Compared with the BC group, the 1.0 Dex group and the 1.5 Dex group had prolonged N2 sleep (BC, 1.0 Dex, 1.5 Dex: 181.4 ± 72.2, 240.7 ± 89.4, 259.4 ± 71.5 min), shorter wake-up time (BC, 1.0 Dex, 1.5 Dex: 187.9 ± 101.0, 91.4 ± 67.0, 97.4 ± 75.3 min), fewer awakenings from sleep (BC, 1.0 Dex, 1.5 Dex: 31.1 ± 15.8, 19.8 ± 10.7, 17.6 ± 11.0 times), and significantly improved sleep efficiency (BC, 1.0 Dex, 1.5 Dex: 67.1 ± 17.7, 84.0 ± 11.8, 82.7 ± 13.0%). However, these aspects did not significantly differ between 1.0 Dex and 1.5 Dex groups. Compared with the BC group and the 1.0 Dex group, the 1.5 Dex group was associated with significantly prolonged N3 sleep (BC, 1.0 Dex, 1.5 Dex: 42.8 ± 38.4, 53.6 ± 74.7, 75.0 ± 65.7 min). The three groups did not statistically significantly differ in terms of N1 sleep and REM sleep stages, average HR during sleep, highest HR during sleep, and lowest blood oxygen saturation during sleep (Comparison of sleep rhythms in the three groups of participants on the night after operation (
