There were no significant differences in serum IL-6 and IL-8 levels between the groups.
The physiological dead space ratio in the EF-initiated PC-IRV group was significantly smaller than that in the VCV group.
The physiological dead space ratio was also negatively correlated with preoperative FVC (% predicted) in the VCV group, but not correlated in the EF-initiated PC-IRV group.
Two patients required permissive hypercapnia in the VCV group, but not in the EF-initiated PC-IRV group.
