/pme.12211","article-title":"Intravenous magnesium for chronic complex regional pain syndrome type 1 (CRPS-1)","volume":"14","author":"Fischer","year":"2013","journal-title":"Pain Med"},{"key":"2025101113115442000_44.4.521.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.2012.07335.x"},{"key":"2025101113115442000_44.4.521.7","doi-asserted-by":"crossref","first-page":"1341","DOI":"10.1016\/j.jpain.2013.05.013","article-title":"An explanatory study evaluating the muscle relaxant effects of intramuscular magnesium sulphate for dystonia in complex regional pain syndrome","volume":"14","author":"van der Plas","year":"2013","journal-title":"J Pain"},{"key":"2025101113115442000_44.4.521.8","doi-asserted-by":"publisher","DOI":"10.1097\/00000539-199510000-00029"},{"key":"2025101113115442000_44.4.521.9","doi-asserted-by":"crossref","first-page":"517","DOI":"10.1007\/s00228-005-0967-9","article-title":"Pharmacokinetics and transplacental distribution of fentanyl in epidural anesthesia for normal pregnant women","volume":"61","author":"Mois\u00e9s","year":"2005","journal-title":"Eur J Clin Pharmacol"}],"container-title":["Regional Anesthesia &amp; Pain Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/rapm-2018-100142","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,11]],"date-time":"2025-10-11T20:12:02Z","timestamp":1760213522000},"score":1,"resource":{"primary":{"URL":"https:\/\/rapm.bmj.com\/lookup\/doi\/10.1136\/rapm-2018-100142"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1,11]]},"references-count":9,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,3,26]]},"published-print":{"date-parts":[[2019,4]]}},"alternative-id":["10.1136\/rapm-2018-100142"],"URL":"https:\/\/doi.org\/10.1136\/rapm-2018-100142","relation":{},"ISSN":["1098-7339","1532-8651"],"issn-type":[{"type":"print","value":"1098-7339"},{"type":"electronic","value":"1532-8651"}],"subject":[],"published":{"date-parts":[[2019,1,11]]}}}
