不同时限视频脑电图对小儿癫痫患者的诊断价值研究

Study on the Diagnostic Value of Video Electroencephalogram with Different Time Limits for Pediatric Epilepsy Patients

摘要: 目的：探究不同时限视频脑电图对小儿癫痫患者的诊断价值。方法：择取本院90例小儿癫痫(2022.11~2024.11)患儿深入分析，均完善视频脑电图，于监测的30 min、1 h、3h、6 h、12 h、24 h行视频脑电波分析，分析其诊断价值。结果：本文纳入的90例患儿中，总阳性率为82.22%，其中阳性率最高时限为12 h，其次为3 h、24 h、6 h、1 h，30 min阳性率最低；在不同疾病类型中的脑电图特征有所不同；长达24小时或更长的监测时长并不能提高检出阳性率。结论：在对小儿癫痫患者诊断时，不同时限视频脑电图诊断中，3 h以上的监测时长能显著提升阳性率，其中12 h诊断阳性率最高，具有较高的诊断价值，可为患儿积极治疗提供可靠依据。长达24小时的监测时长并不能提高检出阳性率。

Abstract: Objective: To explore the diagnostic value of video electroencephalogram (EEG) of different time limits for children with epilepsy. Methods: A total of 90 children with epilepsy (from November 2022 to November 2024) in our hospital were selected for in-depth analysis. Video electroencephalogram (EEG) was completed for all of them. Video EEG analysis was performed at 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, and 24 hours of monitoring to analyze their diagnostic value. Result: Among the 90 children included in this article, the total positive rate was 82.22%. The time limit with the highest positive rate was 12 hours, followed by 3 hours, 24 hours, 6 hours, and 1 hour, and the positive rate was the lowest at 30 minutes. The electroencephalogram (EEG) features vary among different disease types. A monitoring period of up to 24 hours or longer does not increase the positive detection rate. Conclusion: In the diagnosis of pediatric epilepsy patients, among video electroencephalogram diagnoses of different time limits, a monitoring duration of more than 3 hours can significantly increase the positive rate, among which the positive rate of diagnosis is the highest at 12 hours. A monitoring duration of up to 24 hours does not increase the positive detection rate.
