Abstract

|
Study objectives : The purpose of this study was to evaluate the effect of sleep deprivation cr, daytime sleepiness, fatigue, and attention measured by Vienna Test System and VAS.
Participants : 9 healthy, normal young male college students participated in this sl:udy. Participating subjects were in good physical and psychological health and were asymtomatic as to sleep/wake complaints
Intvervention : Subjects visited our laboratory by 08:00 at the first day, and they had baseline Vienna Test(at 9 00, 11 ~ 00, 14 ~ 00, and 16 ~ 00). Each time, the subjects completed VAS for sleepiness and fatigue before they underwent an Vienna Test to evaluate their attention and vigilance. They had 4 hours of sleep at 1st day, 2 hours at 2nd days, and total sleep deprivation at 3rd day and repeated the same process as those of the first day.
Result : As compared to baseline, subjects had significantly increased daytime sleepiness and fatigue and de-creased vigilance, but no significant difference in attention. The more sleep deprivation duration increased, the more daytime sleepiness and fatigue increased.
Conclusion ~ Additional study is needed to get objective data for daytime sleepiness and fatigue and to correlate among daytime sleepiness, fatigue, attention and vigilance.
