    Summary

    Early hemodynamic and metabolic monitoring using the Swan-Ganz catheter can predict patient survival after severe injuries. Key indicators like blood pressure and lactate levels offer early prognostic insights.

    Area of Science:

    • Critical care medicine
    • Trauma surgery
    • Cardiovascular physiology

    Background:

    • Severe injuries necessitate early prognostic indicators for effective management.
    • Hemodynamic and metabolic parameters are crucial in assessing patient outcomes.
    • The Swan-Ganz catheter provides valuable data for critical care monitoring.

    Purpose of the Study:

    • To identify early hemodynamic and metabolic predictors of survival in patients with severe injuries.
    • To evaluate the prognostic value of Swan-Ganz catheter data in trauma patients.
    • To correlate early physiological measurements with patient outcomes.

    Main Methods:

    • Prospective study of 50 patients with severe injuries over 3 years.
    • Utilized Swan-Ganz catheter for continuous hemodynamic monitoring.

  • Analyzed metabolic parameters including lactate/pyruvate ratio and serum glucose.

    • Main Results:

    • Significant differences in systolic blood pressure and shock index within 2 hours between survivors and non-survivors.
    • Higher cardiac index observed in survivors from the outset.
    • Elevated lactate/pyruvate ratio, serum glucose, and decreased base excess predicted favorable outcomes.
    • Enzyme and bilirubin differences emerged from the sixth day onwards.

    Conclusions:

    • Early hemodynamic and metabolic profiling in severe trauma patients can predict survival.
    • Swan-Ganz catheter data provides critical early prognostic information.
    • Lactate/pyruvate ratio, serum glucose, and base excess are valuable early metabolic predictors.
