Comparison of Minimum Flow and Low Flow Desflurane Anesthesia in Robotic Assisted Laparoscopic Abdominal Surgery

"1. Airway pressure (P plateau, Ppeak) values are taken from the anesthesia device data,~2. BIS (from routine BIS monitoring)~3. Temperature (routinely from pharyngeal temperature probe),~4. Oxygen saturation (routinely from the patient monitor)~5. End-tidal CO₂,~6. inspiratory O₂ concentration,~7. Inspiratory CO2 concentration,~8. inspiratory and expiratory desflurane concentrations,~9. tidal volume,~10. MAC is routinely obtained from anesthesia device data.~11. Blood Gas Analysis (COHgb, Ph, PO2, PCO2, SaO2, HCO3, Base deficit, glucose, lactate)"
