Massive diuresis after acute renal failure.

W O Richards, B Shin

    Critical Care Medicine
    |March 1, 1984
    PubMed
    Summary
    This summary is machine-generated.

    Severe polyuria occurred after hemorrhagic shock resuscitation, indicating persistent kidney tubule dysfunction. This occurred even after normal kidney filtration function returned, highlighting a specific post-shock complication.

    Area of Science:

    • Nephrology
    • Critical Care Medicine
    • Physiology

    Background:

    • Hemorrhagic shock can lead to acute kidney injury.
    • Resuscitation from shock aims to restore hemodynamic stability and organ perfusion.
    • Renal recovery post-shock is typically assessed by glomerular filtration rate (GFR).

    Observation:

    • A patient experienced profound polyuria (up to 2000 ml/h) following resuscitation from hemorrhagic shock.
    • The polyuria phase followed a transient period of oliguria (low urine output).
    • This excessive urination persisted despite the normalization of GFR.

    Findings:

    • The observed polyuria suggests significant renal tubular dysfunction.
    • Tubular dysfunction was present even when glomerular filtration had recovered.

  • This indicates a dissociation between glomerular and tubular function recovery.

    • Implications:

    • Renal tubular function may be a sensitive indicator of kidney recovery post-shock.
    • Standard GFR measurements might not fully capture the extent of renal recovery.
    • Further research is needed to understand and manage persistent tubular dysfunction after shock.
