What is acute renal failure

Acute renal failure was more than a few persons of urine-based, most have been oliguria, polyuria phase and recovery phase three stages, in particular, acute tubular necrosis show more and more typical.

Oliguria: urine output within 24 hours means less than 400 ml, or less than 17 milliliters per hour urine output, usually last for 1 to 2 weeks, but there are more than up to 4 weeks. Mainly as water intoxication, metabolic disorders, such as electrolyte imbalance, acid-base balance disorders, uremia. Water intoxication Changbiaoxianwei edema, and even then Pulmonary edema, cerebral edema, congestive heart failure; electrolyte disorders common with hyperkalemia, hyponatremia, hypocalcemia, high blood magnesium; acid-base balance mainly as metabolic acidosis. At the same time there is a negative balance of heat, can aggravate acidosis and uremia. Uremia is characterized by BUN, Scr increased rapidly, with nausea, vomiting, loss of appetite and other gastrointestinal reactions. Since all of these pathophysiological changes, often complicated by pulmonary infection, cardiac arrhythmia, nervous system damage and even death.

Polyuria of: oliguric period, renal blood flow and glomerular filtration rate increased, appeared more of urine, into the polyuria phase, but it does not mean that has been restored, because there is still time azotemia, renal tubular concentration function did not recover. Still water, electrolyte disorders. Performance for the 24-hour urine volume increased to 1500 ml or more, as many as 6,000 ml, of course, daily urine output is gradually increased, as long as the daily urine output was about 400 ml of urine that began to enter the multi-phase. Polyuria phase duration is about 7 to 14 days. Polyuria of renal function that began to recover, with the increase in urine output, oliguria of the various disorders gradually improved. But also prone to the negative water and electrolyte balance, such as dehydration, hypokalemia, hyponatremia, or have high blood calcium, and because long-term consumption of resistant patients decreased, may predispose to infection.

Recovery: After the entry of multi-urinary recovery, according to different patients, varying duration of recovery period, usually 3 months to 12 months. The regular presence of renal dysfunction, the majority can be completely back to normal, only a small number of residual renal dysfunction and may develop chronic renal insufficiency.

Treatment of acute renal failure principle is: mostly due to acute reversible failure of any treatment should be careful not to add damage. Oliguria focus on to minimize the oliguric phase of the various disorders, kidney disease should focus on to first base "to keep people", that is, save the sick, to prevent the death, removal of concrete are the primary factors, correct water and electrolyte and acid-base balance disorders, aggressive treatment of heart failure, arrhythmia, brain, stress ulcer bleeding and other serious complications, conditions are encouraged to take dialysis. Polyuria of treatment is to prevent negative electrolyte and water balance, up for what we lack, but also should prevent infection. In the oliguric phase should also ensure that patients have enough heat to add a long recovery because of the time, renal function should be protected from damage, can not be ignored. Traditional Chinese Medicine on the treatment of acute renal failure, mainly in polyuria and recovery periods, can promote the restoration and enhancement of patient body mass, mainly for the Qi and Yin Deficiency Zheng, Qi and Yin used method of increasing fluid Xuan Yong Sheng Mai Yin He Treatment, drugs such as American ginseng, Ophiopogon japonicus, Scrophulariaceae, raw Rehmannia, Radix. If the body can increase Semen Yang, Curculigo, Epimedium and other drugs. Treatment of the oliguric period, also reported according to the dialectical, according to Chinese medicine, "Dysuria" permit the treatment, but the results were not very sure, and not blindly use the euphorbia, Euphorbia, commercial land and other toxic substances, so as not to aggravate kidney damage.
