Abstract：Objective To explore the changes of sleep structure in 102 children of obstructive sleep apnea hypopnea syndrome (OSAHS).Methods All 102 cases with adenoid and tonsils hypertrophy undertook monitoring nocturnal sleep and breathing by Alice-5 monitor of sleep were selected.The apnea hypopnea index(AHI),obstruct apnea index(OAI),lowest oxygen saturation(LSaO2),arousal index,the length of sleep stage Ⅰ,Ⅱ,Ⅲ,Ⅳ,and slow wave sleep(SWS)length,rapid eye movement(REM)length were detected and analyzed.Results The patients with OSAHS accompanied by adenoidal and tonsils hypertrophy showed airway obstruction.The AHI was significantly related to arousal index,S1,SWS and LSaO2 (R =0.37,0.26,-0.22,-0.41,respectively)(all P ＜ 0.05).The OAI was significantly related to arousal index and LSaO2 (R =0.29,- 0.26)(all P ＜ 0.05).Conclusions The block in growth of children with OSAHS and development of their brain is derived from the less of the oxygen concentration,and not just because of the decrease of REM period.The correction of low oxygen concentration,improvement of the sleep quality should be achieved for the recovery of children with OSAHS.
