Three times the symptoms of renal failure were different

Clinically, for the causes of renal failure, the disease is pided into two types, namely, acute renal failure and chronic renal failure. These two types of renal failure in the performance of the symptoms there are many similarities, in general, can be pided into the following three types. Here we specifically understand the symptoms of renal failure.

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 output 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.

Oliguria or anuria: renal tubular necrosis stage, adult 24-hour 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 1 month or less. Urine relative weight is relatively low and fixed, usually between 1.010 ~ 1.014, urine often protein, red blood cells and tube type. Bleeding tendency: platelet factor Ⅲ deficiency and defects, so that capillary fragility increased; liver damage, prothrombin time prolonged, often subcutaneous, oral mucosa, gingival and gastrointestinal bleeding, increased blood potassium and urea nitrogen increased , And even the emergence of disseminated intravascular coagulation. Metabolites accumulation: protein metabolites can not be excreted by the kidney, 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.

Water, electrolyte and acid base alkali imbalance: due to oliguria or anaerobic period of the body a lot of water can be expressed as nausea and vomiting, dizziness, sleepiness and even coma. Due to potassium proposed limited, rapid increase in serum potassium 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, the impact of calcium absorption, resulting in hypocalcemia, can lead to convulsions, increased hyperkalemia on myocardial damage The

The above description of the symptoms of renal failure were explained, these symptoms, such as irritability, fatigue, headache, etc., will seriously affect the patient's normal life and working conditions, over time, the patient may be interested in life and work may be further The cause of the patient's mental illness.
