目的:探讨儿童阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的诊断标准。方法:回顾性分析76例OSAHS患儿的(PSG)检查结果,分别按呼吸暂停持续时间10s和6s进行数据分析,AHI结果采用配对t检验进行统计学处理。结果:呼吸暂停持续时间为10s时,AHI为8.5342±9.6883;呼吸暂停持续时间为6s时,AHI为9.8697±10.1722,其差异有统计学意义(P<0.01)。结论:采用呼吸暂停持续时间10s与6s进行PSG结果分析,对于确立OSAHS的诊断无较大差别,但采用10s进行PSG结果判断,则低估了OSAHS患儿病情的严重程度。
Objective: To investigate the diagnostic criteria of obstructive sleep apnea-hypopnea syndrome (OSAHS) in children. Methods: A retrospective analysis of 76 children with OSAHS (PSG) test results, respectively, according to the duration of apneas 10s and 6s for data analysis, AHI results using the paired t test for statistical analysis. Results: The AHI was 8.5342 ± 9.6883 when the duration of apnea was 10s and 9.8697 ± 10.1722 with a duration of apnea of 6s, the difference was statistically significant (P <0.01). CONCLUSIONS: The use of apnea durations of 10 s and 6 s in the analysis of PSG results does not show any significant difference in the diagnosis of OSAHS. However, using 10 s for PSG results underestimates the severity of OSAHS in children.
