抗利尿激素不适当分泌综合征(SIADH)的慢性型在小儿中少见。作者报告了3名慢性SIADH,一般地讲,泌尿异常起因于肾功改变或抗利尿激素(ADH)分泌紊乱,ADH分泌紊乱可进一步细分为原发性和继发性缺陷两种。原发性缺陷一般称为SIADH,由于持续的抗利尿作用,不能为已知的任何一种ADH释放因素(低血容量、低血压、高渗透性)的生理性刺激所引起,而继发性缺陷至少存在一种可识别的生理性因素。SIADH是儿科病中可识别的并发症,常见于中枢神经系统的感染、肿瘤、神经 Chronic forms of antidiuretic hormone inappropriate secretion syndrome (SIADH) are rare in children. The authors report three chronic SIADH. In general, urinary abnormalities result from changes in renal function or disturbances in the secretion of antidiuretic hormone (ADH), which can be further subdivided into primary and secondary defects. The primary defect, commonly known as SIADH, can not be caused by physiological stimuli known as any of the ADH release factors (hypovolemia, hypotension, hyperosmolarity), while secondary There is at least one identifiable physiological factor for defects. SIADH is a recognized complication of pediatric diseases, common in the central nervous system infections, tumors, nerves
