PSQI score
±, sleep disorders, daytime dysfunction
The baseline PSQI scores did not statistically significantly differ among the three groups. Compared with the baseline, the PSQI scores of the three groups were significantly increased on the night after the operation, and the proportion of PSQI > 5 was significantly increased as well. Compared with the BC group, the PSQI scores of 1.0 Dex and 1.5 Dex groups were significantly reduced on the night after the operation (BC, 1.0 Dex, 1.5 Dex:7.8 ± 3.6, 4.9 ± 2.8, 4.1 ± 2.0), and the proportion of PSQI > 5 was also significantly reduced (BC, 1.0 Dex, 1.5 Dex:71.8, 25.6, 25.6%). However, there was no statistically significant difference between 1.0 Dex and 1.5 Dex groups (Comparison of PSQI scores of three groups.
There is a statistical difference compared with the BC group.There is a statistical difference compared with the 1.0 Dex group.Comparison of PSQI scores among the three groups.The baseline scores of the aforementioned A-F items did not significantly differ. Regarding scores for sleep quality (item A), sleep duration (item C), and sleep efficiency (item D), the postoperative scores of the three groups were significantly increased compared with the baseline score. Postoperative scores of items A, C, and D decreased significantly in the 1.5 Dex group, but there was no statistical difference between the 1.0 Dex group and the 1.5 Dex group. Regarding the sleep latency score (item B), the postoperative sleep latency scores of the BC group and the 1.0 Dex group were significantly increased compared with the baseline score, and the 1.5 Dex group had the least score. Regarding the scores for sleep disorders (E) and use of sleep medication (F), the scores on the night after operation in all three groups were significantly increased compared with the baseline score; however, there was no statistically significant difference in these scores among the three groups. Regarding the score for daytime dysfunction (item G), the 1.5 Dex group had a lower baseline score than the BC group. The scores of the BC group and the 1.0 Dex group were decreased and that of the 1.5 Dex group was increased compared with the baseline score; however, the scores of the three groups did not statistically significantly differ on the night after operation (
