摘　　要：目的 探索体位性阻塞性睡眠呼吸暂停(positional obstructive sleep apnea, POSA)患者和非体位性阻塞性睡眠呼吸暂停(non-positional obstructive sleep apnea, NPOSA)患者的临床特点以及觉醒阈值差异。方法 收集因打鼾完善睡眠呼吸监测的患者,分析患者的临床数据、睡眠数据,计算低觉醒阈值情况。对POSA组和NPOSA组的数据进行比较。结果 在纳入的322例患者中,POSA患者占比为48.8%。POSA组的体质量指数(body mass index, BMI)呼吸暂停低通气指数(apnea-hypopnea index, AHI)和CT90占比显著低于NPOSA组(26.3 vs. 27.2,P=0.02;23.2 vs. 56.2,P<0.001;1.8 vs. 4.9,P=0.044),最低及平均血氧饱和度显著高于NPOSA组(82.0 vs. 79.0,P=0.038;95.0 vs. 94.1,P=0.019)。此外,POSA组中低觉醒阈值患者占比显著高于NPOSA组(29.3%vs. 8.5%,P<0.001)。结论 POSA患者的BMI和AHI低于NPOSA患者。低觉醒阈值可能在POSA的发生发展中起一定作用。Objective To evaluate the clinical features and arousal threshold of patients with positional and non-positional obstructive sleep apnea.Methods All patients who underwent polysomnography(PSG)were enrolled,their demographic and polysomnographic data were collected,and arousal thresholds were calculated.These data were compared between the positional obstructive sleep apnea(POSA)and non-positional obstructive sleep apnea(NPOSA)groups.Results Among all the 322 patients with OSA,the prevalence of POSA was 48.8%.Patients with POSA had lower BMI,AHI and CT90(26.3 vs.27.2,P=0.02;23.2 vs.56.2,P<0.001;1.8 vs.4.9,P=0.044),as well as higher lowest and average oxygen saturation(82.0 vs.79.0,P=0.038;95.0 vs.94.1,P=0.019)compared to patients with NPOSA.Furthermore,a higher percentage of patients with POSA had a low arousal threshold compared to patients with NPOSA(29.3%vs.8.5%,P<0.001).Conclusion POSA was associated with lower BMI and AHI.Low arousal threshold may play a role in the development of positional OSA.
