Daytime-sleepiness is the main symptom of the obstructive sleep apnoea syndrome. Standarized questionnaires (e.g. the Epworth sleepiness scale = ESS) have become useful diagnostic tools. In this study we investigated wether there is a difference between the estimation of initial "pre-treatment" daytime sleepiness (by ESS) compared to the retrospective ESS score after implementation of CPAP therapy.
We included 46 patients (RDI 39/h +/- 20.2, CPAP pressure 8 cm/H2O +/- 1.7, daily use of 5.8 h +/- 1.8, RDI with CPAP 7.6/h +/- 5.3). We examined the ESS score before CPAP-therapy (ESS-base) in comparison to the retrospective estimation of the initial conditions after one year of CPAP-therapy (ESS-retro).
There was no statistical significant difference between ESS base (11.7 +/- 4.6) and ESS-retro (12.7 +/- 5.2). ESS decreased to 5.4 +/- 3.7 by CPAP-therapy (p < 0.01).
From a chronological point of view ESS is a consistent parameter of daytime sleepiness. Hence, the retrospective estimation of pre-CPAP ESS can be considered as a useful diagnostic tool.
日间嗜睡是阻塞性睡眠呼吸暂停综合征的主要症状。标准化问卷（如Epworth嗜睡量表=ESS）已成为有用的诊断工具。在本研究中，我们调查了与持续气道正压通气（CPAP）治疗实施后的回顾性ESS评分相比，初始“治疗前”日间嗜睡估计值（通过ESS）之间是否存在差异。
我们纳入了46例患者（呼吸紊乱指数39次/小时±20.2，CPAP压力8厘米水柱±1.7，每日使用时间5.8小时±1.8，CPAP治疗下呼吸紊乱指数7.6次/小时±5.3）。我们比较了CPAP治疗前的ESS评分（ESS基础值）与CPAP治疗一年后对初始状况的回顾性估计值（ESS回顾值）。
ESS基础值（11.7±4.6）与ESS回顾值（12.7±5.2）之间无统计学显著差异。通过CPAP治疗，ESS降至5.4±3.7（p<0.01）。
从时间顺序的角度来看，ESS是日间嗜睡的一个一致参数。因此，CPAP治疗前ESS的回顾性估计可被视为一种有用的诊断工具。
