Investigators evaluate the effect of patient position (Trendelenburg and reverse Trendelenburg) on arterial, end-tidal and transcutaneous carbon dioxide partial pressure in patients undergoing laparoscopic surgery.
Investigators evaluate the effect of patient position (Trendelenburg and reverse Trendelenburg) on arterial, end-tidal and transcutaneous carbon dioxide partial pressure in patients undergoing laparoscopic surgery. Arterial carbon dioxide partial pressure is assessed intermittently before, during, and after pneumoperitoneum. End-tidal and transcutaneous carbon dioxide partial pressure are continuously monitored.

Arterial carbon dioxide partial pressure is monitored during the laparoscopic surgery undergoing in the Trendelenburg or reverse Trendelenburg positions.
End-tidal carbon dioxide partial pressure is monitored during the laparoscopic surgery undergoing in the Trendelenburg or reverse Trendelenburg positions.
Transcutaneous carbon dioxide partial pressure is monitored during the laparoscopic surgery undergoing in the Trendelenburg or reverse Trendelenburg positions.
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)
Time frame: baseline before CO2 pneumoperitoneum, every 30 minute during CO2 pneumoperitoneum, and 15 min after deflation of CO2
Agreement among arterial, end-tidal, and transcutaneous carbon dioxide partial pressure
Arterial, end-tidal, and transcutaneous carbon dioxide partial pressures are recorded and the agreement among the values is analyzed using the statistical test.
Time frame: baseline before CO2 pneumoperitoneum, every 30 minute during CO2 pneumoperitoneum, and 15 min after deflation of CO2
