Abstract：Objective To investigate the effects of brainstem reflex (BSR) and brainstem auditory evoked potential (BAEP) on prediction of awakening in the patients with long-term conscious disturbance (LTCD) after traumatic brain injury (TBI).Methods Seventy-five patients with LTCD after TBI who treated in our hospital from August,2013 to September,2015 served as the objects of study,and all the patients received BSR examination 1,7,15,30,60 and 120 days after admission to hospital and BAEP examination 7 days after admission to hospital.All the patients were divided into conscious group and unconscious group (including died and persistent vegetative state patients) according to consciousness status six months after the injury.The correlation of BSR and BAEP with patients' consciousness was analyzed.Results The grades of BSR and BAEP were negatively related to the conscious rate of patients with LTCD after TBI (r=-0.574,-0.667,P=0.008,0.005).The grade Ⅰ and grade Ⅱ of BSR served as the indicators that patients were likely to awake,and grade Ⅲ,grade Ⅳ as the indicators that patients were unlikely to awake,and their specificity and sensitivity were 87.50％ and 81.03％ respectively.The grade [of BAEP served as the indicators that patients were fikely to awake,and grade Ⅲ as the indicators that patients were unlikely to awake and their specificity and sensitivity were 95.67％ and 78.13％ respectively.Conclusion BSR and BAEP examinations were very helpful to predicting the awakening in patients with LTCD after TBI and provide the basis for clinical treatment of TBI.
