Renal Problems

Acute Renal Failure: rapid loss of renal function with progressive azotemia (accumulation of nitrogenous waste products such(prenominal) as urea nitrogen and creatinine in the daub). Uremia is the ensure in which renal function declines to the point that symptoms develop in triune body systems. oliguria, urinary output of less than cd ml/day. develops over hours or days with progressive elevations of lineage urea nitrogen (BUN), creatinine, and potassium with or without oliguria. Most ordinarily fol unkepts severe, lengthen hypotension or Hypovolemia or nephrotoxic element exposure. Types: Prerenal: overdue to factors external to the kidneys that reduce renal blood course & running to rock-bottom glomerular perfusion & filtration. These include hypovolemia, decreased cardiac output, decreased peripheral vascular resistance, vascular check, myocardial infarction, and burns. -Oliguria occurs as the kidneys react to the decreased blood f embarrassed by init iate 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 alter 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 own direct damage to the renal tissue, resulting in afflicted nephron function. This is usually caused by prolonged ischemi a, nephrotoxins (antibiotics, line of busin! ess 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 cutting glomerulonephritis and general lupus erythematosus may also cause ARF. Hemoglobin and myoglobin plosive consonant the tubules...If you motivation to get a full essay, order it on our website: OrderCustomPaper.com
