We utilized an anesthetic conserving device (Sedaconda-ACD) to administer total inhaled anesthesia because specific vaporizers were unavailable for administering inhaled agents during cardiopulmonary bypass (CPB) in our center. We documented our experience and postoperative cardiovascular outcomes. The primary outcome was the peak level of troponin, with secondary outcomes encompassing other cardiovascular complications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>A single-center retrospective study was conducted. We performed a multivariate analysis with a propensity score.

Total inhaled anesthesia was associated with a decreased requirement for inotropic medications (OR = 0.53, 95% CI 0.29\u20130.99, <jats:italic>p<\/jats:italic> = 0.04).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In our cohort, the Sedaconda-ACD device enabled us to achieve anesthesia without intravenous agents, and we did not observe any increase in postoperative complications.

However, in our cohort, the use of inotropic drugs was lower.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmed.2024.1340119","type":"journal-article","created":{"date-parts":[[2024,3,5]],"date-time":"2024-03-05T04:47:47Z","timestamp":1709614067000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Postoperative
