Table 2 Primary outcome, minimum ΔP after PEEP titration and individualized PEEP

Variables	TEA group (n = 30)	Control group (n = 30)	P value
Primary outcome
Minimum ΔP (cmH₂O)	11.23 ± 2.19	12.67 ± 2.70	0.028
Method of Surgery
Minimum ΔP for laparoscopic surgeries (cmH₂O)	11.95 ± 1.91	13.57 ± 2.44	0.023
Minimum ΔP for laparotomy surgeries (cmH₂O)	9.80 ± 2.10	10.56 ± 2.07	0.439
Individualized PEEP	9.00[8.00–10.00]	9.00[8.00–10.00]	0.844
Method of Surgery Individualized PEEP for laparoscopic surgeries (cmH₂O)	9.50[9.00–10.00]	10.00[9.00-10.50]	0.512
Individualized PEEP for laparotomy surgeries (cmH₂O)	7.50[6.75-8.00]	7.00[7.00-8.50]	0.497

Data are expressed as mean ± standard deviation. TEA, thoracic epidural anesthesia; ΔP, driving pressure; PEEP, positive end-expiratory pressure
