  Purpose
During the laparoscopic cholecystectomy, Pneumoperitoneum could affect to the regional oxygen saturation of brain. positive end expiratory pressure (PEEP)could improve the respiratory parameters include oxygenation. So applying PEEP could improve the regional brain oxygen saturation (rSO2)

Condition Intervention
Brain Ischemia Other: PEEP Other: ZEEP

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Prevention
Official Title: The Effect of PEEP on Regional Cerebral Oxygen Saturation During Laparoscopic Cholecystectomy

Primary Outcome Measures:
  • change in regional brain oxygen saturation [ Time Frame: from baseline record rSO2 every 10 minutes ]
    FiO2 0.6, Tidal vlume 8 ml/IBW (kg), PEEP 10 cm H2O or not, respiratory rate as end-tidal carbone dioxide concentration (ETCO2). During the peumoperitoneum record rSO2 every 10 minutes with respiratory parameters (Peak pressure, mean pressure, PEEP) and vital signs


Enrollment: 60
Study Start Date: November 2011
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Zero positive end expiratory pressure
Number: 30, apply no PEEP during the pneumoperitoneum during the laparoscopic cholecystectomy PEEP was not applied whole investigation period
Other: PEEP
applying PEEP 0 cmH2O during pneumoperitoneum continuously
Other Name: PEEP 0
Active Comparator: positive end expiratory pressure
applying PEEP 10 cmH2O during pneumoperitoneum continuously
Other: ZEEP
applying PEEP 10 cmH2O during pneumoperitoneum continuously
Other Name: PEEP 10

Detailed Description:
During the laparoscopic cholecystectomy, Pneumoperitoneum could affect to the regional oxygen saturation of brain due to increased intracranial pressure, central venous pressure and make worse to respiratory parameters. Positive end expiratory pressure could improve the respiratory parameters include oxygenation. So applying PEEP could improve the regional oxygen saturation of brain during the pneumoperitoneum during the laparoscopic cholecystectomy.
