1 Towards Global Eminence Chronic Renal Failure Chronic Kidney Disease JIA LEE, RN, PhD College of Nursing Science Kyung Hee University

2 Definitions Chronic Kidney Disease (CKD): is defined as either kidney damage or GFR < 60 ml/min/1.73m2 for 3 months Chronic Renal Failure (CRF): irreversible kidney dysfunction with azotemia 3 months Azotemia: BUN >28mg/dl & Cr>1.5mg/dl End Stage Renal Disease (ESRD): uremia requiring transplantation or dialysis Glomerular Filtration Rate (GFR): the total rate of filtration of blood by the kidney Creatinine Clearance (CCr): the rate of filtration of creatinine by the kidney (GFR marker)

3 Stages of CRF (KDOQI Clinical Practice Guidelines) Stage Description GFR Level Normal Healthy kidneys 90 ml/min or more Stage 1 Stage 2 Kidney damage with normal or high GFR Kidney damage and mild decrease in GFR 90 ml/min or more 60 to 89 ml/min Stage 3 Moderate decrease in GFR Stage 4 Severe decrease in GFR Stage 5 Kidney failure 30 to 59 ml/min 15 to 29 ml/min Less than 15 ml/min or on dialysis

4 Etiology Diabetes mellitus (28%) Hypertension (25%) Glomerulonephritis (21%) Polycystic Kidney Diease (4%) Other (23%): Obstruction, infection, etc.

5 Uremia Retention of nitrogenous wastes Increased intracellular Na and water GFR below 50% of normal Azotemia Anorexia and lethargy Decreased mental acuity and coma Fatigue, nausea, vomiting, cold, bone pain, itch, shortness of breath and seizures Fibrinous pericarditis

6 Subjective Symptoms Nausea Loss of appetite Headache Lethargy Tingling in extremities

7 Renal Symptoms: Objective Hyponatremia Dry mouth Poor skin turgor Confusion, salt overload, accumulation of K with muscle weakness Fluid overload and metabolic acidosis Proteinuria, glycosuria Urine = RBC s, WBC s, and casts

8 Cardiovascular Symptoms Hypertension Arrythmias Pericardial effusion CHF Peripheral edema

9 Neurological Symptoms Burning, pain, and itching, paresthesia Motor nerve dysfunction Muscle cramping Shortened memory span Apathy Drowsy, confused, seizures, coma, EEG changes

10 GI Symptoms Stomatitis Ulcers Pancreatitis Uremic fetor Vomiting Constipation

11 Respiratory Symptoms Increased chance of infection Pulmonary edema Pleural friction rub and effusion Dyspnea Kussmaul s respirations from acidosis

12 Endocrine Symptoms Stunted growth in children Amenorrhea( 무월경 ) Male impotence Increased aldosterone secretion Impaired glucose levels R/T impaired carbohydrate(cho) metabolism Thyroid and parathyroid abnormalities

13 Hemopoietic Symptoms Anemia Decrease in RBC survival time Blood loss from dialysis and GI bleed Platelet deficits Bleeding and clotting disorders purpura and hemorrhage from body orifices, ecchymoses( 반상출혈 )

14 Skeletal Symptoms Muscle and bone pain Bone demineralization Pathological fractures Blood vessel calcifications in myocardium, joints, eyes, and brain

15 Skin Symptoms Yellow-bronze skin with pallor Pruritus Purpura Uremic frost Thin, brittle nails Dry, brittle hair, and may have color changes and alopecia

16 Lab results BUN indicator of glomerular filtration rate and is affected by the breakdown of protein. Normal is 10-20mg/dL. When reaches 70 = dialysis Serum creatinine waste product of skeletal muscle breakdown and is a better indicator of kidney function. Normal is mg/dl. When reaches 10 x normal, it is time for dialysis Creatinine clearance is best determent of kidney function. Must be a hour urine collection. Normal is > 100 ml/min

