目的 探讨急性期脑卒中病人的P30 0电位变化 ,寻求判断此类患者认知功能的客观指标。方法 对 6 0例单一首发病灶的脑卒中病人和 6 2位健康者分别进行了P30 0电位测定 ,并将结果加以比较。结果 脑卒中组P30 0电位成分中N2 、P3 波潜伏期延长 ,P3 波幅降低 ,与对照组相比差异存在显著性 (P <0 0 5 ) ,而N1、P2波潜伏期两组相比差异未见显著性 (P >0 0 5 )。结论 P30 0电位对判定脑卒中患者的认知状况以及制定合理的治疗方案有重要的临床价值。
Objective To investigate the changes of P30 0 potential in patients with acute stroke and seek objective indexes to evaluate the cognitive function of these patients. Methods Sixty stroke patients with a single primary lesion and 62 healthy controls were tested for P30 potential, and the results were compared. Results Compared with the control group, the latency of N2 and P3 wave in P30 potentials of stroke group was prolonged and the amplitude of P3 was decreased (P <0.05), but there was no significant difference between N1 and P2 wave latency in stroke group Significance (P> 0.05). Conclusions The P30 potential has important clinical value in judging the cognitive status of stroke patients and formulating a reasonable treatment plan.
