Maneuver

Interventions/Control_1

Volume control ventilation group
Targer PaO2>100 mmHg and PaCO2<50 mmHg.

Volume control ventilation mode.
I:E ratio of 1:2.
PEEP of 5 cmH2O.
Tidal volume of 6~8 ml/kg body weight.
Airway pressure < 30 cmH2O.
Initial respiratory rate of 12 bpm up to 18 bpm.

Interventions/Control_2

Expiratory flow initiated pressure control inverse ratio ventilation group
Targer PaO2>100 mmHg and PaCO2<50 mmHg.

PCV volume guarantee mode.
PEEP off.
Tidal volume of 6~10 ml/kg body weight.
Airway pressure < 25 cmH2O.
Inverse I/E ratio was adjusted individually by observing the expiratory flow-time wave.
Initial respiratory rate of 12 bpm up to 15 bpm.

Results

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.
