title: [The effect of CPAP treatment on excessive daytime somnolence in patients with obstructive sleep apnea].
abstract: The study was undertaken to investigate whether a CPAP therapy improves symptoms of excessive daytime sleepiness (EDS) in patients with obstructive sleep apnoea (OSA). In seventy six patients (66 M and 10 F) with AHI = 50 +/- 3.3, BMI = 34 +/- 0.9 kg/m2 and mean age = 50.4 +/- 1 years OSA was diagnosed using standard polysomnography. EDS was assessed using Epworth Sleepiness Scale (ESS). Each patient was examined two or three times, before, after 1 and/or 2-15 months of CPAP treatment. Significant reduction of EDS within 1 month of CPAP therapy was found. Mean ESS was reduced from 14.3 +/- 0.9 to 7.0 +/- 0.7 after 1 month therapy (p < 0.001). Continuation of treatment had no further effect on decrease of symptoms of daytime sleepiness. There was a correlation between percent of sleep spent with CPAP and improvement in ESS.
