CARE OF THE KIDNEY TRANSPLANT RECIPIENT (Cadaveric and Living Donor) Kimberly Kenney Nurse Clinician November 12, 2009 OBJECTIVES Upon completion of this lesson you will be able to: Identify leading causes of end stage renal disease Describe expected physical findings in a stable postop kidney recipient Identify problems with the foley catheter and implement appropriate interventions Administer correct I.V. fluids to replace urine output Manage a hypertensive recipient Identify signs and symptoms of post-op complications State purpose and side effects of prograf and neoral THE KIDNEY Each processes 1700L of blood per day Nephron is functional unit and has glomerulus Glomerulus is where materials are selectively reabsorbed or filtered Large blood flow needed for efficient GFR FUNCTIONS OF THE KIDNEY Regulate sodium and potassium Regulate pH Eliminate urea and uric acid Eliminate certain drugs Secrete renin Erythropoietin production Activate vitamin D CREATININE Reflects glomerular filtration rate and renal function Filtered in glomeruli, but NOT reabsorbed into blood If the creatinine doubles this indicates that the kidney function is reduced in half If the GFR is less than 5% then hemodialysis or a kidney transplant is needed for survival LEADING CAUSES OF END STAGE RENAL DISEASE IN US Polycystic kidney disease Glomerulonephritis Diabetes Hypertension Polycystic Kidney Disease Results from autosomal dominant inherited trait Genetic mutation on chromosomes 4 & 16 Fluid filled cysts form on functioning nephrons Tubular dilatation occurs Kidneys become enlarged Slow progressive renal failure CLINICAL MANIFESTATIONS AND DIAGNOSIS Pain from enlarging cysts Gross hematuria Infected cysts from UTI HTN from compression on vessels Diagnose with CT scan, ultrasound, genetic workup GLOMERULONEPHRITIS Inflammation of glomerulus Can be primary condition Can result from diabetes, lupus, viral infection, staph, or streptococcus Many cases have immune origin GLOMERULONEPHRITIS Nephritic Syndrome Inflammatory process damages capillary wall and decreases permeability RBCs in urine, decreased GFR, nitrogenous waste in blood, oliguria, water retention, HTN Glomerulonephritis Nephrotic Syndrome Inflammatory process increases capillary permeability Massive loss of protein and lipids in urine Edema due to Na and H20 retention and decreased albumin Dyspnea due to water retention GLOMERULONEPHRITIS Nephrotic Syndrome (cont.) Infection due to loss of globulins Drug toxicity since binding proteins are lost Thrombotic complications Atherosclerosis due to liver producing lipoproteins DIABETES Glomerulus is commonly affected structure Elevated glucose alters development of glomerular membrane Leads to thickening and sclerosing of glomerulus Elevated glucose may increase capillary pressure Large proteins escape Tubules overworked and nephrons destroyed HYPERTENSION Cause and effect of kidney function Sclerotic changes in glomerular structures Vascular structures thicken and perfusion decreases Nephrons less able to concentrate urine FACTORS CONSIDERED DURING TRANSPLANT WORKUP Basic lab work ABO bloodtyping Hepatitis and HIV screening Cardiovascular workup Psychiatric history Metastatic history Current infection Drug abuse THE TRANSPLANT PROCEDURE ASSESSMENT Dressing intact Jackson-Pratt drain Urine output at least 100 mL/hr Urine bloody at first, but clears with hydration Look for any clots, complaints of feeling full, sudden drop in urine output ***MD or NP ONLY ONES who flush foley FLUID REPLACEMENT D5 ½ normal saline at 50 mL/hr for maintenance Replace urine output mL per mL with 0.45% normal saline BLOOD PRESSURE REGULATION Too high: urine leak and bleeding Too low: vascular thrombosis and ATN Systolic should be 110-160 Consider pain management Labetolol and hydralazine Avoid ACE inhibitors ***Ca+ channel blockers increase cyclosporine levels OTHER POST-OP CONSIDERATIONS Wean for extubation Pulmonary toileting SCDs Labs Donor information kept confidential POU or Transplant ICU POST-OPERATIVE COMPLICATIONS Bleeding Sanguinous drainage on dressing or in JP Bloody urine continues despite hydration Increasing abdominal pain Firm, distended abdomen Ultrasound ordered to rule out bleed Possible return to OR POST-OPERATIVE COMPLICATIONS Urine Leak Increased yellow serous drainage in JP or on dressing Check creatinine of JP drain Decreased urine output in foley bag Increased serum creatinine Ultrasound to rule out leak Possible return to OR POST-OPERATIVE COMPLICATIONS Acute Tubular Necrosis (ATN) Due to ischemic injury or preservation injury Oliguric or anuric Urine appears very concentrated or bloody Increased serum creatinine Days to weeks to resolve Hold prograf and neoral Hemodialysis POST-OPERATIVE COMPLICATIONS Vascular Thrombosis Urine output suddenly drops Tenderness over graft site Increased serum creatinine Ultrasound done to view vessels Possible return to OR POST-OPERTIVE COMPLICATIONS Infection Post-op cephalosporin Check CMV status of patient before giving blood Hand washing and being mindful of environment IMMUNOSUPPRESSION Prograf OR Neoral (NOT BOTH) Simulect 20mg in OR Solumedrol 1000mg in OR Solumedrol taper post-op Prograf (tacrolimus)/Neoral (cyclopsporine) Prevent rejection Inhibit T-lymphocytes Doses based on trough and renal function Troughs drawn 6am and 6pm Cardizem CD given with Neoral to potentiate level SIDE EFFECTS ***Hypomagnesmia*** Hyperkalemia Hyperglycemia Hypertension Tremors Nephrotoxicity Neurotoxicity dyslipidemia QUESTIONS ????????
