Risk factors associated with surgical reintervention in postoperative cardiac surgery: is there an impact of intraoperative fluid balance?

Methods: Case‒control study nested in a historical cohort. Patients over 18 years of age in the immediate postoperative period of cardiac surgery were included, and unplanned surgical reintervention was evaluated as the primary outcome.
