Hyponatraemia is a rare complication of pre-eclampsia. A 41-year-old, para 0+1 in vitro fertilisation monochorionic diamniotic triplet pregnancy woman presented at 25\u2005weeks with dyspnoea and general malaise. Her antenatal course was complicated by the diagnosis of intrauterine growth restriction in triplet one at 27\u2005weeks of gestation. At 27+3\u2005weeks gestation, she was diagnosed as having pre-eclampsia. Subsequent biochemical analysis demonstrated hyponatraemia with serum sodium falling steadily to 117\u2005mmol\/L over the next 19\u2005days. She was admitted to intensive care unit for stabilisation of fulminant pre-eclampsia and severe hyponatraemia at 30+5\u2005weeks of gestation. Hypertonic saline and intravenous labetolol were administered prior to delivery by caesarean section. She recovered well postdelivery with stabilisation of her blood pressure and normalisation of her sodium level to 135\u2005mmol\/L. Awareness and frequent monitoring of hyponatraemia should become an integral part of monitoring women with pre-eclampsia.<\/jats:p>","DOI":"10.1136\/bcr-2016-215036","type":"journal-article","created":{"date-parts":[[2016,8,24]],"date-time":"2016-08-24T10:23:14Z","timestamp":1472034194000},"page":"bcr2016215036","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["Severe hyponatraemia associated with pre-eclampsia"],"prefix":"10.1136","volume":"2016","author":[{"given":"Breffini","family":"Anglim","sequence":"first","affiliation":[{"name":"Limerick Maternity Hospital, Limerick, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirk","family":"Levins","sequence":"additional","affiliation":[{"name":"Limerick Maternity Hospital, Limerick, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neidin","family":"Bussmann","sequence":"additional","affiliation":[{"name":"CUMH, Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mendinaro","family":"Imcha","sequence":"additional","affiliation":[{"name":"Limerick Maternity Hospital, Limerick, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2016,8,24]]},"reference":[{"key":"2025082623322242000_2016.aug24_1.bcr2016215036.1","unstructured":"Villar J , Say L , Gulmezoglu AM , et al .
