Abstract
Objective: To evaluate the influences of CO2 insufflation on changes in blo od gas analysis and end tidal CO2 tension (PetCO(2)) during posterior retro peritoneoscopic adrenalectomy in the prone position. Methods: Arterial bloo d gas analysis and measurements of PetCO2 were carried out during CO2 insuf flation in 16 patients who underwent posterior retroperitoneoscopic adrenal ectomy in the prone position (PRA group). The results were compared to 10 p atients who underwent open posterior adrenalectomy (OPA group). Ventilation was artificially controlled during the study period in all cases. Results: Arterial pH, PaCO2, PetCO(2) and PaO2 were not significantly different bet ween the PRA and OPA groups, However, the PaCO2-PetCO(2) gradient in the PR A group was significantly higher than that in the OPA group (p < 0.01). Con clusion: Transperitoneal absorption of CO2 occurs in patients undergoing re troperitoneoscopy in the prone position, The alveolo-arterial CO2 gradient may be the only parameter which indicates the absorption of CO2 during PRA.
