Elevated urea-to-creatinine ratio provides a biochemical signature of muscle catabolism and persistent critical illness after major trauma

Summary

This intensive care medicine study, published in 2019, examined the urea-to-creatinine ratio as a potential biochemical signature of muscle protein breakdown in trauma patients with prolonged critical illness. The authors suggest that elevated ratios may reflect persistent catabolic states and provide a clinically useful marker of muscle catabolism in this population. The findings contribute to understanding metabolic derangement in severe trauma and critical illness, as suggested by the title and journal context.

UK applicability

The study was conducted in a United Kingdom intensive care unit setting and directly applies to UK critical care practice and nutrition support protocols. The findings may inform strategies for detecting and managing muscle catabolism in trauma patients within UK NHS intensive care services.

Key measures

Urea-to-creatinine ratio; serum urea; serum creatinine; markers of muscle catabolism; duration and severity of critical illness

Outcomes reported

The study examined the urea-to-creatinine ratio as a biochemical marker of muscle protein catabolism in critically ill trauma patients. The research investigated whether this ratio could characterise persistent critical illness and predict clinical outcomes.
