对３８例小儿急性肾小球肾炎（ＡＧＮ）早期同步作Ｘ线胸片和超声心动图等动态观察，首次检查平均病程４．４天。结果胸片３３例示循环充血，３２例心影增大，心胸比率５４％，平均４．８天恢复正常。超声心动图２２例左心房增大，１２例伴二尖瓣返流，分别于５天和６．１天后消失。３８例左心室功能均正常。以上改变和临床利尿消肿相平行。提示ＡＧＮ早期心血管容量的超负荷导致了胸片和超声心动图的改变，后二者可作为ＡＧＮ早期循环充血状态的常规监护手段。
Thirty-eight children with acute glomerulonephritis (AGN) early synchronous X-ray and echocardiography and other dynamic observation, the first check the average duration of 4.4 days. Results 33 cases of chest radiograph showed congestion, 32 cases of heart shadow increased, cardiothoracic rate of 54%, an average of 4.8 days returned to normal. Echocardiography in 22 cases of left atrial enlargement, 12 cases with mitral regurgitation, respectively, in 5 days and 6.1 days disappeared. 38 cases of left ventricular function were normal. The above changes and clinical diuretic swelling parallel. It is suggested that the overloading of early cardiovascular capacity of AGN leads to the change of chest radiography and echocardiography, and the latter two can be used as routine monitoring methods of AGN early circulatory hyperemia.
