Oliguria view of the liquid should be "measured for the" principle. Equivalent to the volume of liquid a day the day before would increase the amount of urine, vomiting, drainage, etc. and 500 ml (for not less dominant water loss in the Health and water). Oliguria of hyperkalemia is the main reason of death, it is necessary to strictly limit the high potassium food and drugs, active infection control, to prohibit the importation of obsolete inventory of blood. 5% sodium bicarbonate solution to correct metabolic acidosis and a first-aid measures to correct hyperkalemia. Static points in the glucose solution within a common insulin, to promote glycogen synthesis of potassium into cells. Application of 10% calcium gluconate 10 ~ 20 ml intravenous injection, can be antagonistic to the cardiac toxicity of high-K and correct hypocalcemia. Emergency treatment of acute renal failure is the most effective measures adopted dialysis therapy, including peritoneal dialysis, hemodialysis; simple ultrafiltration and (or) sequential ultrafiltration; continuity arteriovenous blood filtration and continuous arteriovenous dialysis and hemofiltration; blood Reperfusion; plasma exchange; adsorption hemodialysis. These technologies are indications dialysis and taboos of its pros and cons of. According to choose specific circumstances. To hemodialysis and peritoneal dialysis mainly peritoneal dialysis method is simple, security, economic, easy to carry out at the grass-roots hospitals. More attention should be paid to prevent the urine of dehydration, but the infusion of not more than, or more extended period of urine. In particular, more attention should be paid during the period of urine electrolyte imbalance, especially hypokalemia. More than a week after the urine of kidney function gradually restored, dietary protein intake can be increased gradually, the body is conducive to the resumption of renal cell repair and regeneration. Convalescence, do not need special treatment, avoid the use of renal toxicity of drugs, surgery and recovery period to avoid injury, pregnant women should be prohibited, every 1 to February periodic review of renal function.
