混合性睡眠呼吸暂停综合征多导睡眠图分析

摘要

目的：探讨混合性睡眠呼吸暂停综合征多导睡眠图特征及其诊断标准。方法：对22例睡眠呼吸暂停综合征住院患者，根据多导睡眠图描记，分为混合性睡眠呼吸暂停综合征与阻塞型呼吸暂停综合征两组，结合其临床资料统计分析。结果：两组多导睡眠检测分析，总睡眠时间、REM期时间、睡后总觉醒时间、觉醒次数、呼吸暂停低通气指数等呼吸睡眠参数无统计学意义（P＞0．05）；MSAS次数与呼吸暂停总次数之比大于50％共10例，介于50％～70％者6例，70％～90％者4例。结论：MSAS与OSAS多导睡眠图相关指标无统计学差异，MSAS诊断以PSG检测混合性暂停次数占呼吸暂停总次数50％以上为依据是较正确的方法。%Objective:To analyze the features of polysomnography(PSG) in patients with mixed sleep apnea syndrome(MSAS) to define the diagnostic criteria for this entity.Methods:Twenty-two inpatients with complex sleep apnea syndrome were divided into two groups as MSAS or obstructive sleep apne-a syndrome ( OSAS) in compliance with PSG results,and the clinical data were summarized and statistically analyzed .Results:PSG results indicated no significance in the two groups of patients regarding the total sleep time,time in REM,total number of awakening time and frequencies of awakening after sleep,as well as apnea-hypopnea index(P>0.05).In MSAS group,the ratio of MSAS episodes to total quantity of breathing pause over 50% occurred in 10 cases,between 50% and 70% in 6,and 70%-90% in 4.Conclusion:PSG indicates no significant change between patients with MSAS and OSAS, suggesting that final diagnosis of MSAS should rely on the quantity of apneic events over 50%.
