It occurs mainly in the second stage of labor and is potentially lethal. We report the case of a 29-year-old primiparous woman during the immediate puerperium (Leff\u2019s fourth stage of labor) presenting with acute chest pain, dyspnea and petechiae. She was admitted to the intensive care unit with a suspected diagnosis of amniotic fluid embolism. A chest radiograph revealed a pneumomediastinum that finally resolved with oxygen therapy and supportive management in 3 days.<\/jats:p>","DOI":"10.1159\/000162103","type":"journal-article","created":{"date-parts":[[2008,10,20]],"date-time":"2008-10-20T07:39:40Z","timestamp":1224488380000},"page":"70-72","source":"Crossref","is-referenced-by-count":10,"title":["Pneumomediastinum during the Fourth Stage of Labor"],"prefix":"10.1159","volume":"67","author":[{"given":"Ignacio","family":"Zapardiel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesus","family":"Delafuente-Valero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginia","family":"Diaz-Miguel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Godoy-Tundidor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose Manuel","family":"Bajo-Arenas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2008,10,9]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ijoa.2003.12.001"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/162103","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/162103","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T01:02:42Z","timestamp":1745456562000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000162103"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,10,9]]},"references-count":1,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2009,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000162103","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,10,9]]}}}
