Abstract:
Objective To explore the correlation between periodic limb movement index (PLMI) and the apnea-hypopnea index (AHI), apnea index (AI), hypopnea index (HI) and lowest oxygen saturation (LSaO_2) in sixty-four children with sleep-disordered breathing(SDB).Methods Between March 2008 and May 2009, sixty-four children suspected of OSAHS underwent overnight polysomnogram monitoring in our medicine sleep center.OSAHS was diagnosed according to the general criterion.Sixty-four children were divided into two groups.Thirty children were diagnosed as OSAHS and 34 children were diagnosed as primary snoring (PS, 32 children) or upper airway resistance syndrome (UARS, 2 children).The difference of PLMI and periodic limb movement index during sleep associated with arousals (PLMl-arousal) were compared between the two groups.Besides this, the correlation between PLMI, periodic limb movement index during sleep associated with arousals and AHI, AI, HI and LSaO_2 were also analyzed in all SDB children.Furthermore, all SDB children were divided into two groups according to PLMI (< 5 events/h vs ≥5 events/h).AHI, AI, HI, LSaO_2 and sleep structure were compared between the two groups.Results ①The difference of PLMI and PLMI-arousal between the children with OSAHS and children with other SDB types(PS and UARS) were not significant (z value, - 1.279, - 1.490; P value, 0.201,0.136, respectively).② The increased sleep stage I was significant as being compared between the two groups (<5 events/h vs ≥5 events/h, t = -2.16, P <0.05).However, other sleep stages and sleep efficiency were not significantly different (P value, all > 0.05).③ The difference of HI, AI, AHI, arousals index (ArI) and LSaO_2 were not significant between the two groups(<5 events/h vs ≥5 events/h, P value, all > 0.05).④ PLMI and PLMI-arousal were not correlated with AHI, HI, AI, AHI and LSaO_2 (Spearman rank correlation analysis).Conclusions PLMS may be independent of SDB and PLMS had a little influce on sleep structure.
