Sleep movement disorders includes mainly periodic limb movement and others. The more frequent breathing disorders are: obstructive sleep apnea-hypopnea syndrome and primary snoring.
To compare sleep architecture in periodic limb movements and breathing disorders of different severity, and weight their interactions.
We compared sleep architecture in 160 patients, divided in six groups: periodic limb movements (n=25), obstructive apnea only (n=30), periodic limb movements/snoring (n=30), periodic limb movements/mild apnea (n=25), periodic limb movements/moderate apnea (n=25), periodic limb movements/severe apnea (n=26). Polysomnographic variables were compared by analysis of variance and Tukey test.
We observed an increase of percentage of awakenings in the group with periodic limb movements/severe apnea. We found an increase of percentage of light sleep in the group with obstructive apnea only with respect to periodic limb movements group. The group with obstructive apnea only presented less rapid eye movements sleep in relation with group with periodic limb movements. We found an increase of awakenings in the group with periodic limb movements/severe apnea to the group with periodic limb movements only. Oxygen saturation showed a decrease in the group with periodic limb movements/severe apnea and obstructive apnea only group to periodic limb movements only group.
Periodic limb movements and breathing disorders, resulted in more additive changes in sleep architecture alterations, than as separately disorders, in a complex interaction. Research in these relations deserve more investigations.
睡眠运动障碍主要包括周期性肢体运动及其他。较常见的呼吸障碍有:阻塞性睡眠呼吸暂停低通气综合征和原发性打鼾。
比较不同严重程度的周期性肢体运动和呼吸障碍患者的睡眠结构,并权衡它们之间的相互作用。
我们比较了160例患者的睡眠结构,这些患者分为六组:周期性肢体运动组(n = 25)、单纯阻塞性呼吸暂停组(n = 30)、周期性肢体运动/打鼾组(n = 30)、周期性肢体运动/轻度呼吸暂停组(n = 25)、周期性肢体运动/中度呼吸暂停组(n = 25)、周期性肢体运动/重度呼吸暂停组(n = 26)。通过方差分析和Tukey检验比较多导睡眠图变量。
我们观察到周期性肢体运动/重度呼吸暂停组的觉醒百分比增加。我们发现,单纯阻塞性呼吸暂停组的浅睡眠百分比相对于周期性肢体运动组有所增加。单纯阻塞性呼吸暂停组的快速眼动睡眠比周期性肢体运动组少。我们发现,从周期性肢体运动/重度呼吸暂停组到仅周期性肢体运动组,觉醒次数增加。氧饱和度在周期性肢体运动/重度呼吸暂停组和单纯阻塞性呼吸暂停组相对于仅周期性肢体运动组有所下降。
在复杂的相互作用中,周期性肢体运动和呼吸障碍导致的睡眠结构改变比单独的障碍更具累加性变化。对这些关系的研究值得更多的调查。
