微动敏感床垫式睡眠监测仪在儿童OSAHS诊断中的应用

The application of micro-sensitive mattress type sleep monitor in the diagnosis of OSAHS in children

目的:探讨儿童型微动敏感床垫式睡眠监测仪(简称床垫系统)对儿童OSAHS的睡眠监测效果。方法:同步行经PSG监测及床垫系统监测诊断为OSAHS的儿童58例,对两种方法获得的呼吸和睡眠指标进行比较,了解床垫系统监测的可靠性。结果:58例中,经PSG监测,轻度41例,中度14例,重度3例;床垫系统监测结果为轻度37例,中度16例,重度5例。其中7例患儿经PSG监测诊断为轻度,床垫系统监测结果为中度;床垫系统监测结果为轻度的3例患儿经PSG诊断结果为中度。14例经PSG诊断为中度的患儿,床垫系统将其中的3例诊断为轻度,2例诊断为重度。PSG诊断为重度的患儿床垫系统均诊断为重度。两种睡眠监测方法的结果进行比较,其中AHI(t=2.316,P>0.05),深、浅睡眠构成比差异无统计学意义(t=2.280,t=2.388,均P>0.05);REM期睡眠构成比差异有统计学意义(t=3.135,P<0.01)。结论:儿童型微动敏感床垫对儿童OSAHS的诊断与PSG有较好的一致性,可以作为一种监测方法应用于临床工作。

Objective：To investigate the result of child-type micro-sensitive mattress sleep monitor on obstruc- tive sleep apnea-hypopnea syndrome in children. Method： The PSG and child type micro-sensitive mattress sleep monitor were synchronously performed on 58 cases of children with OSAHS. The breathing and sleep metrics were compared. Result： By PSG monitoring, 41 cases were diagnosed as mild OSAHS, 14 cases were moderate and 3 cases were severe. The results of mattress system monitoring showed mild OSAHS in 37 cases, 16 cases of moderate and severe OSAHS in 5 cases. Seven patients diagnosed as mild OSAHS monitored by PSG were classi- fied as moderate by mattress system monitoring; three cases diagnosed as mild OSAHS by mattress system moni- toring system were diagnosed as moderate by PSG. Among 14 cases of children diagnosed as moderate by PSG, three cases were diagnosed as mild by mattress system monitor and two cases as severe. Children diagnosed as se- vere by PSG got the same result by mattress system monitor. Two kinds of sleep monitoring methods were corn pared and there were no statistically significant difference in AHI（t=2. 316, P〈0.05）, deep and shallow sleep constituent ratio （t=2. 280, t=2. 388, P〈 0.05）, while there was significant difference in REM period Sleep constituent ratio （t= 3. 135, P〈0.01）. Conclusion： Child-type micro-sensitive mattress is in good agreement with the PSG for diagnosing OSAHS in children, which can be used as a monitoring method in clinical work.
