Table 2 Surgical parameters and postoperative recovery indicators, mean ± SD

Parameters	Control group (n = 106)	Esketamine group (n = 112)	P value2
Operative duration (minute)	186.4 ± 42.8	182.6 ± 38.4	0.476
Intraoperative blood loss (mL)	168.4 ± 86.2	162.8 ± 82.6	0.618
Extubation time (minute)	18.6 ± 6.4	14.2 ± 5.8	< 0.001
Intensive care unit stay duration (hour)	28.4 ± 12.6	22.8 ± 10.2	0.001
Hospital length of stay (day)	8.6 ± 2.4	7.8 ± 2.2	0.012
Chest tube drainage duration (day)	4.8 ± 1.6	4.4 ± 1.4	0.065
Total opioid consumption (mg)1	86.4 ± 24.2	64.8 ± 18.6	< 0.001

¹Total opioid consumption expressed as oral morphine equivalents in milligrams, calculated using standard equianalgesic conversion ratios for all administered opioids including intravenous fentanyl, sufentanil, and oral oxycodone.

²P values were calculated using independent samples t-test.
