目的：探讨变应性鼻炎（AR）对儿童阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的影响。方法经多导睡眠监测（PSG）明确诊断的 OSAHS 患儿91例，对其进行血清学过敏原检测。依据病史、查体及过敏原检测结果将其分成非 AR 组及 AR 组，比较两组的呼吸暂停低通气指数（AHI）及最低血氧饱和度（LSaO2）。统计学方法为两独立样本 t 检验，P ＜0．05为差异有统计学意义。结果AHI 结果 AR 组高于非 AR 组，LSaO2结果 AR 组低于非AR 组。结论变应性鼻炎可能是加重 OSAHS 严重程度的因素之一。“,”Objective To investigate the effects of allergic rhinitis (AR)on obstructive sleep apnea hypopnea syn-drome in children.Methods Ninety one children diagnosed as obstructive sleep apnea hypopnea syndrome by poly-somnography were divided into non-AR (NAR)group or AR group according to the history,physical examination and allergen testing.The apnea hypopnea index and the lowest saturation of oxygen between the two groups were compared. Results The apnea hypopnea index was higher and the lowest saturation of oxygen was lower in the AR group than those in the NAR group.Conclusion AR may aggravate obstructive sleep apnea hypopnea syndrome.
