History of Changes
  Purpose

The investigators hypothesized that positive end expiratory pressure (PEEP) would increase the regional oxygen saturation (rSO2).


Condition Intervention
Cerebral Ischemia
 Procedure: positive end expiratory pressure

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Prevention
Official Title: International Reveiw Board of Gachon Univerity Gil Hospital

Further study details as provided by Gachon University Gil Medical Center:

Primary Outcome Measures:
  • cerebral ischemia [ Time Frame: change from baseline in rSO2 at every events ] [ Designated as safety issue: Yes ]
    induction 10 min, Pneumoperitoneum 20 min, after PEEP apply 40 min, time of operation ending cerebral oxymetry, cerebral perfusion pressure record


Estimated Enrollment: 30
Study Start Date: September 2011
Estimated Study Completion Date: September 2012
Estimated Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: zero end-expiratory pressure
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 10 cm H2O during peumoperitoneum
Other Name: PEEP
Active Comparator: positive end-expiratory pressure
applying PEEP 10 cmH2O 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 10 cm H2O during peumoperitoneum
Other Name: PEEP

Detailed Description:

The investigators hypothesized that PEEP would increase the rSO2 during laparoscopic surgery by improving oxygenation.
