[Effect of CO2 insufflation into the peritoneal cavity on selected indices of respiratory system function during...

An attempt was undertaken at evaluation of the influence of CO2 insufflation in patients subjected to laparoscopic cholecystectomy on pulmonary dynamic compliance, pulmonary resistance, pressures in the airways, CO2 pressure in expired air, and arterialized blood gas analysis. The studies were carried out in a group of 33 patients, including 26 women and 7 men, evaluated according to ASA scale as I/II degrees. The means of the values obtained before CO2 insufflation into the peritoneal cavity were compared with the means from the period of pneumoperitoneum maintenance. Statistically significant decrease of pulmonary compliance, increase of the mean pressure in the airways and increase of CO2 pressure both in expired air and arterialized blood were demonstrated. Pulmonary resistance and oxygen pressure in blood remained without statistically significant changes. The attention was paid to the rationale of including capnometry to the standard monitoring equipment during laparoscopic operations.
