Which characteristic of CO2 gas is acute during abdominal insufflation in laparoscopy?

The correct choice revolves around the characteristic of carbon dioxide (CO2) gas that makes it particularly suitable for abdominal insufflation during laparoscopic procedures. CO2 is known for its better solubility in blood compared to other gases that could be used for insufflation, such as nitrogen or helium. This solubility is crucial because during laparoscopy, CO2 can be readily absorbed by the body if there is any extravasation into the vascular system, thereby minimizing complications like gas embolism, which can occur if less soluble gases are used.

The solubility of CO2 allows it to be easily transported in the bloodstream, where it can be safely eliminated through respiration. This minimizes the risk of intraoperative complications and aids in maintaining hemodynamic stability during the procedure.

Factors such as lower pressure levels, no reactivity, or higher viscosity are less pertinent in this context. For instance, lower pressure levels would imply less effective insufflation, while the reactivity of the gas is not a primary concern in a controlled surgical environment where CO2 is utilized. Higher viscosity could also present issues with ease of passage through instruments and would not assist in the goal of creating an adequate working space during the procedure.
