The acute phase of the major complications of congestive cycle of a serious state of hypertensive encephalopathy and acute renal failure. Along with the prevention and control work in recent years to strengthen its incidence and mortality has decreased significantly. 1. Cycle of congestive Status: because Shuinazhuliu, blood volume dried up, until pulmonary edema. Each reported incidence varies with the severity, treatment-related. China reported 50 to 60 years to be hospitalized children with acute nephritis 24% to 27% of such complications to see, in recent years, the report has dropped to 2.4 percent. Many occurred in the onset of acute nephritis after 1 to 2 weeks. Clinical performance for the short breath, not sits flat chest tightness, coughing, lung wet-end audio, liver great tenderness, Benma law, and other symptoms of heart failure around, the result caused by expansion of blood volume, and cardiac pumps dried up and really different. At this time of a stroke more often and are not reduced, the normal cycle time, moving no more blood oxygen difference, and digitalis type shot in the arm to poor efficiency, and the application of diuretics often to ease. Very few can develop severe to the real heart failure, in a few hours to 1 to 2 days of rapidly emerging and life-threatening pulmonary edema. 2. Hypertensive encephalopathy: that blood pressure (especially the diastolic blood pressure) dramatically increased, in terms of a central nervous system symptoms. General多见children than adults. Generally believe that this disease is systemic hypertension on the basis of resistance to the brain caused small vasospasm cerebral hypoxia caused cerebral edema, but some people feel that is a sharp increase blood pressure, cerebral vascular with the regulatory function of the automatic systolic and diastolic out of control, A high degree of cerebral vascular congestion, also a result of cerebral edema, acute nephritis the Shuinazhuliu also play a role in the pathogenesis. Many occurred in the early course of acute nephritis, a general acute onset, severe headache for the performance, frequent nausea and vomiting, followed by visual disturbances, confusion, double vision, temporary and Mongolia, and lethargy or irritability, if not timely Treatment occurred convulsions, coma, a small number of temporary hemiplegia aphasia, when severe cerebral hernia. Nervous system have no limitations signs, light reflection and tendon reflexes may weaken or disappear, sometimes ankle clonic positive, but also a reflection pathology, may have serious signs and symptoms of cerebral hernia. Fundus examination common retinal arteries spasm, and sometimes the foreseeable edema optic papilla. CSF Qingliang, pressure and protein in normal or slightly increased. Such as blood pressure more than 18.7/12.0 kPa (140/90mmHg), and with visual impairment, convulsions and coma for three to a diagnosis. 3. Acute renal failure: a significant portion of children with acute nephritis in the acute phase have varying degrees of azotemia, but the progress for acute renal failure, only a very small number. Complications is still lack of effective preventive measures, acute nephritis has become the leading cause of death. Clinical manifestations of oliguria or urine, blood urea nitrogen, serum creatinine increase, hyperkalemia, metabolic acidosis. Oliguria or urine for three to five or more than one week, then increase the amount of urine, the symptoms disappeared, kidney function gradually resumed. 4, secondary bacterial infection, acute nephritis due to lower body resistance and easy to secondary infection, the most common is the lung and urinary tract infection, in case of secondary infection, should be actively symptomatic treatment, so as to avoid the original disease Heavier.
