Renal failure in a child patient does not have anything like the performance?

How to understand a child suffering from kidney failure it is not there? Renal failure in a child patient does not have anything like the performance? We all understand a child's body resistance to disease is not as good as adults, so if not well protected, is let the disease there is a gap can be drilled, thereby affecting the health of a child is a child not benefit from the growth, then, you want to show as early as early treatment, renal failure patients is not the same period a child has what performance? 
Renal failure is a manifestation of renal function after injury gradually reduce, if not seize the time to control and treat it, very fast it will develop into renal failure uremia high creatinine, this time a little bit of loss of kidney function, become the body burden. The human body has two kidneys, usually a kidney on foot in order to maintain the normal operation of the human body, so in the early stages of kidney failure, usually without any performance to warn the patient's kidneys no method to work properly. When complete loss of kidney function has been close, the body changes and the performance of the patient's disease will be very obvious. Renal failure patient's symptoms will be different. 
Renal failure in a child patient does not have anything like the performance of renal manifestations have?: 
1, there is pre-renal, renal parenchymal renal diseases, such as after the onset of the original reasons for the rapid onset; 
2, oliguria: Continuous 3-14 days or longer, are described as the following situations: 
(A) no clinical urine or oliguria is characterized by daily urine output of less than 250ml or 1 hour urine output of less than 10ml of oliguria, urine output of less than 50ml per day for no urine; 
(2) the performance of azotemia and acidosis: weakness, mental apathy, lethargy, irritability, anorexia, vomiting, nausea and breathing deep, serious patients showed anemia, hiccups, mouth ulcers, gastrointestinal bleeding, coma and convulsions, etc.; 
(3) hyperkalemia: potassium if more than 7,0mmol / L, can be life threatening, slow heart rate, heart rate imbalances, low heart sound blunt or even arrest; electrocardiogram showed peaked T waves, QRS wave widened, P-wave flat wide. 
(4) high blood pressure, pulmonary edema and cardiac recession performance: difficulty breathing, cyanosis, rapid heart rate, cardiac enlargement, low heart sound blunt, with fine moist rales lungs, brain edema may have consciousness, coma, convulsions, etc.; 
(5) specific gravity is fixed at 1,010, there is protein, red blood cells, granular casts in the urine; 
(6) serum creatinine, phosphorus increased, blood calcium decreased, and some can show hands tetany. 
3, polyuria period: 
(A) polyuria in oliguria first or second week of the first weekend, the urine in a few days 400-600ml / d, part of a more moderate increase in severe cases of urine; 
? (2) large 羐  discharged a short time each day may be more than 3000ml) and the electrolyte can exhibit rapid dehydration and hypokalemia, hyponatremia phenomenon; 
(3) 5-7 days after the urine gradually returned to normal, but the kidney function is poor concentrated; 
(4) You can see most of the urine tube and white blood cells, red blood cells and a small part of the protein; 
(5) blood urea nitrogen (BUN) or NPN decreased slowly; 
(6) may predispose to infection. 
4, recovery: normal daily urine output, creatinine uremia high performance gradually disappeared, normal blood biochemical tests, renal function and proteinuria PRO take longer time to recover. 
The above is a kidney specialist hospital for children suffering from kidney failure was a very good child to explain, I hope this alert patients and parents, and the child has more than demonstrated performance when can seize the time to a regular hospital for examination and kidney disease treatment, which is good for the child.
