【摘要】：多导睡眠图(PSG)是一种监测睡眠和醒觉机体多种生理活动的技术,是诊断睡眠呼吸暂停综合征(SAS)的标准手段。本院已进行PSG监测3 000余例,本文结合本院2012年1—10月随机选取的22例患者PSG监测结果,对PSG实际操作及分析中的若干问题进行探讨。PSG监测前患者需充分准备,传感器应正确安置;用脑电电极Fp1A2、Fp2A1替代C3A2、C4A1进行睡眠结构的分析,对睡眠各期的睡眠结构无影响(P0.05)。另外,PSG监测结果应进行人工校正,因为人工校正前后清醒期、Ⅰ期睡眠、深睡眠、快速动眼期的睡眠结构间有差异(P0.05);人工校正后呼吸暂停低通气指数(AHI)、最长呼吸暂停时间、最长低通气时间与校正前比较亦有差异(P0.05),但血氧饱和度间无差异(P0.05)。总之,一份良好的睡眠记录及各项指标的正确分析可获得准确的PSG监测结果。
[Abstract]:Polysomnography (PSG) is a technique for monitoring sleep and waking up to a variety of physiological activities, and is a standard method for diagnosis of sleep apnea syndrome (SAS). More than 3 000 cases of PSG monitoring have been carried out in our hospital. According to the results of PSG monitoring in 22 patients randomly selected from January to October 2012, some problems in practical operation and analysis of PSG should be fully prepared. The sensor should be placed correctly, and the sleep structure should be analyzed by replacing C3A2C4A1 with Fp1A2Fp2A1, which had no effect on the sleep structure of each stage of sleep. In addition, the monitoring results of PSG should be corrected manually, because there are differences in sleep structure between awake period, stage I sleep, deep sleep and rapid eye movement period before and after artificial correction; after manual correction, the apnea hypopnea index (AHI) is the longest apnea time. The maximum time of hypopnea was also different from that before correction (P 0.05), but there was no difference in blood oxygen saturation (P 0.05). In a word, a good sleep record and correct analysis of each index can obtain accurate PSG monitoring results.
