Outcome Measures

Primary Outcomes (1)

  • cerebral ischemia

    induction 10 min, Pneumoperitoneum 20 min, after PEEP apply 40 min, time of operation ending cerebral oxymetry, cerebral perfusion pressure record

    change from baseline in rSO2 at every events

Study Arms (2)

zero end-expiratory pressure

PLACEBO COMPARATOR

not applying PEEP during operation just applying TV=IBW\*6-8ml IBW = (male; 50+0.91\[(Ht-cm)-152.4\], female; 45.5 +0.91\[(Ht-cm)-152.4\], RR 8-12/min,

Procedure: positive end expiratory pressure

positive end expiratory pressure

ACTIVE COMPARATOR
