Thus, our objective was to describe these findings.<\/jats:p><jats:p>\n          Study Design\u2003This was a retrospective study of laboring term gestations with no history of hypertensive disorders. Intrapartum blood pressures were reviewed, and women were subdivided based on blood pressures: normal (&lt;140\u2009mm Hg systolic and &lt;90\u2009mm Hg diastolic), mild hypertension (140\u2013159 or 90\u2013109), and severe hypertension (\u2265 160 or\u2009\u2265\u2009110). Groups were compared using chi-square test and analysis of variance.<\/jats:p><jats:p>\n          Results\u2003A total of 724 women were studied during 4 months: 248 (34%) had mild and 69 (10%) had severe hypertension. Severe hypertensives were more likely to be nulliparous, obese, or have received an epidural or oxytocin. There were no cases of eclampsia, stroke, or pulmonary edema in severe hypertensives (95% confidence interval, 0\u20135). Despite severely elevated pressures, only 4\/69 (6%) patients received intravenous antihypertensive therapy, and 3 (4%) required medications at discharge.<\/jats:p><jats:p>\n          Conclusion\u2003One in 3 women exhibits mild hypertension and 1 in 10 develop severe hypertension in labor. Only 6% of patients received treatment for severe blood pressures. This study highlights lack of treatment of hypertension in labor and further investigation into causes and outcomes of intrapartum elevations of blood pressures.<\/jats:p>","DOI":"10.1055\/s-0039-1683875","type":"journal-article","created":{"date-parts":[[2019,3,21]],"date-time":"2019-03-21T02:45:51Z","timestamp":1553136351000},"page":"543-547","source":"Crossref","is-referenced-by-count":4,"title":["Prevalence and Risk Factors for New-Onset Hypertension in Labor"],"prefix":"10.1055","volume":"37","author":[{"given":"Nana-Ama E.","family":"Ankumah","sequence":"additional","affiliation":[{"name":"Division of Maternal-Fetal Medicine, Department of Obstetrics, Gynecology and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mesk A.","family":"Alrais","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farah H.","family":"Amro","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel L.","family":"Wiley","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baha M.","family":"Sibai","sequence":"additional","affiliation":[{"name":"Division of Maternal-Fetal Medicine, Department of Obstetrics, Gynecology and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,3,20]]},"container-title":["American Journal of Perinatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-1683875.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,30]],"date-time":"2020-03-30T22:40:47Z","timestamp":1585608047000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-1683875"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,3,20]]},"references-count":0,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2020,3,30]]},"published-print":{"date-parts":[[2020,4]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-1683875","relation":{},"ISSN":["0735-1631","1098-8785"],"issn-type":[{"value":"0735-1631","type":"print"},{"value":"1098-8785","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,3,20]]}}}
