创伤性颅脑损伤后血钠紊乱的危险因素与预后

目的探讨创伤性颅脑损伤发生血钠紊乱的危险因素以及对预后的影响。方法回顾性分析80例中、重型颅脑损伤病例资料。分析血钠紊乱的发生率,外伤性脑损伤后首次CT扫描时的伤情表现和意识状态。结果 36例发生血钠紊乱,20例表现为高钠血症,16例表现为低钠血症。血钠紊乱在硬膜下血肿、脑内血肿和弥散性轴索损伤的病例中发生率更高。弥漫性脑损伤的病例血钠紊乱的发生率比局限性脑挫裂伤组高。结论弥漫性脑损伤病例血钠紊乱的发生率比较高。局限性脑损伤与血钠紊乱的比例并没有相关性。

Risk factors and prognosis of serum sodium disorders in patients with traumaticcraniocerebral injury

Objective To explore the risk factors and prognosis of serum sodium disorders in patients with traumatic craniocerebral injury. Methods The clinical data of 80 patients with moderate and severe traumatic craniocerebral injuries were analyzed retrospectively. Incidence of serum sodium disorders, presence of injuries in the initial computed tomography Mter traumatic craniocerebral injury, and level of consciousness were analyzed. Results The incidence of sodium disturbances was 36%. 20 patients presented hyperuatremia and 16 hyponatremia. A greater incidence of sodium disorders was found in patients with subdural, intracerebral hematoma and with diffuse axonal injury. The incidence of sodium disorders among the patients with diffuse lesions was greater than in the group of patients with focal brain contusion. Conclusions The incidence of sodium disorders is higher for patients with diffuse traumatic brain injuries. No association is found between focal lesions and proportion of sodium disorders.
