Title: Clinical analysis of the sleep structure in patients with obstructive sleep apnea syndrome
Abstract: Objective To analyze the features of sleep structure of patients with different severity of obstructive sleep apnea syndrome (OSAHS). Methods 168 adult patients with OSAHS were selected as study group, and 136 patients with simple snoring were selected as control group. All patients were monitored with polysonmography (PSG) throughout the night ,and compared the sleep structure of patients with different severity of OSAHS and simple snoring at night. Results OSAHS group compared with simple snoring group,sleep time and sleep efficiency were not significantly different(P > 0. 05);while OSAHS group had increased stage I,and decreased stage Ⅱ, SWS% and REM%, the differences were statistically significance (P < 0.05 ). The difference in severe classification group( AHI ≥40) was more significant. Conclusion OSAHS patients presented more drowsy sleep, and less deep sleep, and with the grade of OSAHS increasing,the influence of sleep structure was more obvious.
