Conditions

Outcome Measures

Primary Outcomes (1)

  • Difference between arterial and end-tidal carbon dioxide pressures

    Difference between arterial and end-tidal carbon dioxide partial pressures are calculated. (Arterial carbon dioxide partial pressure minus end-tidal carbon dioxide partial pressure)

    baseline before CO2 pneumoperitoneum, every 30 minute during CO2 pneumoperitoneum, and 15 min after deflation of CO2

Secondary Outcomes (1)

  • Agreement among arterial, end-tidal, and transcutaneous carbon dioxide partial pressure

    baseline before CO2 pneumoperitoneum, every 30 minute during CO2 pneumoperitoneum, and 15 min after deflation of CO2

Study Arms (2)

Trendelenburg group

ACTIVE COMPARATOR

Arterial, end-tidal, and transcutaneous carbon dioxide partial pressure are monitored in the Trendelenberg position

Other: Arterial carbon dioxide monitoringOther: End-tidal carbon dioxide monitoringOther: Transcutaneous carbon dioxide monitoring

reverse Trendelenburg group

ACTIVE COMPARATOR

Arterial, end-tidal, and transcutaneous carbon dioxide partial pressure are monitored in the reverse Trendelenberg position

Other: Arterial carbon dioxide monitoringOther: End-tidal carbon dioxide monitoringOther: Transcutaneous carbon dioxide monitoring

Interventions

Arterial carbon dioxide partial pressure is monitored during the laparoscopic surgery undergoing in the Trendelenburg or reverse Trendelenburg positions.
