Animals (n = 72) ventilated with pure oxygen were given human meconium suspension (50\u201375 mg kg<sup>\u20131<\/sup>) through the airways. When the PaO<sub>2<\/sub> had decreased to <20 kPa (mean \u00b1 SD 12 \u00b1 3.9 kPa), the rats were randomly allocated to ten groups (G). G 6\u201310 underwent lung lavage with diluted Curosurf (5 mg ml<sup>\u20131<\/sup>, 20 ml kg<sup>\u20131<\/sup>), whereas G 1\u20135 did not. G 1 and 6 received no additional material through the airways. G 2 and 7 received Curosurf (100 mg kg<sup>\u20131<\/sup>), and G 3 and 8 received Curosurf (100\u00a0mg kg<sup>\u20131<\/sup>) plus dextran (75 mg kg<sup>\u20131<\/sup>); G 4 and 9 received Curosurf (200 mg kg<sup>\u20131<\/sup>), and G 5 and G 10 received Curosurf (200 mg kg<sup>\u20131<\/sup>) plus dextran (75 mg kg<sup>\u20131<\/sup>). All rats in G\u00a01 died before 180 min after randomization. In G 2, 3, 6, 7, and 8, the PaO<sub>2<\/sub> transiently increased to 30\u201340 kPa. In G 4, 5, 9, and 10, the PaO<sub>2<\/sub> remained >30\u00a0kPa for 180 min. Both airway lavage and supplementation with dextran improved the therapeutic effects of surfactant; however, a large dose (200 mg kg<sup>\u20131<\/sup>) was nevertheless required to optimize gas exchange.<\/jats:p>","DOI":"10.1159\/000067009","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T21:05:40Z","timestamp":1050440740000},"page":"49-56","source":"Crossref","is-referenced-by-count":16,"title":["Modified Protocols for Surfactant Therapy in Experimental Meconium Aspiration Syndrome"],"prefix":"10.1159","volume":"83","author":[{"given":"Katsumi","family":"Tashiro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-Guang","family":"Cui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsutomu","family":"Kobayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tore","family":"Curstedt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bengt","family":"Robertson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2003,1,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1099-0496(199907)28:1<18::AID-PPUL4>3.0.CO;2-O"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/67009","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/67009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:20:47Z","timestamp":1745464847000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000067009"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003]]},"references-count":1,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2003,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000067009","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003]]}}}
