Why the study?

Does extraperitoneal CO2 insufflation increase pulmonary CO2 elimination more than intraperitoneal CO2 insufflation in patients undergoing surgical procedures?

Population

30 patients undergoing surgical procedures under general anesthesia with controlled mechanical ventilation

Comparison

Extraperitoneal CO2 insufflation vs Intraperitoneal CO2 insufflation

Design

Cohort

Follow-up

Intraoperative

Implication

Extraperitoneal insufflation markedly elevates CO2 elimination versus intraperitoneal; hypothesis-generating for adjusted ventilation but should not yet change practice.

Structured PICO

Does extraperitoneal CO2 insufflation increase pulmonary CO2 elimination more than intraperitoneal CO2 insufflation in patients undergoing surgical procedures?

Population

30 patients undergoing surgical procedures under general anesthesia with controlled mechanical ventilation (10 gynecologic laparoscopy, 10 laparoscopic cholecystectomy, 10 pelviscopy)

Intervention

Extraperitoneal CO2 insufflation (during pelviscopy for 45 +/- 3 min)

Comparator

Intraperitoneal CO2 insufflation (during gynecologic laparoscopy for 43 +/- 4 min or laparoscopic cholecystectomy for 125 +/- 14 min)

Outcome

End-tidal CO2 tension (PETCO2) and pulmonary CO2 elimination (VECO2)surrogate

CO2 diffusion into the body is significantly more marked during extraperitoneal than during intraperitoneal CO2 insufflation, independent of the duration of intraperitoneal insufflation.
