颅脑损伤急性期血浆去甲肾上腺素水平的变化及其意义

目的 观察急性闭合性颅脑损伤患者伤后早期血浆去甲肾上腺素（ＮＥ）水平的变化。方法 结合有关临床资料，就颅脑损伤后ＮＥ水平的改变及其与颅脑损伤间的关系进行研究。结果 伤后１周后，颅脑损伤患者血浆ＮＥ水平显著高于对照组，且以３日内更明显，颅脑损伤患者血浆ＮＥ水平升高的程度和颅脑损伤的严重程度，颅脑损伤的类型及早期预后关系密切。结论 颅脑损伤后内过高水平的ＮＥ，可能在颅脑损伤后继发性损伤的发生发展过程中

The change of norepinephrine level of blood in the patients with acute brain injury

Objective To observe the norepinephrine (NE) level of 30 patients with acute brain injury.Methods The relationship between NE level and brain injury was studied.Results The results demonstrated that NE level in the patients with acute brain injury was remarkably higher than control group during the first week,especialy in the first three days.NE level was closely related to the severity,the types and the early prognosis of brain injury.Conclusion Elevated NE level may play an important role in the secondary brain injury.
