目的:探讨原发性肝癌术后低钠血症发生的机理及治疗方法。资料:我科自1997年至1999年间共收治肝癌273例。术后出现低钠血症者158例,发生率58%。结论:血钠>120mmol/L者称稀释性低钠血症,原因为术后发生钠水潴留且水的潴留大于钠的潴留;血钠<120mmol/L者称衰竭性低钠血症,原因以细胞能量代谢障碍为主。针对不同类型的低钠血症应采取不同的治疗措施。
Objective: To explore the mechanism and treatment of hyponatremia after primary hepatocellular carcinoma. Information: 273 cases of liver cancer were treated in our department from 1997 to 1999. Hyponatremia occurred in 158 cases after the occurrence of 58%. Conclusion: Serum sodium>120mmol/L is called dilute hyponatremia because of postoperative sodium and water retention and water retention is greater than sodium retention; serum sodium <120mmol/L is called failure hyponatremia. Cell-based energy metabolism disorders dominate. Different treatment measures should be taken for different types of hyponatremia.
