目的:探讨急性脑卒中患者血钠异常症的发生及相关因素。方法:对146例血钠异常者检测,分析各种因素对血钠的影响。结果:急性脑卒中常有血钠异常,有高钠血症、低钠血症(有抗利尿激素分泌异常综征及脑性盐耗综合征等)等,表现复杂。低钠血症在老年患者多见,并与营养状况相关。结论:急性脑卒中常伴发血钠异常症,应及时监测、极早发现及治疗。 Objective: To investigate the occurrence and related factors of serum sodium abnormality in acute stroke patients. Methods: 146 cases of abnormal serum sodium were detected and analyzed the impact of various factors on serum sodium. Results: Acute stroke often has abnormal serum sodium, hypernatremia, hyponatremia (with anti-diuretic hormone secretion syndrome and cerebral salt consumption syndrome, etc.), the performance is complicated. Hyponatremia is more common in elderly patients and is associated with nutritional status. Conclusion: Acute stroke often associated with abnormal sodium, should be timely monitoring, early detection and treatment.
