静脉注射生理盐水与白蛋白可增加循环容量,并使尿钠排泄增加。另外,由于醛固酮与钠增加,数日后先出现浮肿,继向尿钠排泄增加,发生逸脱现象。尤其在ADH增多综合征。尽管有低钠血症,尿钠仍持续排出。这种情况下,可增加循环血容量,促使尿钠排出增多的因素为:1、肾小球滤过率上升。2、肾素、醛固酮系统受抑制。3、一种 Intravenous injection of saline and albumin can increase the circulation capacity, and urinary sodium excretion increased. In addition, due to increased aldosterone and sodium, a few days after the first edema, urinary sodium excretion followed by increase occurs escape phenomenon. Especially in ADH increased syndrome. Urinary sodium continues to be discharged despite hyponatremia. In this case, can increase circulating blood volume, urinary sodium excretion to promote increased factors: 1, glomerular filtration rate increased. 2, renin, aldosterone system inhibited. 3, a
