In the RDS infants, the gastric aspirate L\/S value was immature in 94.1 %. The gastric aspirate L\/S values of the infants with transient tachypnea or perinatal asphyxia did not differ significantly from those of the healthy infants. The severity of RDS correlated inversely to the gastric aspirate L\/S value (r = \u2013\u20130.63, p &lt; 0.001, n = 17). The gastric aspirate L\/S value can be used in differential diagnosis between RDS and other neonatal breathing difficulites. It is also a predictor of the severity of the developing RDS.<\/jats:p>","DOI":"10.1159\/000299409","type":"journal-article","created":{"date-parts":[[2010,3,17]],"date-time":"2010-03-17T05:58:36Z","timestamp":1268805516000},"page":"177-184","source":"Crossref","is-referenced-by-count":4,"title":["Gastric Aspirate Lecithin\/Sphingomyelin Ratio and Neonatal Breathing Difficulties"],"prefix":"10.1159","author":[{"given":"H.","family":"Korvenranta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,16]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000299409","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:39:15Z","timestamp":1777617555000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000299409"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000299409","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,16]]}}}
