脑干听觉诱发电位分级对脑创伤长期意识障碍患者预后评估的价值

Clinical value of brainstem auditory evoked potential grading to the evaluation of the prognosis in long-termcoma patients after traumatic brain injury.

目的通过对脑干听觉诱发电位(BAEP)的检测,探讨BAEP分级对长期昏迷脑损伤患者预后评估的临床价值。方法根据93例脑损伤后意识障碍超过2周的患者清醒前BAEP检测结果,将BAEP分为Ⅰ级、Ⅱ级和Ⅲ级。采用格拉斯哥预后评分(GOS)作为判断标准对患者的预后进行评估,并进一步分析BAEP分级与预后评估之间的关系。结果Ⅰ级的预后不良率为36.48%,Ⅱ级和Ⅲ级的总预后不良率为94.55%。分级与预后差异有统计学意义(P<0.05),分级越高,患者预后越差。结论 BAEP能客观敏感地反映中枢神经系统功能,因而BAEP分级科学地反映了不同程度的脑功能损伤,进而准确预测预后情况,具有较好的临床应用价值。
