目的评估经颅多谱勒超声(TCD)监测术中高强度短信号(HITS)数目能否预测术后神经心理功能变化的程度.方法 20例体外循环下行冠状动脉搭桥术的患者,术中采用TCD监测HITS的数值,神经心理学成套测验用于评定术后神经心理学功能的变化.结果术中HITS的数值与术后神经心理学功能的是否有变化无关.成套测验与HITS的数值的多因素相关分析中发现RW Dg1-DG5与HITS的数值有微弱相关.结论体外循环过程中HITS数值的变化与术后神经心理学功能变化无关.

Objective To evaluate whether the number of high intensity transient signals(HITS)intraoperative detected by transcranial doppler ultrasound(TCD)can predict postoperative neuropsychological deficit.Methods Twenty patients scheduled for coronary artery bypass grafting(CABG)operation with cardiopulmonary bypass were enrolled in this study.HITS were recorded by TCD intraoperatively.And neuropsychological test battery was used to assess postoperative neuropsychological changes.Results There was no significant difference in the number of HITS compared with patients with or without neuropsychological changes.And multivariable correlation between the test scores and the number of HITS showed there was a weak correlation between RW Dgt-Dg5 and HITS(P＜0.05).Conclusion The number of HITS detected during cardiopulmonary bypass(CPB) do not!correlate with the postoperative neuropsychologial changes.
