Six of the mothers received ritodrine by infusion and the other 6 physiological saline during the 2 h prepartum. The Apgar scores of the treatment group were higher (p &lt; 0.05) but there was a significant increase in RR (p &lt; 0.05) during the first hour in these babies. Arterial blood pressure (BP) was lower in the group whose mothers had received ritodrine (p &lt; 0.05) but there was no difference in pulse pressure. Transcutaneous pressure of CO&lt;sub&gt;2&lt;\/sub&gt; (P&lt;sub&gt;tc&lt;\/sub&gt;CO&lt;sub&gt;2&lt;\/sub&gt;) of the controls decreased during the first hour (p &lt; 0.05). Transcutaneous pressure of O&lt;sub&gt;2&lt;\/sub&gt; (P&lt;sub&gt;tc&lt;\/sub&gt;O&lt;sub&gt;2&lt;\/sub&gt;) increased during the first postnatal hour (p &lt; 0.01) when both groups were examined together. HR of both groups was relatively high and HRV low.<\/jats:p>","DOI":"10.1159\/000298856","type":"journal-article","created":{"date-parts":[[2010,3,16]],"date-time":"2010-03-16T04:07:18Z","timestamp":1268712438000},"page":"160-166","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Antepartum Ritodrine on the Cardiorespiratory Status of the Newborn after Elective Cesarean Section"],"prefix":"10.1159","author":[{"given":"Tuula","family":"Aarimaa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulla","family":"Ekblad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Risto","family":"Erkkola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jussi","family":"Kanto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pentti","family":"Kero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,15]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000298856","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:34:15Z","timestamp":1777617255000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000298856"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,15]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000298856","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,15]]}}}
