摘　　要：目的探讨脑导纳技术对急性脑损伤的诊断价值。方法对35例急性脑损伤患者进行双侧脑血流检测,与40例健康组对照,分析脑导纳图各项指标的特点及临床意义。结果外伤组脑供血量明显减少(ADLⅠ+Ⅱ指数减少),流入容积速度(HS/BS)下降,与对照组差异有统计学意义(P【0.05或P【0.01);治疗前后动态观察显示:病情恶化者脑导纳微分环波形渐变差,恢复者渐好转。结论脑损伤(3~21 d)的脑导纳图主要改变为:ADLⅠ+Ⅱ、及HS/BS减小,ADL IV及ADL IV/ADLⅠ+Ⅱ增大。提示病灶侧供血减少,血流缓慢。脑导纳图的动态观测对脑损伤的预后及疗效判断有一定的意义。Objective To explore the diagnostic value of the admittance technology on acute cerebral trauma.Method The bilateral cerebral blood-stream charts of 35 patients suffered from acute cerebral trauma were tested and compared to 40 healthy persons.Results The blood supply of cerebral trauma patients was less than the healthy persons(ADL I+II parameter decrease) and the HS/BS also cut down.It was significantly differing from the healthy ones(P<0.05 or P<0.001).The dynamic observation showsed the admittance differential loop wave forms of the deteriorated were getting worse while the ones of the recovered were getting better.(Conclusions The main) admittance changes of the cerebral trauma are the followings:ADL I+II and HS/BS are decreasing while ADL IV/ADL I+II is increasing.The focus blood supply is decreaced and the blood is slacked down.It is suggested that the admittance chart probably plays an important role in predicting judging the curing effect of cerebral trauma.
