Acute Renal Failure

The text outlines various renal conditions and their associated complications, treatments, and outcomes. It covers acute renal failure, transplant rejection, and complex conditions like myeloma kidney and thrombotic microangiopathies.

This is possible

Prognosis is bad

Toxemia of pregnancy

Abruptio placentae

Bactermia

Crescentic GN

30% have severe ARF

Prognosis



  • No Systemic Dz, Excellent recovery
  • Systemic Dz: High mortality

  • Rx:

  • Water/Electrolyte balance, Dialysis (Peritoneal or Hemo)
  • Rx
    Dialysis

    Peritoneal

    Hemo-

    Water/Electrolytes
    Toxic ATN

    Organic compounds

    CCL4

    Heavy Metals

    Arsenic

    Mercuric chloride

    Aminoglycoside

    Gentamicin

    Ischemic ATN
    Causes

    Reduced renal perfusion

    Leads to prerenal azotemia --> hence, elevated BUN & Cr

    Renal vasoconstriction

    Shock

    Hypovolemia

    Lab Values

    Oliguria 50%

    Gross

    Cortex pale, medulla dark

    Cortex bulging out of capsule
