prolonged I:E ratio (1:1) group
prolonged inspiratory to expiratory (I:E) ratio (1:1)
80 patients are randomly allocated into two groups : prolonged I:E ratio (1:1) (n=40) and conventional I:E ratio (1:2) group (n=40). In the prolonged I:E ratio (1:1), mechanical ventilation is maintained with during I:E ratio 1:1 during steep trendelenburg with pneumoperitoneum.
conventional I:E ratio (1:2) group
conventional I:E ratio (1:2)
80 patients are randomly allocated into two groups : prolonged I:E ratio (1:1) (n=40) and conventional I:E ratio (1:2) group (n=40). In the conventional I:E ratio (1:2) group (n=40), mechanical ventilation is maintained with during I:E ratio 1:2 during steep trendelenburg with pneumoperitoneum.
