Experimental: Equal-ratio ventilation(ERV) group
ventilator inspiration to expiration ratio will be set 1:1.
Other: Equal ratio ventilation(ERV)
Set the inspiratory to expiratory ratio 1:1 during mechanical ventilation
Other Name: I:E ratio 1:1
Active Comparator: Control group
ventilator inspiration to expiration ratio will be set 1:2.
Other: I:E Ratio "1:2
Set the inspiratory to expiratory ratio 1:2 during mechanical ventilation
- The amount of intraoperative surgical bleeding [ Time Frame: At the end of the surgery, approximately 4 hrs. ]The surgical blood loss was compared in the two groups (ERV vs. conrol) during posterior lumbar interbody fusion(PLIF) in prone position.
