Effect Of Intermittent Photic Stimulation Test And Hyperventilation Test On The Outcome Of Video EEG In Children With Epilepsy

Objective To investigate the effect of intermittent photic stimulation(IPS) test and hyperventilation(HV) test on the outcome of video EEG in children with epilepsy.Method 188 cases of video EEG which was diagnosed as pediatric epilepsy, were collected from Fujian Provincial Hospital department of pediatric internal medicine(ranging in time from January 2014 to February 2016), 116 cases were male, 72 were female; Age ranged from 2-13(mean 6.49±3.03)years, clinical diagnosis is pediatric epilepsy. According to whether execute the induced tests or not, all of the cases were divided into natural control group and induced tests group, the effect of the induced tests on the outcome of video EEG of children with epilepsy was observed; According to whether the duration of hyperventilation test is up to standard or not, the cases in induced tests group were divided into up to standard group and not up to standard group, the effect of the duration of hyperventilation test on the outcome of video EEG of children with epilepsy was observed; Compare the outcomes of video EEG of children with epilepsy between the natural control group and the up to standard group(IPS test included), and observe the the effect of the standard induced tests on the outcome of video EEG in children with epilepsy.Results 1. There were 64 cases(41 males and 23 females) in the natural control group, 41 cases were positive, 23 were negative, the positive rate was 64.06%. There were 124 cases(75 males and 49 females) in the induced tests group, 97 cases were positive, 27 were negative, the positive rate was 78.23%. There was no significant difference in the proportion of male and female between the natural control group and the induced tests group, and the difference of the positive rate of Video EEG wasstatistically significant(p<0.05). 2. There were 62 cases(38 males and 24 females) in not up to standard hyperventilation test group, 43 cases were positive, 19 were negative, the positive rate was 69.35%. There were 62 cases(37 males and 25 females) in up to standard hyperventilation test group, 54 cases were positive, 8 were negative, the positive rate was 87.09%. There was no significant difference in the proportion of male and female between not up to standard group and up to standard group, and the difference of the positive rate of video EEG was statistically significant(p<0.05). 3. There were 64 cases(41 males and 23 females) in the natural control group, 41 cases were positive, 23 were negative, the positive rate was 64.06%. There were 62 cases(37 males and 25 females) in up to standard hyperventilation test group, 54 cases were positive, 8 were negative, the positive rate was 87.09%. There was no significant difference in the proportion of male and female between natural control group and up to standard hyperventilation test group, and the difference of the positive rate of video EEG was statistically significant(p<0.01).There were 64 cases(41 males and 23 females) in the natural control group, 41 cases were positive, 23 were negative, the positive rate was 64.06%. There were 62 cases(38 males and 24 females) in not up to standard hyperventilation test group, 43 cases were positive, 19 were negative, the positive rate was 69.35%. There was no significant difference in the proportion of male and female between natural control group and up to standard hyperventilation test group, and the difference of the positive rate of video EEG was not statistically significant(p>0.05). 5.In addition, the degree of cooperation between the age of subjects and the hyperventilation test showed positive correlation within a certain range in my study.Conclusion The positive rate of video EEG in children with epilepsy can be improved by intermittent photic stimulation test and hyperventilation test; The positive rate of the outcome of video EEG in children with epilepsy was improved when the duration of hyperventilation test was up to standard; The positive rate of video EEG in children with epilepsy was significantly improved by intermittent photic stimulation test andstandard hyperventilation test; The positive rate of video EEG in children with epilepsy was not significantly improved by intermittent photic stimulation test and not up to standard hyperventilation test; The younger subjects are more difficult to cooperate with the hyperventilation test, the older subjects are more willing to cooperate with the hyperventilation test.
