目的采用间断节律闪光刺激技术,探讨红色滤片及图形滤片在视频脑电图中的临床应用价值.方法选取2013年3月至2014年3月在武汉市儿童医院行视频脑电图的358例患儿,采用间断节律闪光刺激光源,在红色滤片、点状滤片、常规白光3种条件下,对358例患儿进行闪光刺激检查,对其中光驱动反应(PDR)阳性、光阵发反应(PPR)阳性及光惊厥反应(PCR)阳性患儿在3种刺激条件下的检测结果进行对比分析.结果 29例PDR阳性患儿中,红色滤片、常规白光、点状滤片刺激下枕区同步节律波幅分别为(31.103±8.920) μV、(30.294±7.767) μV、(24.436士8.075)μV,点状滤片刺激引发波幅显著低于红色滤片、常规白光,差异均有统计学意义(t=2.983、2.815,P=0.003、0.008);而红色滤片刺激引发波幅与常规白光刺激比较,差异无统计学意义(t=0.368,P=0.710).17例PPR阳性患儿红色滤片刺激引出16例(94.12％),常规白光刺激引出10例(58.82％,且反应强度及持续时间落后于红色滤片刺激),另1例仅由点状滤片刺激引出.3例PCR阳性患儿在红色滤片或点状滤片刺激下更易诱发癫(癎)发作.结论将红色滤片及图形滤片应用于常规视频脑电图闪光刺激检测可以在减少患者眼部不适感的同时,不影响PDR,提高光敏性癫(癎)及癫(癎)伴光敏性反应的检出率.

Objective To evaluate the clinical efficiency of intermittent photic stimulation (IPS) with pattern and red color plastic plates in video-electroencephalography(EEG).Methods Three hundred and fifty-eight patients hospitalized in Wuhan Children's Hospital from March 2013 to March 2014 were selected,and they were examined by using stroboscope with a red plastic plate,a dots printed plastic plate,and ordinary white flicker for photic driving response (PDR),photoparoxysmal responses (PPR),photoconvulsive response (PCR).The results of patients with PDR,PPR,PCR were analyzed.Results The PDR synchronously evoked by the three flickering patterns were in 29 cases,and the amplitude of photic drivings evoked by ordinary white flicker and red flicker were higher than that of flickering dot pattern [(30.294 ± 7.767) μV,(31.103 ± 8.920) μV vs (24.436 ± 8.075) μV],and there were significant differences(t =2.983,2.815,P =0.003,0.008).However,there was no significant difference between ordinary white flicker and red flicker (t =0.368,P =0.710).The PPR evoked were in 17 cases,and 16 cases (94.12％) of them were evoked by red color,while 10 cases (58.82％) wcre evoked by white light,and 1 case only evoked by flickering dot pattern.However,stronger intensity and longer duration time of PPR were evoked by red color than by white light.In 3 patients with positive PCR,the epileptic seizure was more likely to be evoked by red color or pattern plastic plate.Conclusions IPS with red and pattem plastic plate is more potent in eliciting photosensitive epilepsy in video-EEG than the ordinary white light.Moreover,it could reduce the discomfort of eyes without influencing PDR in comparison to the ordinary white light.
