To investigate the association between the serum Na+/K+ ratio in patients following cardiac arrest and the risk of ICU mortality, highlighting its potential significance as a prognostic marker.
Key Findings:
A U-shaped association was observed between the Na+/K+ ratio and ICU mortality, with higher Na+/K+ ratio significantly associated with reduced ICU mortality (adjusted OR = 0.75; 95% CI: 0.64–0.89), suggesting important clinical implications for risk assessment.
Interpretation:
The study identified a marked U-shaped relationship between the serum Na+/K+ ratio and ICU mortality among cardiac arrest patients.
Limitations:
The study is observational and may be subject to confounding factors, including potential biases inherent in such studies. Data is limited to a single database, which may affect generalizability.
Conclusion:
Routine assessment of the Na+/K+ ratio could facilitate risk stratification and inform clinical management, but further research is needed to validate these findings.
