体位对轻度阻塞性睡眠呼吸暂停患者睡眠结构的影响

Influence of Position on Sleep Structure of Patients with Mild Obstructive Sleep Apnea

目的:比较非体位性与体位性阻塞性睡眠呼吸暂停(Obstructive Sleep Apnea,OSA)患者的睡眠结构,探讨睡眠体位对轻度OSA患者睡眠结构的影响。方法:选取2018年1月至2020年12月在北京大学国际医院睡眠中心行标准夜间多导睡眠监测(Nocturnal Polysomnography,nPSG)并确诊为轻度OSA患者133例作为研究对象。根据PSG中不同体位下AHI的大小将其分为2组:体位组(仰卧位AHI≥2×非仰卧位AHI)和非体位组(仰卧位AHI<2×非仰卧位AHI)。结果:非体位组和体位组的就诊年龄、BMI和AHI比较差异均无统计学意义(P>0.05)。就诊年龄、BMI和AHI均不是体位性OSA的独立预测因子。体位组睡眠效率比非体位组的高;体位组入睡后清醒时间比非体位组的短,差异有统计学意义(均P<0.05)。结论:OSA的病情严重程度与体位密切相关,改变体位可以改善轻度OSA患者的睡眠质量。

Objective:To compare the sleep structure of patients with non-positional and positional OSA,and investigate the effect of sleep position on the sleep structure of patients with mild OSA.Methods:From January 2018 to December 2020,133 patients diagnosed with mild OSA were examined with standard Nocturnal polysomnography(Nocturnal Polysomnography,nPSG)in Sleep Center of Peking University International Hospital.According to the size of AHI in different position in PSG,they were divided into two groups:positional group(supine AHI≥2×non-supine AHI)and non-positional group(supine AHI<2×non-supine AHI).Results:There was no significant difference in age,BMI and AHI between the non-positional group and the positional group(P>0.05).Age at diagnosis,BMI and AHI are not independent predictors of positional OSA.The sleep efficiency of the positional group was higher than that of non-positional group;the wake after sleep onset in the positional group was shorter than that of non-positional group(all P<0.05).Conclusion:The severity of OSA is closely related to position.Changing the position can improve the sleep quality of patients with mild OSA.
