Effect of Positive End Expiratory Pressure (PEEP) on Cerebral Oxymetry During Laparoscopy

Not Applicable
Completed
Conditions
Cerebral Ischemia
Interventions
Procedure: positive end expiratory pressure
Procedure: zero end-expiratory pressure
Registration Number
NCT01436812
Lead Sponsor
Gachon University Gil Medical Center
Brief Summary

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

Detailed Description

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