Learn some common sense of acute renal failure

In recent years, the incidence of kidney disease is relatively high, a serious threat to human health, but many people do not understand kidney disease have a lot of problems, kidney failure, kidney disease is the progressive development of the disease, kidney function loss of some or all of a pathological state. Acute renal failure, renal failure is relatively rapid onset of symptoms, in the short term kidney function in patients with a sharp decline, there was a series of clinical symptoms of kidney failure. Here to tell you about some of the common sense of acute renal failure, for your timely understanding.

Acute renal failure is a syndrome, is caused by a variety of causes, glomerular filtration rate is rapidly decreased to 50% of normal or less, and blood urea nitrogen and serum creatinine increased rapidly and cause the patient's body of water, electricity mass disorders and acid-base balance disorders and symptoms of acute uremia. Acute renal failure can be found in sections disease, acute renal failure and chronic renal failure is different, if early diagnosis, timely rescue, the renal function can be completely restored, if the delay in treatment, it is likely to be fatal. The prognosis of the primary disease, age, diagnosis and treatment sooner or later, whether to merge multiple organ failure and other factors.

Acute renal failure, some common sense understanding, diagnosis is based include:

1, there is shock hemolysis, drug toxicity or intravascular or allergies;

2, in correcting deficiencies or exclude acute hypovolemia, dehydration, urinary tract obstruction, urine output is still ≤17 / ml / h or urine still ≤400 / ml / 24h.

3, in the specific gravity 1.015 or less, and even fixed at 1.010.

4, abrupt onset and increasing azotemia.

5, urine osmolality <350mOsm / Kg.H2O, urinary sodium> 40mmol / L.

6, except pre-renal azotemia of renal after little or no urine.

Some clinical manifestations of acute renal failure is

1, oliguria (1) three low (sodium, calcium, pH decrease) three high (potassium, phosphorus, creatinine increase) a edema;

(2) uremic symptoms may include nausea, vomiting, gastrointestinal bleeding, difficulty breathing, coughing, chest pain, high blood pressure, heart failure, drowsiness, confusion, tremor and epileptic seizures, anemia and bleeding tendency and so on;

(3) infection according to the site of infection to produce symptoms.

2, polyuria period: renal failure and recovery, blood urea nitrogen and creatinine is still rising, and prone to dehydration, infection, hypokalemia, gastrointestinal bleeding.

3, recovery: near-normal blood urea nitrogen and creatinine, urine gradually returned to normal, more normal glomerular filtration rate within 3-12 months.

Treating acute renal failure

1, the general treatment: bed rest, adequate nutrition supplement;

2, maintenance of water, electrolyte and acid-base balance;

3, infection control sensitive antibiotics;

4, dialysis treatment, including hemodialysis hemofiltration or peritoneal dialysis;

5, promote renal tubular epithelial cell regeneration.

These are some of the common sense of acute renal failure in a brief introduction, I hope for your help.
