2016-12-29 19:10
The clinical manifestations of acute renal failure can be classified into three types:
(1) urinary type ARF is characterized by oliguria or non urine, which is usually followed by oliguria (or no urine), polyuria and recovery of the clinical stage of three. Oliguria period usually lasts 3 days ranging from -1 months, an average of about 10 days or so, less mainly as follows: urinary sodium and water retention: the performance of systemic edema. Higher blood pressure. Pulmonary edema, cerebral edema and heart failure often endanger life, is the leading cause of death of the original resistance; the electrolyte disorder including: hyperkalemia, hyponatremia, hypocalcemia and hyperphosphatemia; hyperkalemia is oliguria first cause of death; the metabolic acidosis: acid metabolite accumulation by in vivo, infection and tissue destruction can cause acidosis increased. Acidosis may manifest as nausea and vomiting, fatigue, lethargy, deep breathing, there may be severe shock, blood pressure decreased; the uremic symptoms: symptoms of poisoning toxins accumulate in the body caused by the systemic. The nitrification system includes anorexia, nausea, vomiting, abdominal distension, diarrhea; respiratory system including dyspnea, cough, chest pain, uremic pneumonia; circulatory system including arrhythmia; heart failure; nervous system including consciousness disorder, agitation, delirium, convulsions. The urine volume can reach 3000 to 5000mL per day, the serum urea nitrogen and creatinine decreased gradually, and the uremic symptoms gradually subsided. Polyuria due to a large number of water and electrolyte discharge, dehydration, hypokalemia, hyponatremia, etc., if not promptly added, patients can die of dehydration and electrolyte disorders. Enter the recovery period after the serum urea nitrogen and creatinine levels returned to normal, renal tubular epithelial cell regeneration and repair, the renal function recovered completely in about half a year to 1 years, a small number of patients can have varying degrees of renal impairment.
(2) the clinical manifestations of non oliguric part of ARF patients without oliguria or anuria, only for a short period of time the creatinine clearance rate decreased rapidly, decrease of the normal value below 50%, serum urea nitrogen and creatinine increased, serum creatinine increased daily rate of more than 44-88mmol/L, this type is not small urinary type ARF, the clinical manifestations are relatively mild, often misdiagnosed.
(3) high decomposition type ARF part of the cases occurred in the tissue catabolism extremely increased under the condition of daily blood urea nitrogen and creatinine increased speed >14.3mmol / L and >lUmol / L is called the high decomposition type ARF, usually in a large area of trauma; burns, surgery like and serious infection, performance the severe metabolic acidosis and electrolyte disorders, poisoning symptoms significantly, especially in the nervous system can be expressed as prominent, drowsiness, coma, convulsions, seizures, hyperreflexia or loss etc..
