Abstract

Objectives: To discribe some of the signs and symptoms of sleep disorders by PSQI scale and characteristics of polysomnographic parameters in sleep disorder patients who come to the hospital for examination and treatment at Ha Ha Medical University Hospital in 2020-2021. Methods: Cross-sectional description on 30 patients who came to the clinic and recorded polysomnography at Hanoi Medical University Hospital from July 2020 to May 2021. Results and conclusion: All patients had a decrease in sleep quality according to the PSQI scale with a total mean score of 18.0 ± 6.0 points. In which, over 90% of patients woke up in the middle of the night, coughed or snored loudly while sleeping, had difficulty to stay awake during the day and sleeped less than 7 hours. 30% of patients had more than 85% sleep efficiency. All patients had at least one sleep disorder. The duration of sleep was less than 5 hours and there was apnea-hypopnea, accounting for more than 50%. The average sleep duration was 5.4 ± 1.1 hours, of which 29/30 patients slept less than 7 hours. The average SE was 79.6 ± 15.1%, over 70% had SE from 80% and more. Mean AHI: 34,0 ± 28,9 times/hour. 86,7% had sleep apnea and 50% of all patients had severe apnea. Median time to fall asleep: 8 minutes (0 - 125.5 minutes). The sleep structure has changed compared to normal, the N1 phase lengthens and shortens the others sleep stages. 96.7% of study subjects had sleep fragmentation, the average rate of waking time after starting to sleep was 19.0 ± 15.5%, the number of waking times during the night was 23.2 ± 15.3 times, and the average AI was 34.1 ± 19.1 times/hour. 16.7% of subjects had cyclic leg movement detected on polygraph without clinical symptoms.
