阻塞性睡眠呼吸暂停低通气综合征两种初筛诊断方法的比较

Comparison of two preliminary screening methods for obstructive sleep apnea hypoventilation syndrome

利用睡眠呼吸暂停综合征量表（SA—SDQ）、睡眠评价量表（ESS）对25例鼾症和120例阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者进行问卷调查，分别计算SA-SDQ评分和嗜睡评分（EP）。然后将患者的多导睡眠仪（PSG）检查结果与评分和患者相关资料进行统计学分析。结果显示，鼾症与各组OSAHS患者之间SA—SDQ评分、EP评分、夜间睡眠呼吸紊乱指数、夜间最低氧饱和度差异有统计学意义，EP与睡眠呼吸紊乱指数呈明显正相关（r=0．78，P〈0．01），SA—SDQ评分与睡眠呼吸紊乱指数亦呈正相关（r=0．66，P〈0．01），即病情越重，EP、SA—SDQ评分越高。即睡眠评价量表可以用于临床OSAHS的初筛，SA—SDQ评分的诊断符合率低，诊断价值有限。

Both the sleep apnea scale of sleep disorders questionnaire （SA-SDQ） and the Epworth sleepiness scale （ESS） were used to evaluate 25 patients with snoring and 125 patients with obstructive sleep apnea hypoventilation syndrome （OSAHS）, and scores were calculated and compared to the results of polysomnography （PSG）. Results showed that there was significant difference in scores of ESS and SA-SDQ, apnea hyponea index （AHI） and the minimal saturation of blood oxygen （LSpO2 ） at night between patients with OSAHS and those with snoring （ P 〈 0. 05 ）. Score of both ESS and SA-SDQ significantly correlated with AHI （r =0. 78 and r = 0. 66, respectively, P 〈 0. 01 ） , i.e. , more severe of the condition, higher the scores. Score of ESS is highly consistent with clinical presentations in patients with OSAHS and can be used as preliminary screening for its diagnosis, however, use of SA-SDQ score is limited in diagnosing OSAHS due to its lower consistency.
