  25. 25. Signs  (ARF) <ul><li>Lab values may change suddenly (within a few days to 2 weeks): </li></ul><ul><li>Urinalysis may be abnormal. </li></ul><ul><li>Serum creatinine may increase by 2 mg/dl or more over a 2-week period. </li></ul><ul><li>Creatinine clearance may be decreased. </li></ul>
  26. 26. Signs  (ARF) <ul><li>BUN may increase suddenly. </li></ul><ul><li>Serum potassium levels may be increased. </li></ul><ul><li>Arterial blood gas and blood chemistries may show metabolic acidosis . </li></ul>
  27. 27. Signs  (ARF) <ul><li>Kidney or abdominal ultrasound is usually the best test, but abdominal x-ray , abdominal CT scan or abdominal MRI may also reveal the cause of acute renal failure. Kidney size is usually normal or slightly large. </li></ul>
  28. 28. Signs  (ARF) <ul><li>Chemical tests of blood and urine may also help to distinguish the causes. A clean catch urine specimen will indicate if the cause is infection within the urinary tract. </li></ul>
  29. 29. Signs  (ARF) <ul><li>Renal angiography ( renal arteriography ) may be used to diagnose causes within the blood vessels of the kidney. </li></ul>
  30. 30. Signs (CRF) <ul><li>Blood pressure may be high, with mild to severe hypertension . A neurologic examination may show polyneuropathy. Abnormal heart or lung sounds may be heard with a stethoscope. </li></ul>
  31. 31. Signs (CRF) <ul><li>A urinalysis may show protein or other abnormalities. An abnormal urinalysis may occur 6 months to 10 or more years before symptoms appear. </li></ul><ul><li>Creatinine levels progressively increase. </li></ul>
  32. 32. Signs (CRF) <ul><li>BUN is progressively increased. </li></ul><ul><li>Creatinine clearance progressively decreases. </li></ul><ul><li>Potassium test may show elevated levels. </li></ul><ul><li>Arterial blood gas and blood chemistry analysis may show metabolic acidosis . </li></ul>
  33. 33. Signs (CRF) <ul><li>Changes that indicate chronic renal failure, including both kidneys being smaller than normal, may be seen on: </li></ul><ul><li>Renal or abdominal x-ray . </li></ul><ul><li>Abdominal CT scan . </li></ul><ul><li>Abdominal MRI . </li></ul><ul><li>Abdominal ultrasound . </li></ul>
  34. 34. Signs (CRF) <ul><li>This disease may also alter the results of the following tests: </li></ul><ul><li>Urinary casts </li></ul><ul><li>Renal scan </li></ul><ul><li>Pth </li></ul><ul><li>Serum magnesium - test </li></ul><ul><li>Erythropoietin </li></ul>
  35. 35. Care & Management (ARF) <ul><li>The goal of treatment is to identify and treat any reversible causes of the kidney failure (e.G., Use of kidney-toxic medications, obstructive uropathy , volume depletion). </li></ul>
  36. 36. Care & Management (ARF) <ul><li>Treatment also focuses on preventing excess accumulation of fluids and wastes, while allowing the kidneys to heal and gradually resume their normal function. Hospitalization is required for treatment and monitoring. </li></ul>
  37. 37. Care & Management (ARF) <ul><li>Your fluid intake may be severely restricted to an amount equal to the volume of urine you produce. You may be given specific dietary modifications to reduce build-up of toxins normally handled by the kidneys, including a diet plan high in carbohydrates and low in protein , salt, and potassium. </li></ul>
  38. 38. Care & Management (ARF) <ul><li>Antibiotics may be used to treat or prevent infection. Diuretics may be used to remove fluid from the kidney. </li></ul>
  39. 39. Care & Management (ARF) <ul><li>A major priority in treatment is to control dangerous hyperkalemia (increased blood potassium levels). A variety of different medications may be used, including IV ( intravenous ) calcium, glucose/insulin, and oral or rectal administration of potassium exchange resin (kayexalate). </li></ul>
