Influence of COPD, Anion Gap, and Serum Creatinine on MV and Mortality in Sepsis

Overview

This study investigates the relationship between invasive mechanical ventilation (MV) and 28-day mortality in ICU sepsis patients, highlighting the modifying effects of chronic obstructive pulmonary disease (COPD), anion gap, and serum creatinine levels. Findings indicate that MV is associated with increased mortality, particularly in patients with elevated anion gap and lower serum creatinine.

Background

Sepsis is a major cause of mortality in ICUs, affecting millions globally each year. Mechanical ventilation is a critical intervention for sepsis management, yet its impact on patient outcomes remains debated. Understanding the factors that influence the MV-mortality relationship is essential for optimizing treatment strategies in this vulnerable population.

Data Highlights

Key Findings

• 75.3% of sepsis patients in the study received mechanical ventilation.
• 28-day mortality was significantly higher in the MV group compared to the non-ventilation group (56.0% vs. 29.5%, p < 0.001).
• MV was independently associated with increased 28-day mortality (adjusted OR 2.62, 95% CI 1.67–4.11, p < 0.001).
• Chronic obstructive pulmonary disease (COPD), anion gap, and serum creatinine significantly modified the MV-mortality association.
• Patients with elevated anion gap had an OR of 6.62 for increased mortality associated with MV.
• Lower serum creatinine levels were associated with an OR of 3.73 for increased mortality in the MV group.

Clinical Implications

Clinicians should carefully assess the risks associated with mechanical ventilation in sepsis patients, particularly those with elevated anion gap and lower serum creatinine. Individualized patient management strategies are essential to mitigate the adverse effects of MV.

Conclusion

The study underscores the complex relationship between mechanical ventilation and mortality in sepsis patients, emphasizing the need for tailored approaches in clinical practice to optimize outcomes.
