  • The Value of Tip Perfusion Index in the Diagnosis of Vascular Crisis after Replantation of Severed Digitals

    目的 探讨末梢灌注指数(TPI)在断指再植术后对血管危象早期诊断的价值。 方法 对2005年1月-2011年10月31例36个再植指运用Agilent V24C监护仪血氧饱和度探头进行持续TPI监测,同时观察记录术后再植指皮温、色泽、肿胀程度及毛细血管搏动情况,将发生血管危象的再植指分为危象组(n=4),将未发生血管危象的再植指分为对照组(n=32),分析发生危象前12 h至危象发生时的TPI,每2小时为一时间段,共7个时相,分别记为T1~T7。 结果 对照组各时间点TPI无明显变化,各时间点比较差异无统计学意义(P>0.05);危象组从T4开始,TPI呈逐渐下降趋势,与前一时间点比较差异均有统计学意义(P<0.05)。两组TPI在T1、T2、T3时比较差异无统计学意义(P<0.05);从T4开始,危象组TPI均较对照组降低,差异有统计学意义(P<0.05)。 结论 TPI监测能够无创、实时、灵敏地反映断指再植术后再植指血供情况,可早于临床症状以前对断指再植术后血管危象作出诊断,有较高的临床应用价值。

  • Regulations of VEP Changes in 30 Patients with Multiple Sclerosis

    Objective To study the regulations of visual evoked potential(VEP) changes in 30 patients with multiple sclerosis (MS). Methods VEP were performed in 30 MS patients,and the results were compared with normal subjects. Results The abnormality rate of VEP were 76.7%. 82.6% of patients with abnormal VEP showed clinical visual symptoms; 17.4% among those patients have no clinical visual symptoms. Conclusion  The rate of VEP abnormal in MS patients is more high. It may help more in the diagnosis of MS.
