Summary

Total reductive capacity (TORC) in serum can predict lethal outcomes in severe trauma patients. This novel assay effectively stratifies risk when traditional severity scores are insufficient, aiding in critical treatment decisions.

Area of Science:

  • Biochemistry
  • Trauma Medicine
  • Clinical Diagnostics

Background:

  • Effective risk assessment is crucial for managing severe injuries.
  • Traditional severity scores may not accurately predict lethal outcomes in trauma patients.
  • A novel assay measuring total reductive capacity (TORC) in serum was developed.

Purpose of the Study:

  • To evaluate the utility of a novel serum assay for total reductive capacity (TORC) in stratifying risk of lethal outcomes in severe trauma.
  • To determine if TORC measurements can predict patient outcomes when standard injury severity scores are non-discriminatory.

Main Methods:

  • Serum samples from severe trauma patients (Injury Severity Score > 19) were collected at the accident site and upon admission.
  • Total reductive capacity (TORC) was measured using a novel substrate-based assay involving fluorescent detection.

  • TORC levels were correlated with patient outcomes (lethal vs. survival).

    • Main Results:

    • Injury Severity Scores and Polytrauma Scores did not significantly differ between patients with lethal outcomes and survivors.
    • Patients with lethal outcomes exhibited significantly lower TORC levels at the accident site and upon admission compared to survivors.
    • TORC levels below 82.3 ng/mL at the accident site or admission were highly prognostic of a lethal outcome (88% sensitivity).

    Conclusions:

    • Serum total reductive capacity (TORC) provides a valuable biomarker for predicting lethal outcomes in severe trauma.
    • The TORC assay can stratify patient risk effectively, particularly when conventional severity scores are insufficient.
    • Early measurement of serum reductive potential aids in critical triage and treatment planning for severe trauma patients.
