The Effects of Phenobarbital on Sleep Structure -Focused on the K-complex-

Polysomnographic(PSG) recordings were performed on 7 healthy male college students in the sleep laboratory of Chungnam National Unversity Hospital in order to investigate the effects of phenobarbital on the sleep structure and K-complex, After being given a night in which to adapt to the laboratory environment, PSG were recorded and the findings were regarded as a baseline for each subjects. On the next night a PSG recording was taken after the intravenous administration of lOOmg PB 20min before bedtime. Total sleep time, the percentage of each stage of sleep and the number of sptaneous K-complex which appeared in stage 2 were compared before and after the PB administration. Total sleep time and total bed time were decreased statistically significantCp^O.OS). Stage 2 sleep was increased statistically signiflcant( p<0.05). The number of K-complexs decreased after the administration, but not significantly. A significant positive correlation was observed between decreased number of K-complex and increased number of stage 2.
