Abstract
[2] Currently, studies on microsleep architecture on electroencephalogram (EEG) arousals in SDB children have attracted more and more attention. [...]it is worth to compare the difference in EEG arousals between children with PS and children with OSAHS. Methods Patients One-hundred and nineteen children, including 100 boys and 19 girls, aged 4-13 years (mean age: 6.8 +- 2.0 years), who suspected suffering from SDB were considered as the experimental group; 30 children, including 24 boys and 6 girls, aged 4-13 years (mean age: 5.8 +- 2.9 years), with vocal nodules, who did not have sleep-related disorders were considered as the control group. According to the American Academy of Sleep Medicine (AASM) criteria, an apnea-hypopnea index (AHI) >5 or an obstructive apnea index (OAI) >1 together with an lowest arterial oxygen saturation (LSaO2) < 92% was diagnosis of OSAHS; an OAI < 1 and an LSaO2 >0.92 with total arousal index (ARtotI) < 11 was that of PS. EEG arousals were subclassified as follows: total arousal, the sum of all arousals divided by total sleep time; limb arousal, a sudden increase in EEG frequency following spontaneous limb movement in the absence of an apneic event or crescendo snoring; respiratory arousal, a sudden increase in EEG frequency within three breaths after termination of a respiratory apneic event; and spontaneous arousal, a sudden increase in EEG frequency in the absence of an obvious precipitating event. [3] observed that EEG arousals fragment sleep and affect sleep quality, causing daytime sleepiness, restlessness, inattention, poor school performance,...