  40. 40. Care & Management (ARF) <ul><li>Dialysis may be used to remove excess waste and fluids. This often makes the person feel better and may make the kidney failure easier to control. Dialysis may not be necessary for all people, but is frequently lifesaving, particularly if serum potassium is dangerously high. </li></ul>
  41. 41. Care & Management (ARF) <ul><li>Common symptoms that require the use of dialysis include decreased mental status, pericarditis , increased potassium levels, total lack of urine production, fluid overload, and uncontrolled accumulation of nitrogen waste products ( serum creatinine > 10 mg/dl and BUN > 120 mg/dl). </li></ul>
  42. 42. Care & Management (CRF) <ul><li>Treatment focuses on controlling the symptoms, minimizing complications, and slowing the progression of the disease. </li></ul>
  43. 43. Care & Management (CRF) <ul><li>Associated diseases that cause or result from chronic renal failure must be controlled. Hypertension , congestive heart failure , urinary tract infections , kidney stones , obstructions of the urinary tract, glomerulonephritis , and other disorders should be treated as appropriate. </li></ul>
  44. 44. Care & Management (CRF) <ul><li>Blood transfusions or medications such as iron and erythropoietin supplements may be needed to control anemia . Fluid intake may be restricted, often to an amount equal to the volume of urine produced. Dialysis or kidney transplant may be required eventually. </li></ul>
  45. 45. Care & Management (CRF) <ul><li>Dietary protein restriction may slow the build-up of wastes in the bloodstream and control associated symptoms such as nausea and vomiting . Salt, potassium, phosphorus, and other electrolytes may be restricted. </li></ul>
  46. 46. Complications (ARF) <ul><li>  increased risk of infections </li></ul><ul><li>gastrointestinal loss of blood </li></ul><ul><li>chronic renal failure </li></ul><ul><li>End-stage renal disease </li></ul><ul><li>Damage to the heart or nervous system </li></ul><ul><li>Hypertension </li></ul>
  47. 47. Complications (CRF) <ul><li>End-stage renal disease </li></ul><ul><li>Pericarditis </li></ul><ul><li>Cardiac tamponade </li></ul><ul><li>Congestive heart failure </li></ul>
  48. 48. Complications (CRF) <ul><li>Hypertension </li></ul><ul><li>Platelet dysfunction </li></ul><ul><li>Decreased immune response </li></ul>
  49. 49. Complications (CRF) <ul><li>Loss of blood from the gastrointestinal tract </li></ul><ul><li>Ulcers </li></ul><ul><li>Hemorrhage </li></ul><ul><li>Anemia </li></ul><ul><li>Hepatitis B , hepatitis C , liver failure </li></ul><ul><li>Decreased functioning of white blood cells </li></ul>
  50. 50. Complications (CRF) <ul><li>Increased incidence of infection </li></ul><ul><li>Peripheral neuropathy </li></ul><ul><li>Seizures </li></ul><ul><li>Encephalopathy, nerve damage, dementia </li></ul><ul><li>Weakening of the bones </li></ul><ul><li>Fractures </li></ul>
  51. 51. Complications (CRF) <ul><li>Joint disorders </li></ul><ul><li>Changes in glucose metabolism </li></ul><ul><li>Electrolyte abnormalities including hyperkalemia </li></ul><ul><li>Decreased libido, impotence </li></ul><ul><li>Miscarriage , menstrual irregularities , infertility </li></ul><ul><li>Skin dryness, itching /scratching with resultant skin infection </li></ul>
  52. 52. Patient / Family Education <ul><li>Call your health care provider if decreased urine output or other symptoms indicate the possibility of acute renal failure. </li></ul><ul><li>Call your health care provider if nausea or vomiting persists for more than 2 weeks. </li></ul><ul><li>Call your health care provider if decreased urine output or other symptoms of chronic renal failure occur. . </li></ul>
