The objective of this study is to compare the use of Multiple Sleep Latency Test (MSLT) and Epworth Sleepiness Scale (ESS) in measuring excessive daytime sleepiness (EDS) in patients with different severity of obstructive sleep apnoea syndrome (OSAS).
Two hundred ninety-six consecutive OSAS patients, with their EDS measured by a Chinese version of ESS and a five-nap MSLT, and their severity of OSAS (determined by respiratory disturbance index) by a nocturnal polysomnogram, were classified into mild (RDI 5-15/h, n=59), moderate (RDI 15-30/h, n=71) and severe (RDI >30/h, n=166) groups, respectively. Their ESS, MSLT and other sleep parameters were compared.
The severe group had significantly shorter mean sleep latency (MSL=6.26+/-4.90 min) than the moderate (8.26+/-4.57 min) and mild groups had (8.07+/-4.37 min). There was no significant difference in their ESS scores.
MSLT is better than ESS in the measurement of EDS in relation to the severity of OSAS in clinical patients.
本研究旨在比较多次睡眠潜伏期试验(MSLT)和爱泼沃斯思睡量表(ESS)在测量不同严重程度阻塞性睡眠呼吸暂停综合征(OSAS)患者日间过度嗜睡(EDS)方面的应用。
296例连续的OSAS患者,采用中文版ESS和五小睡MSLT测量其EDS,通过夜间多导睡眠图测定其OSAS严重程度(由呼吸紊乱指数确定),分别分为轻度组(呼吸紊乱指数5 - 15次/小时,n = 59)、中度组(呼吸紊乱指数15 - 30次/小时,n = 71)和重度组(呼吸紊乱指数> 30次/小时,n = 166)。比较他们的ESS、MSLT及其他睡眠参数。
重度组的平均睡眠潜伏期(MSL = 6.26 ± 4.90分钟)显著短于中度组(8.26 ± 4.57分钟)和轻度组(8.07 ± 4.37分钟)。他们的ESS评分无显著差异。
在临床患者中,就OSAS严重程度而言,MSLT在测量EDS方面优于ESS。
