Renal Problems

Acute Renal Failure: rapid loss of nephritic function with progressive azotemia (accumulation of nitrogenous waste products such(prenominal) as carbamide nitrogen and creatinine in the daub). Uremia is the ensure in which renal function declines to the point that symptoms develop in quaternate body systems. oliguria, urinary output of less than cd ml/day. develops over hours or days with progressive elevations of rent urea nitrogen (BUN), creatinine, and potassium with or without oliguria. Most ordinarily fol unkepts severe, lengthy hypotension or Hypovolemia or nephrotoxic element exposure. Types: Prerenal: payable to factors external to the kidneys that reduce renal blood course & function to decrease glomerular perfusion & filtration. These include hypovolemia, decreased cardiac output, decreased peripheral vascular resistance, vascular check, myocardial infarction, and burns. -Oliguria occurs as the kidneys act to the decreased blood f broken in by i nitiate the RAAS , which results in sodium and water conservation. Decreased renal perfusion overly decreases dynamic headroom of wastes (azotemia). As decreased perfusion continues, the kidneys lose their ability to lock up in compensatory mechanisms & intrarenal victimize to renal tissue occurs.

-The result is low urine output, a rise in BUN & blood serum creatinine proportionate to each other (ratio > 10:1), and the inability of the kidneys to uphold sodium. Intrarenal: conditions that arrange direct damage to the renal tissue, resulting in afflicted nephron function. This is usually caused by prolon ged ischemia, nephrotoxins (antibiotics, me! lody media, aminoglycoside), hemoglobin from hemolyzed RBCs, or myoglobin from necrotic muscle cells. Nephrotoxins can cause obstruction of intrarenal structures by crystallization or actual damage to the epithelial cells of the tubules. Primary renal diseases such as sagacious glomerulonephritis and general lupus erythematosus may also cause ARF. Hemoglobin and myoglobin evade the tubules...If you motivation to get a full essay, order it on our website: OrderCustomPaper.com
