Typical symptoms of acute renal failure

Experts pointed out that there are many causes of acute renal failure, and the incidence of rapid. Normal kidneys can discharge metabolites, to ensure the health of the human body, but the kidneys are damaged, can not work properly, posing a threat to human health. So, what are the symptoms of acute renal failure?
Kidney disease experts: acute renal failure symptoms
Hemorrhagic tendency: platelet factor Ⅲ deficiency and defects, so that capillary fragility increased; liver damage, prothrombin time prolonged, often subcutaneous, oral mucosa, gums and gastrointestinal bleeding, increased blood potassium and urea nitrogen , And even the emergence of disseminated intravascular coagulation.
Oliguria or anuria: renal tubular necrosis stage, adult 24 hours urine total less than 400ml for oliguria; less than 100ml for anuria. This period is generally 7 to 14 days, an average of 5 to 6 days, up to a month or less. Urine specific gravity is relatively low and fixed, usually between 1.010 ~ 1.014, urine often protein, red blood cells and tube type.
Metabolites accumulation: protein metabolites can not be excreted by the kidneys, nitrogenous substances accumulated in the blood and showed azotemia, manifested as blood urea nitrogen, creatinine increased. At the same time blood phenol, guanidine and other toxic substances also increased, the formation of uremia. Manifested as nausea, vomiting, headache, irritability, irritability, fatigue, lack of consciousness, and even coma and other symptoms.
Polyuria: oliguria or anuria after 9 to 14 days, such as 24 hours of urine increased to more than 400ml, that is, the beginning of polyuria, the general daily urine output up to 3000ml or more. This period of about 14 days, urine can suddenly increase, gradually increase or increase slowly, the latter poor prognosis. Polyuria renal function has not yet fully recovered, the main complication is hypokalemia and infection. After the polyuria patient weakness, there are still disorders and anemia, to be a few months to return to normal.
Water, electrolyte and acid base alkali imbalance: due to oliguria or anaerobic body of a large number of water can be expressed as nausea and vomiting, dizziness, sleepiness and even coma. Due to potassium limited, serum potassium can be rapidly increased arrhythmia, ECG abnormalities, and even cardiac arrest, accompanied by hypermagnesemia neurological symptoms, such as muscle weakness, coma, ECG abnormalities. Acute renal failure, renal excretion of phosphorus decreased, and turned to the intestinal excretion, and calcium does not dissolve calcium phosphate, affecting the absorption of calcium, resulting in hypocalcemia, can lead to convulsions, increased hyperkalemia on myocardial damage The
Acute renal failure must pay attention, and to be treated, it will not make the disease worse, and thus will not lead to other complications. Experts advise: If you find the above symptoms, we must timely medical treatment, so as not to affect the treatment of the disease, so that serious illness. Patients must go to a regular hospital for physical examination to ensure the accuracy of the diagnosis.
