    Study Notes

    Acute Kidney Injury Classification

    • The RIFLE classification system categorizes acute kidney injury into risk, injury, failure, loss, and end-stage renal disease.
    • The pediatric RIFLE criteria assess kidney injury based on the percentage reduction in glomerular filtration rate, creatinine increase, and urine output.
    • The Kidney Disease Improving Global Outcomes (KIDIGO) combined RIFLE and AKIN classifications to establish a unified AKI classification in 2012.
    • KDIGO defines AKI as an increase in serum creatinine by 0.3mg/dL or more within 48 hours, or to 1.5 times baseline within the last 7 days, or urine output less than 0.5 mL/kg/h for 6 hours.
    • The stages of AKI are based on serum creatinine levels, urine output, and the need for renal replacement therapy.
    • Acute kidney injury can be classified into pre-renal, intrinsic renal, and post-renal causes.
    • Pre-renal causes include circulatory insufficiency, dehydration, sepsis, and heart failure.
    • Intrinsic renal causes involve direct renal parenchymal damage or dysfunction, including acute tubular necrosis and nephrotoxin exposure.
    • Post-renal causes result from obstructive processes that block urine flow, such as tumors or stones.
    • Differentiating between pre-renal and renal AKI involves assessing urine osmolality, specific gravity, sodium levels, and plasma creatinine and urea ratios.
    • Management of chronic kidney disease includes indications for dialysis, such as symptoms of uremia, fluid overload, calcium/phosphate imbalance, and hypertensive pericarditis.
    • Peritoneal dialysis, utilizing the body's peritoneum as a filter, can be performed through continuous ambulatory or continuous cycling methods, offering advantages in children and infants.
