Abstract:
Objective Spike and wave index (SWI) is of great importance for the diagnosis of electrical status epilepticus during sleep (ESES) in children patients. This study intended to compare four commonly used SWI methods with full night SWI to evaluate their performances. Methods Fifteen patients diagnosed with ESES by electroencephalogram initial report (SWI≥50%) were retrospectively analyzed,and SWI was calculated for the full night sleep(SWI),the first sleep cycle (SWI1),the first 5 minutes of the first sleep cycle (SWI15 min),the first 10 minutes (SWI10 min) and the first 15 minutes (SWI15 min). Wilcox paired test was used to compare SWI with other four SWI methods respectively. Results The SWI of all four methods was significantly different from the full night SWI (p-values of 0.003、0.002、0.002和0.001,respectively,α=0.0125). Among the 15 patients,14 (93.3%) had the trend that SWI decreased with sleep cycles overnight. Conclusion None of the four methods of SWI is a good substitute for full night SWI. The SWI tends to decrease with sleep cycles overnight,and using the first sleep cycle or anepoch of it to calculate SWI is likely to be overestimated.
