Normal osmoregulation is maintained by the proper function and interplay of factors influencing thirst, renal water metabolism, and vasopressin secretion. In pathophysiologic states, body water homeostasis is disrupted and hyponatremia ensures. Hyponatremia associated with cardiac failure, hepatic failure, respiratory failure, diabetes mellitus, the postoperative state, and other disorders is commonly found in the critical care setting. The pathophysiology, diagnosis, and treatment of hyponatremia are discussed.
正常的渗透压调节是通过影响口渴、肾脏水代谢和抗利尿激素分泌的因素的正常功能及相互作用来维持的。在病理生理状态下，机体水稳态被破坏，低钠血症随即发生。与心力衰竭、肝功能衰竭、呼吸衰竭、糖尿病、术后状态及其他疾病相关的低钠血症在重症监护环境中很常见。本文将讨论低钠血症的病理生理学、诊断及治疗。
