Objective:

To identify the minimum intravenous dose of sodium ascorbate required for optimal therapeutic benefit in sepsis and evaluate its effects on organ dysfunction, addressing the limitations of current treatments.

Key Findings:
  • High-dose sodium ascorbate (3.75 g/kg) rapidly reversed pathophysiological effects of sepsis in preclinical studies, with significant improvements in urine output and reductions in vasopressor requirements specifically linked to this high-dose treatment.
Interpretation:

Achieving high plasma ascorbate concentrations is crucial for multi-organ protection in sepsis, with potential variations in effective dosing across different physiological systems, highlighting the need for tailored approaches in clinical settings.

Limitations:
  • Study conducted in a preclinical ovine model, which may not fully translate to human physiology, and ethical considerations in animal research may limit broader applicability.
Conclusion:

High-dose sodium ascorbate shows promise in reversing organ dysfunction in sepsis, warranting further investigation in multicenter clinical trials to validate these findings in human subjects.
