Pre-renal failure Initial problem is above the kidney
Kidney is inadequately perfused resulting in kidney
tissue hypoxia and ischemic injury
Cause of pre-renal failure Hypovolemic shock
Vasodilation
Third spacing
Dehydration
Sepsis, DIC
CHF
Hypoxia of any origin
Pre-renal failure - at risk Post-surgical
Cardiac pathology
Trauma
Burns
Anaphylaxis
(ABOVE the kidney cause)
,S/S of pre-renal failure Oliguria < 400 ml/day
Anuria
Hypernatremia
Hyperkalemia
Hyperchloremia
Acidosis (low pH)
Increased nitrogenous wastes - azotemia
Increased BUN, increased creatinine
Management of pre-renal failure Not aimed at the kidney but at the underlying
cause. If the cause is corrected quickly, the renal
failure is corrected.
Best management is prevention → Fluids,
hydration, oxygenation
Intra-renal failure Problem within the kidney. Acute tubular necrosis.
Characterized by ischemic damage.
Causes of intra-renal failure Direct trauma to the kidney
Acute glomerulonephritis
Acute pyelonephritis
Hemoglobinuria
Myoglobinuria
Damage to other cells/tissues
Blood transfusion reactions
Nephrotoxins - chemicals, organic solvents,
pesticides
Venoms - copperhead and centipedes
Nephrotoxins - heavy metals, mercury, arsenic, lead
Nephrotoxins: Drugs
Nephrotoxic medications causing Aminoglycosides
intra-renal failure NSAIDs, acetaminophen
Antineoplastic agents
Vancomycin, neomycin
Cocaine
Lithium
Contrast media
Cyclosporine
, Contrast media Check creatinine before giving this because it shows
how well the kidney functions and how well the
kidneys can excrete this
S/S of intra-renal failure Oliguria < 400 ml/day
Anuria
Hypernatremia
Hyperkalemia
Hyperchloremia
Acidosis (low pH)
Increased nitrogenous wastes - azotemia
Increased BUN & Creatinine
Management of intra-renal failure Correct underlying problem (infections can be
problematic - cultures before antibiotics
Tubular membrane is intact
Patient survives imbalances
Post-renal failure Problem is obstruction either lower in the urinary
tract or elsewhere in the abdomen, external to the
renal/urinary system.
Management of renal failures Once the causative problem is removed or
corrected, the person must be supported while
renal function is diminished/absent
Tubular system in regenerating
- Adequate hydration
- Monitor fluid volume excess
- Diuretics (if not a kidney problem itself)
- Weigh daily
- Maintain accurate I&O
- Renal replacement therapy
Nursing Interventions for renal Monitor for potential causative agents
failures Medication administration and monitor effectiveness
Dietary restrictions
Strict I&O, weight
Supportive for patient and family
May need dialysis
