MAP, mean arterial pressure; PR, pulse rate; Group NC, SITS without CO2 insufflation; Group C, SITS with CO2 insufflation; FTV, full tidal volume ventilation (10 mL/kg tidal volume); STV, small tidal volume ventilation (5 mL/kg tidal volume); CO2 with STV, CO2 insufflation with small tidal volume ventilation in group C or at the same time without CO2 in group NC; FTV restored, full tidal volume ventilation after surgery with small tidal volume; TLV, two-lung ventilation.
