How to identify the cause of acute renal failure classification

Correctly distinguish the cause of acute renal failure classification, the choice of treatment is important. Specific points: ① According to history, detailed analysis of specific content as mentioned above. ② oliguria period in accordance with changes in the urine to be identified, play an important role. ③ kidney examination: Kidney ago of a parabola-shaped, but may appear after the infusion excretion; kidney of a low-level graphics, transfusion after no change; kidney after the secretion of the continuing increase of 15 minutes did not drop, does not change after rehydration . ④ should carefully distinguish between the former acute renal ischemic acute renal failure and renal necrosis, which often causes similar, there are insufficient blood volume, sometimes the opposite treatment programmes, such as the former should rehydration to expansion, while the latter should be restricted to water, sodium. In addition to these specific methods, the following three tests: Rehydration test: if in one hour, added to 1,000 milliliters of liquid, urine output increased to 40 ml / hour for the kidney before, if the blood volume has been corrected, still no urine output increase compared with tubular necrosis, should immediately stop Infusion; Mannitol test: if rehydration test not sure, in 5 to 15 minutes in the importation of 62.5 ~ 125 ml mannitol, an average of two hours in the urine of 40 milliliters per hour for the kidney before, or for tubular necrosis Should be suspended; Furosemide test: correct blood volume, not increase the amount of urine, can be 200 milligrams of intravenous furosemide, within two hours before the kidney to increase the amount of urine, or may not increase at five percent increase in 100 ml of glucose 500 Mg and 10 mg of furosemide dopamine, the loser in the end one hour, an increase of renal urine before, or for tubular necrosis, should be suspended. More than three tests should be used carefully, the former should prevent water poisoning, excessive expansion, from left heart failure, the latter two will speed up the tubular necrosis, once found no reaction, should be immediately suspended. More than three kinds of ways to prevent kidney or before the development of acute renal failure for ischemic tubular necrosis of the way, that distinction between the two, is of great significance. Relations to the success of the rescue.

How to identify chronic renal failure illusion

Chronic renal failure occurred in a variety of chronic kidney disease on the basis of the slow renal dysfunction, until the failure of a clinical syndrome (that is, as long as can cause kidney organic change the whole body or in part, the development of lesions eventually be To renal failure), the main performance is renal dysfunction, metabolic product of retention, water and electrolyte imbalance in acid-base balance, lead to kidney unable to maintain the stability of the human body environment. Chronic renal failure caused the cause is more complicated, in primary renal disease, the most common chronic glomerulonephritis of chronic renal failure incidence rate of more than half (about 50 - 70), chronic renal pelvis Yan accounted for about one quarter, there are other causes of renal arteriosclerosis; secondary kidney disease, common in diabetic kidney disease, systemic lupus erythematosus kidney disease, gout and kidney, and so on. Chronic renal failure in accordance with the degree of renal dysfunction, is divided into four, the first phase of renal failure decompensation (in a clinical serum creatinine in the 133 - 177 for the diagnosis, in this period may be no symptoms); section 2, is also called azotemia period of renal failure and renal insufficiency decompensated period, the general view of serum creatinine in the 186 - 442; third period for renal failure, Cr in the 451 -- 707 between the fourth and uremia period, Cr more than 707. Should arouse the attention of the friends of chronic renal failure is not to be fooled by the illusion, since the early CRF is not a typical performance, but also a system of any symptoms, therefore, easily mistaken for a certain system of diseases, especially those who do not have the obvious Patients with chronic kidney disease, such as a weakness, fatigue, physical decline, abdominal pain, diarrhea, vomiting or symptoms of gastrointestinal bleeding friends, and general weakness, looking pale, anaemia, skin itching symptoms to a doctor often can be mistaken for digestion Road disease, cancer, aplastic anemia, peripheral neuritis, and other diseases, delayed treatment, missed the best period in the treatment of life-long regret. If the above symptoms, should be approaching the hospital for specialist expert advice, to do a more systematic examination, the diagnosis is not difficult. Should be confirmed as soon as possible after treatment.
