Perioperative characteristics in both groups.

Variables	Group VCV (n=25)	Group PCV-VG (n=25)	P value
Procedures duration (h)	1.97±0.25	2.06±0.31	0.21
Time of recovery room (h)	1.56±0.61	1.79±0.54	0.15
Re-intubation n (%)	1 (4)	1 (4)	0.75
Lung infection n (%)	2 (8)	1 (4)	0.50
Hospital stay d (x±s)	7.52±1.45	8.20±1.44	0.10

Numerical data are expressed as means±SD. There was no statistical difference in procedure duration, time of recovery room, re-intubation, lung infection after operation and hospital stays between two groups (P>0.05).
