Common important complication of acute renal failure

   Most acute renal failure after oliguria (or anuria), polyuria and recovery of the three stages of development of complications of acute renal failure in oliguria may occur are:
    (1) infection is the most common and serious complication, more common in severe trauma, burns due to high decomposition acute renal failure.
    (2) cardiovascular complications, including cardiac arrhythmias, heart failure, pericarditis, hypertension, etc.
    (3) the performance of the nervous system complications, headache, drowsiness, muscle convulsions, coma, seizures and so on. Neurological complications and retention in the body of toxins and water intoxication, electrolyte imbalance and acid-base balance disorders.
    (4) digestive complications manifested as anorexia, nausea, vomiting rugged, bloating, vomiting blood or blood in the stool, bleeding due to gastrointestinal mucosal erosions or ulcers caused by stress.
    (5) hematologic complications sharply decreased due to renal function, reduced erythropoietin can thus cause anemia, but most are not serious. Few cases due to reduced clotting factors, may have a bleeding tendency.
    (6) electrolyte imbalance, metabolic acidosis, hyperkalemia may occur, hyponatremia and severe acidosis, is one of the complications of acute renal failure is the most dangerous.
    In the urine of patients with daily urine output of up to 3000-5000ml, due to discharge large amounts of water and electrolytes, there may be dehydration, hypokalemia, hyponatremia, etc., if you do not replenish, patients can die from severe dehydration and electrolyte imbalance.
    Into the convalescent serum urea nitrogen, creatinine levels returned to normal, uremic symptoms subside, renal tubular epithelial cell regeneration and repair, the majority of patients with renal function can be fully restored, a small number of patients can be left under varying degrees of renal impairment.
