Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ventilation Group
Volume controlled ventilation was done during the whole surgery.
Lung Ventilation
In the ventilated group, mechanical ventilation was done with the half of the initial tidal volume (i.e. 3-4 ml/kg, 250-300ml) during the aortic cross-clamp.
Non-ventilation Group
In the non-ventilated group lungs were collapsed after completion of CPB until after weaning from the extracorporeal circulation.
Non-ventilated Group
. In the non-ventilated group lungs were collapsed after completion of CPB until after weaning from the extracorporeal circulation.
