These clinical indicators are associated with increased mortality in preterm human newborns with respiratory distress syndrome (RDS). The aim of this study was to investigate the prognostic importance of venous pH, partial pressure of carbon dioxide (pCO\n                    <jats:sub>2<\/jats:sub>\n                    ) and lactate level and which parameters are related with mortality in premature calves with RDS. All premature calves (52 male\/58 female) were admitted to clinic within 12\u201324 hours after birth and blood samples were also taken into heparinised plastic syringes from the jugular vein within 30 minutes following admission. Diagnosis of RDS was made by both clinical signs and blood gas results. For the evaluation of independent samples, t test was used to compare the venous blood gas indicators of surviving and non\u2010surviving premature calves. Receiver operating characteristics curves were used to determine a cut\u2010off value in terms of lactate and pCO\n                    <jats:sub>2<\/jats:sub>\n                    measurements among non\u2010surviving and surviving calves. Venous pH, pCO\n                    <jats:sub>2<\/jats:sub>\n                    , SatO\n                    <jats:sub>2<\/jats:sub>\n                    , base deficit, bicarbonate (HCO\n                    <jats:sub>3<\/jats:sub>\n                    ) and lactate levels showed a significant variance between surviving and non\u2010surviving calves. Mean venous pH, pCO\n                    <jats:sub>2<\/jats:sub>\n                    , SatO\n                    <jats:sub>2<\/jats:sub>\n                    , lactate levels in non\u2010surviving premature calves was 7.05, 78.9\u00a0mm Hg, 16.1 per cent and 9.50\u00a0mmol\/l, respectively. Mean pH, pCO\n                    <jats:sub>2<\/jats:sub>\n                    , SatO\n                    <jats:sub>2<\/jats:sub>\n                    and lactate levels in surviving premature calves were 7.29, 56.3\u00a0mm Hg, 25.5 per cent and 5.1\u00a0mmol\/l, respectively. The cut\u2010off values for lactate and pCO\n                    <jats:sub>2<\/jats:sub>\n                    were 7.5\u00a0mmol\/l and 63.5\u00a0mm Hg, respectively. In conclusion, the results of the study show that venous blood lactate and pCO\n                    <jats:sub>2<\/jats:sub>\n                    have prognostic importance in premature calves with RDS.\n                  <\/jats:p>","DOI":"10.1136\/vr.103730","type":"journal-article","created":{"date-parts":[[2017,3,27]],"date-time":"2017-03-27T20:56:41Z","timestamp":1490648201000},"page":"611-611","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["Venous lactate, pH and partial pressure of carbon dioxide levels as prognostic indicators in 110 premature calves with respiratory distress syndrome"],"prefix":"10.1002","volume":"180","author":[{"given":"R.","family":"Yildiz","sequence":"first","affiliation":[{"name":"Department of Internal Medicine Mehmet Akif Ersoy University Burdur Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U.","family":"Aydogdu","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Cumhuriyet University Sivas Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Guzelbektes","sequence":"additional","affiliation":[{"name":"Kyrgyzstan Manas University Bishkek Kyrgyzstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Coskun","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Cumhuriyet University Sivas Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Sen","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Selcuk University Konya Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,6,24]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1556\/004.2016.004"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.47.254.550"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cvfa.2008.10.002"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.101192"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.161.20.688"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.233.2.289"},{"key":"e_1_2_5_8_1","unstructured":"2010 W.
