Final answer:
Carbon dioxide (CO2) is the gas most commonly infused into the abdominal cavity during laparoscopic surgeries to create space for the procedure.
Step-by-step explanation:
During laparoscopic procedures, a specific type of gas is infused into the abdominal cavity to create space between the abdominal organs and the abdominal wall, allowing surgeons visibility and room to operate. The most commonly used gas for this purpose is carbon dioxide (CO2). Carbon dioxide is preferred because it is non-flammable, which is important to prevent fire hazards during surgery involving electric cautery. Moreover, CO2 is readily absorbed by tissue and easily removed by the respiratory system, minimizing the risk of gas embolisms when compared to air or other gases.
Oxygen, nitrogen, and helium are not typically used in laparoscopic procedures. Oxygen is highly combustible, which increases the risk of fires during surgeries. Nitrogen is the main component of air and is less soluble in blood than CO2, posing a higher embolism risk. Helium has been used in special situations but is not the standard as its benefits do not significantly outweigh those of CO2 for most procedures
In summary, carbon dioxide is the gas infused into the abdominal cavity during laparoscopic surgeries, which helps to provide an optimal environment for minimally invasive surgery.
The type of gas typically infused into the abdominal cavity for laparoscopic procedures is carbon dioxide (CO2).
