kidney anatomy, kidney, blood, urine flow, azotemia, prerenal, uremia, renal underperfusion, prerenal azotemia, abnormally high level of nitrogen-type wastes, in the bloodstream, conditions that reduce blood flow, kidneys, prerenal azotemia is relatively common, in hospitalized patients, kidneys, filter the blood, volume, pressure of blood flow, the kidney drops, blood filtration also drops drastically, not occur at, waste products remain, in the bloodstream, no urine is formed, though the internal structures, the kidney, intact, functional, lab tests show that nitrogen-type wastes, creatinine, urea, accumulating, azotemia, waste products act, poisons, they accumulate, damaging tissues, reducing the ability of organs to function, build-up of nitrogen waste products, accumulation of excess fluid, the symptoms of prerenal azotemia, acute renal failure, prerenal azotemia, most common form of kidney failure seen in hospitalized patients, condition that reduces blood flow, kidney, loss of blood volume, dehydration, prolonged vomiting, diarrhea, bleeding, burns, conditions that allow fluid to escape from circulation, volume is not lost, heart cannot pump enough blood, blood is pumped at low volume, increase risk, prerenal azotemia, conditions include shock, septic shock, heart failure, blood flow, kidney is interrupted, trauma, kidney, surgery of various types, renal artery embolism, renal artery occlusion, decreased, no urine produced, fatigue, decreased alertness, confusion, pale skin color, rapid pulse, dry mouth, thirst, swelling, additional symptoms, excessive urination at night, abdominal pain, an examination, signs of low heart function, signs of hypovolemia, blood pressure low, drop, the person stands up, pulse pressure, difference, systolic blood pressure, diastolic blood pressure, heart rate rapid, skin turgor poor, mucous membranes dry, neck veins collapsed, no urine, in the bladder, drained by a catheter, condition is prolonged, signs of acute kidney failure present, a urinalysis, decreased kidney function preserving the ability, the tubules, nitrogen wastes, electrolytes continue to be excreted, at abnormally low rates, urine sodium low, fractional excretion at less than 1%, urine creatinine to serum creatinine ratio is high, urine urea to serum urea, bun, ratio is high, fractional excretion of urea is low, osmolality, specific gravity show concentrated urine, blood lab tests show a rapid accumulation of nitrogen wastes, increased bun, increased creatine, increased bun/creatinine ratio, main goal of treatment, rapidly correct the cause, the prerenal azotemia, damage occurs, internal kidney structures, hospitalization, involve treatment in an intensive care unit, hemodialysis, peritoneal dialysis, intravenous fluids, blood, blood products, increase blood volume, after blood volume has been restored, medications, increase blood pressure, cardiac output, dopamine, dobutamine, similar cardiac medications, the decreased blood volume, blood pressure, symptoms of acute renal failure, it should continue, medications, dietary restrictions, dialysis, prerenal azotemia is reversible cause, cause is not corrected quickly, internal structures, the kidney, acute tubular necrosis, acute kidney failure, acute tubular necrosis, tissue death, symptoms indicating prerenal azotemia present, prompt treatment of any condition that reduces the volume, force of blood flow, the kidneys, prevent prerenal azotemia from developing.
