Early serum sodium variability and mortality in critically ill patients with cerebral infarction: a retrospective cohort study

Key Points

• The aim is to determine the relationship between early serum sodium variability and short-term mortality in critically ill patients with cerebral infarction.
• Retrospective cohort design
• Analysis of serum sodium levels
• Monitoring of critically ill patients with cerebral infarction
• Early serum sodium variability identified as an independent predictor of short-term mortality
• Increased variability correlated with higher mortality rates
• Dynamic stability of sodium levels suggested as a therapeutic target
