The Sleep Architecture Of The OSAHS Children And PS Children

Objective： Retrospective analyses the sleeparchitecture’s feature in the children with obstructive sleep apneahypopnea syndrome and the children with the primary snoring and toexplore if there exists some difference between the two groups andcompared with the normal children, to observe the changes of sleeparchitecture of the two groups(OSAHS group and PS group).Methods：We selected84children from the sleep center of SiChuan West Chinahospital:57cases are male,27cases are female. the average ages（7.27±1.16）岁，mean weight（29.26±10.88）kg，mean BMI（17.90±5.34）kg/m2, aged from6～9years old, with snoring, mouth breathing, dyspneaor even apnea, during the night sleep and absent-mind in the daytimewere selected as the objects of the study and were divided into twogroups——the OSAHS group and PS group. They all were monitoredby the Alice5nocturnal polysomnography and the results were comparedand analysed between the two groups. Then the two groups werecompared with the normal group. Correlation Analysis: the Ⅲ+Ⅳ%，MI，REM%of the two groups were compared with the AHI.Results：The results compared between PS group and OSAHS group: sleep latency（16.61±26.47vs15.66±19.11min）, Sleep efficiency（87.15%±7.30%vs87.11%±10.85%）,stageⅠ%（14.70%±11.49%vs18.31% ±10.73%）、stageⅡ%（40.72%±16.48%vs39.55%±15.17%）stageⅢ+Ⅳ%（SWS stage）（34.90%±15.22%vs30.33%±12.52%）、REM%（9.69%±5.14%vs11.83%±7.24%） were not statisticallysignificant （P＞0.05）. But the micro-arousal index(MI)（7.49±3.09vs14.76±9.70once/h）、Min SaO2（88.12%±7.79%vs79.41%±14.24%） were statistically significant（P＜0.01）. The two groupsrespectively compared with the normal children(6～9years old)in China:the various elements of the sleep structure between the two groups(PSgroup and OSAHS group) and the normal group were statisticallysignificant（P＜0.05）.Which shows: stageⅠ%and stageⅢ+Ⅳ%increased，stageⅡ%and REM%decreased. Correlation Analysis: onlythe AHI and MI of the OSAHS group have significant correlation, thePearson related coefficient is0.524,P=0.000(P＜0.01)，the others didn’thave significant correlation(P＞0.05). Conclusion：The sleep architecturebetween the PS group and the OSAHS group is similar. The sleepstructure of the two groups has changed: stageⅠ%and stageⅢ+Ⅳ%increased，stageⅡ%and REM%decreased. We conclude:the OSAHSand PS could effect the sleep structure of the children. According to theresults of the correlation analysis, the OSAHS children have higher AHIand higher MI,which seems more arousal during sleep than the PSchildren.
