睡眠监测及阻塞定位系统在睡眠相关呼吸紊乱疾病诊断中的应用

Application of ApneaGraph in the diagnosis of sleep-related breathing disorders

目的比较睡眠监测及阻塞定位系统(ApneaGragh,AG)在诊断睡眠相关呼吸紊乱疾病中的临床应用价值。方法选取40例男性患者,每位患者均使用多导睡眠检测仪(polysomnography,PSG)和AG同时监测睡眠呼吸暂停低通气指数(apnea hypopnea index,AHI)、呼吸暂停指数(apnea index,AI)、低通气指数(hy-popnea index,HI),阻塞性呼吸暂停、中枢性呼吸暂停、混合性呼吸暂停,平均血氧饱和度、最低血氧饱和度、最长呼吸暂停时间、体位等指标。结果PSG和AG所测得的AHI、AI、HI、阻塞性呼吸暂停、中枢性呼吸暂停、最长呼吸暂停时间、仰卧位及平均血氧饱和度差异均有统计学意义(P<0.01);混合性呼吸暂停、最低血氧饱和度及侧卧位差异无统计学意义(P>0.05)。PSG和AG所测得的AHI和AI高度相关(AHI:r=0.896,P<0.05;AI:r=0.699,P<0.05)。AG结果显示AHIupper%>60%者24例,余16例中AHIupper%≤10%者4例。结论AG不能完全替代PSG,但可以区别患者的阻塞位点分布情况。

Objective To observe the clinical value of ApneaGraph （AG） in the diagnosis of sleep-related breathing disorders. Methods AG and polysomnography （PSG） was performed in 40 male patients with sleep-related breathing disorders simultaneously. The apnea hypopnea index （ AHI）, hypopnea index （ HI ）, apnea index （ AI ）, obstructive apnea, central and mixed apnea, average oxygen saturation, the lowest oxygen saturation, the longest sleep apnea time and the body position was detected and the results were analyzed statistically. Results Significant differences were observed in AHI,AI, HI,obstructive apnea, central apnea, the longest sleep apnea time, supine body and average oxygen saturation between AG and PSG（ P 〈0, 05 ）. The differences in the mixed apnea, the lowest oxygen saturation, and the right or left body position between AG and PSG were not significant （P 〉 0.05）. AHI and AI was correlated both in AG and PSG （ AHI ： r = 0.896, P 〈 0.05 ; AI ： r = 0.699, P 〈 0.05）, Twenty-four in 40 patients had a AHIupper% more than 60% and 4 in the other 16 patients had a AHIupper%less than 10%. Conclusions AG could not replace PSG but could identify the obstruction position in each patient. （Chin J Ophthalmol and Otorhinolaryngo1,2010,10：79-81 ）
