目的：探谈不同程度阻塞性睡眠呼吸暂停低通气综合征（obstructive sleep apnea hypopnea hyndrome， OSAHS）患者夜间不同睡眠体位下呼吸暂停低通气指数（apnea hypopnea index，AHI）和血氧饱和度下降指数（oxygen desaturation index，ODI）的差异及变化特点。方法回顾性分析经多导睡眠图（polysomnography，PSG）监测确诊的OSAHS患者及部分正常体检患者113例，对各组中不同体位的AHI及ODI值进行统计学分析。结果正常组：AHI、ODI值仰卧位时明显高于左、右侧卧位；轻中度组：OSAHS组中AHI、ODI值仰卧位略高于左侧卧位，仰卧位明显高于右侧卧位；重度组：仰卧位与左侧卧位相比差异无统计学意义，仰卧位与右侧卧位相比差异明显。结论不同程度OSAHS患者夜间睡眠中仰卧位时AHI及ODI均高于侧卧位；在侧卧位中，右侧卧位比左侧卧位更能降低呼吸暂停或低通气次数以及血氧饱和度下降次数发生的优势。并且，ODI对反映OSAHS患者病情严重程度与AHI表现出一致性。

[ABSTRACT]OBJECTIVETo assess the sleep body position's effects on AHI and ODI during sleep in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different severity.METHODSThe clinical data of 113 subjects who had been diagnosed OSAHS or normal by polysomnography (PSG) between 2013 and 2014 in our department were retrospectively studied. They were divided into normal control group (AHI<5/h, 41 patients), mild to moderate OSAHS group (5/h<AHI≤30/h, 32 patients) and severe group (AHI>30/h, 40 patients). PSG data of AHI and ODI in different body position in each group were further analyzed.RESULTSIn normal group, The AHI and ODI in supine position were significantly higher than that in the left or right lateral position, and the difference between the left and right lateral position was not significant. In the mild to moderate OSAHS group, the AHI and ODI in supine were higher than that in the left lateral position slightly, while the data in supine was higher than that in the right lateral position significantly. In the severe group, the data between the supine and the left lateral position was not statistically different, while the supine position data was higher compared with that of the right lateral position. CONCLUSIONAHI and ODI were higher in supine position than that in lateral position, while the AHI and ODI in right lateral position is higher than that in left lateral position in OSAHS patients with different severity. The ODI and AHI are consistent in reflecting the severity of the OSAHS.
