이정규,왕성근 大韓神經精神醫學會 1993 신경정신의학 Vol.32 No.6

Polysomnographic(PSG) recordings were performed on 7 healthy male college students in the sleep laboratory of Chungnam National University 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 100mg 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 wee compared before and after the PB administration. Total sleep time and total bed time were decreased statistically significant(p<0.05). Stage 2 sleep was increased statistically significant(p<0.05). The number of K-complex 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.

To identify the effects of partial sleep deprivation on the sleep structure, the authors performed polysomnographic study for 9 healthy young adults. The subjects were college students, ranging in age from 20 to 25 years, without personal past or present histories of medical, neurological, or psychiatric illness and suffering from current sleep disturbance or parasomomnias. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales' manual and tried paired t-test. The results were summarized as follows. 1. As for sleep parameters, total sleep time(TST), REM latency and REM duration were not changed significantly during deprivation period and recovery period compared with baseline. Sleep efficiency increased significantly during deprivation period and recovery period compaired with baseline, and sleep latency and WASO were shortened significantly during deprivation period and recovery period compared with baseline. 2. As for sleep structure, 1) The absolute value(minutes) of stage 1 decreased significantly during deprivation period and first recovery night compared with baseline, and the relative value(percentage) of stage 1 decreased significantly during deprivation period and recovery period compared with baseline. 2) The absolute value(minutes) of stage 2 decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of stage 2 decreased significantly during deprivation period and first recovery night compared with baseline. 3) The absolute value(minutes) of slow wave sleep were not changed significantly during deprivation period and recovery period compared with baseline, and the relative value(percentage) of slow wave sleep increased significantly during recovery period compared with baseline. 4) The absolute value(minutes) of REM sleep decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of REM sleep decreased significantly in the first deprivation night but, were not changed significantly during recovery period compared with baseline.

Correlations among sleep parameters diagnosed as obstructive type SAS, WASO was negative correlation with total sleep time, non-REM sleep time was positive correlation with total sleep time and negative correlation with WASO. Sleep efficiencies was positive correlation with total sleep time and non-REM sleep time, and negative correlation with WASO. And, slow wave sleep time was negative correlation with stage 1 sleep time and stage 2 sleep time. Above results were thought to be as useful data in clinical practice for the explanation of characteristics of korean sleep apnea syndrome.
