This study found that using crystalloid solutions with dopamine improved kidney function and reduced mortality in trauma patients compared to colloidal and crystalloid solutions alone. Early intervention with specific fluid regimens is crucial for preventing severe acute renal failure post-trauma.

Area of Science:

  • Trauma critical care
  • Nephrology
  • Intensive care medicine

Background:

  • Late-phase acute renal failure (ARF) post-severe trauma is a dangerous complication, often resistant to treatment and contributing to multiple organ failure.
  • Effective prevention strategies for ARF in trauma patients are critical for improving outcomes.

Purpose of the Study:

  • To investigate whether specific fluid resuscitation strategies can prevent late-phase ARF in severe trauma patients.
  • To compare the efficacy of two different fluid regimens on renal function, hemodynamics, and mortality.

Main Methods:

  • A comparative study involving two groups of severe trauma patients.
  • Study A: treated with colloidal and crystalloid solutions.
  • Study B: treated with crystalloid solutions and dopamine (continuous infusion at 3 µg/kg/min).

  • Renal function assessed using Goris score and creatinine clearance over 14 days.
  • Hemodynamics and cardiac function monitored daily.

    • Main Results:

    • Group B (crystalloid + dopamine) showed significantly lower mortality (44.7%) compared to Group A (60.6%) (P < 0.05).
    • While the incidence of renal impairment was similar, Group A had significantly more severe renal damage (18%) than Group B (2.6%).
    • Group B demonstrated better creatinine clearance and improved hemodynamic parameters, including higher cardiac index and lower pulmonary capillary wedge pressure.

    Conclusions:

    • Fluid resuscitation with crystalloid solutions and dopamine is more effective in preventing severe acute renal failure and reducing mortality in severe trauma patients compared to colloidal and crystalloid solutions alone.
    • The findings suggest that optimizing fluid volume and potentially incorporating vasoactive agents like dopamine can mitigate renal injury and improve survival post-trauma.
