Relation Between Serum Sodium Trajectory and Survival in Septic Patients with Cardiopulmonary Bypass Surgery
This study examined the impact of serum sodium trajectory on 30-day mortality in septic patients after cardiopulmonary bypass (CPB) surgery using the MIMIC-IV database. Among 1,038 patients, serum sodium trajectories were classified into three groups, with higher levels linked to increased mortality. Elevated fluctuations, even within normal sodium ranges, were associated with adverse outcomes. These findings highlight the need for close monitoring and sodium management in critically ill patients undergoing CPB.
