目的:比较脑电图不同监测时长对癫痫及痫样发作患者病理性脑电改变的检出率。方法:选择125例癫痫及痫样发作的患者,行2 h 21导脑电图监测(国际10-20系统),比较记录开始后15 min、30 min、1 h及2 h的痫样放电及病理性慢波的检出率。结果:痫样放电检出率在记录15 min时为50.40%,30 min时为62.40%,1 h时为71.29%,2 h时为75.20%;1 h、2 h时痫样放电检出率高于记录15 min时(P<0.05),2 h时与1 h时差异无统计学意义。其中散在棘波、尖波、棘慢、尖慢复合波的检出率在记录15 min时为44.00%、30 min时为57.60%,1 h时为66.40%,2 h时为69.60%;其中,30 min、1 h、2 h时检出率大于记录15 min时(P<0.05),2 h时与1 h时差异无统计学意义。不同监测时长的阵发性慢波、局灶性慢波及弥散性慢波的检出率差异无统计学意义。结论:脑电图不同监测时长对癫痫及痫样发作患者的痫样放电,尤其是散在棘波、尖波、棘慢、尖慢复合波的检出率有明显差异;1 h及以上监测时长可明显提高对痫样放电及病理性慢波的检出率,监测2h与1h时的检出率无明显差异。 |

Abstract: |
Objective:To compare the yields of pathological discharges or waves in different electroencephalography (EEG) recording durations. Methods:One hundred and twenty five patients diagnosed with epilepsy or seizure like event in our hospital from May 2015 to May 2017 were enrolled. All the patients underwent a 2-hour 21-channel EEG examination (according to the international 10-20 system). Yields of epileptiform discharges (EDs) and pathological slow waves (SWs) were compared between the first 15 minutes, 30 minutes, 1 hour, and 2 hours in the recording duration. Results:The yields of EDs were 50.40% in the 15-min group, 62.40% in the 30-min group, 71.29% in the 1-h group, and 75.20% in the 2-h group. The yields of EDs in the 1-h and 2-h groups were higher than those in the 15-min group (P<0.05). No obvious difference was found between the 2-h and 1-h group. The yields of sporadic spikes, sharps, spike- and sharp-slow complexes were 44.00% in the 15 min group, 57.60% in the 30-min group, 66.40% in the 1-h group, and 69.60% in the 2-h group. The yields in the 30 min, 1-h, and 2-h groups were higher than those in the 15-min group (P<0.05). No obvious difference was found between the 2-h and 1-h groups. No significant differences were observed in the yields of paroxysmal, focal, and diffused SWs in different durations. Conclusions:Yields of EDs in different EEG recording durations differed significantly in patients with epilepsy and seizure-like event, especially for the sporadic spikes, sharps, spike- and sharp-slow complexes. One hour and over recording yielded a significant higher incidence of EDs. No obvious difference was found between the 1-h and 2-h recordings. |