17 Lab results: Fluid Imbalance Sodium and water retention: CHF, hypertension, ascites, edema Enhanced sensitivity to extra-renal sodium and water loss Vomiting, diarrhea, fever, sweating Symptoms: dry mouth, dizziness, tachycardia, etc. Recommendations Avoid excess salt and water intake Diuretics or dialysis

18 Lab results: Metabolic Acidosis Decreased acid excretion and ability to maintain physiologic buffering capacity: GFR > 20 ml/min: transient moderate acidosis Treat with oral sodium bicarbonate Increased susceptibility to acidosis

19 Lab results: Hyperkalemia The kidneys are means which K+ is excreted. Normal is mEq/L, maintains muscle contraction and is essential for cardiac function. Both elevated and decreased can cause problems with cardiac rhythm Hyperkalemia is treated with IV glucose and Na Bicarb which pushes K+ back into the cell Kayexalate is also used

20 Lab results: Hypocalcemia With disease in the kidney, the enzyme for utilization of Vit D is absent Ca absorption depends upon Vit D Body moves Ca out of the bone to compensate and with that Ca comes phosphate bound to it. Normal Ca level is meq/l Hypocalcemia = tetany Treat with calcium with Vit D and phosphate Avoid antacids with magnesium

21 Lab results: Anemia Lack of erythropoietin production Bone marrow suppression: uremic poisons: leukocyte suppression - infection bone marrow fibrosis: elevated parathyroid hormone(pth) and aluminum toxicity from dialysis Increased bruising, blood loss (surgery) and hemorrhage Lab Abnormalities: Prolonged bleeding time, abnormal platelet aggregation

22 Treatment for CKD Lose weight (if overweight), and take regular exercise Stop smoking Reduce the amount of salt in the diet in order to help control the blood pressure Eat a healthy balanced diet Drink about 2 litres of fluid a day (2-litre is about 10 cups or 6 mugs). There is no benefit in drinking large amounts of fluid, except in people who get lots of urine infections, or in a few other special cases Consider buying an automatic blood pressure monitor to check the blood pressure at home Have an annual flu jab (influenza vaccination), and have the pneumonia (pneumococcal) vaccine once (talk to your GP about this)

23 Treatment for CKD Stage 1 & 2 BP should be treated carefully. If it is above 140/85, tablets are usually needed, and the aim is to get the blood pressure down to 130/80 or lower. Cholesterol should be checked, and some people will be advised to take a daily aspirin tablet. Blood test to check egfr should be performed once a year. If the urine tests show a lot of protein in the urine, or the kidney function is declining over time, the case will be discussed with a kidney specialist, or a referral may be made to a kidney specialist.

24 Treatment for CKD Stage 3 Treatment as in CKD stages 1 and 2, but with more careful monitoring for declining kidney function

25 Treatment for CKD Stage 4 & 5 Treatment as for CKD stages 1-3. Additionally, any medications should be reviewed, as the dose may need to be altered and some drugs may need to be avoided as they could damage the kidneys further. This should include prescribed drugs and any drugs bought at the chemist and complementary therapies. In CKD stages 4 and 5 it is usually necessary to get advice from a kidney specialist, especially in stage 5 because kidney failure may become life threatening

26 Treatment: Hemodialysis Vascular access Temporary subclavian or femoral Permanent shunt, in arm Care post insertion Can be done rapidly Takes about 4 hours Done 3 x a week

27 Treatment: Peritoneal dialysis Semipermeable membrane Catheter inserted through abdominal wall into peritoneal cavity Cost less Fewer restrictions Can be done at home Risk of peritonitis 3 phases inflow, dwell and outflow

28 Treatment: Transplant Must find donor Waiting period long Good survival rate 1 year 95-97% Must take immunosuppressant s for life Rejection Watch for fever, elevated B/P, and pain over site of new kidney

29 Nursing Diagnosis Excess fluid volume Imbalanced nutrition Ineffective coping Risk for infection
