Efficacy and safety of early prone position in postoperative cardiac surgery adults with acute respiratory distress syndrome: a single-center retrospective cohort study

Acute respiratory distress syndrome (ARDS) is a leading cause of postoperative respiratory failure after cardiac surgery, and the mortality rate is extremely high. Although prone positioning (PP) may be safe and effective for ARDS, it is still not widely adopted in cardiac surgery patients. We aimed to assess the efficacy and safety of early PP in ARDS after cardiac surgery.
