What is the initial flow rate for insufflation during laparoscopic procedures?

  1. 5 L/min

  2. 9 L/min

  3. 10 L/min

  4. 6 L/min

The correct answer is: 9 L/min

In laparoscopic procedures, the initial flow rate for insufflation is typically set to facilitate the establishment of a working space within the abdominal cavity. A flow rate of about 9 L/min is commonly regarded as effective for this purpose, allowing for rapid establishment of the necessary insufflation without compromising patient safety or the integrity of the abdominal wall. This rate helps to ensure that the CO2 insufflation fills the cavity quickly, enabling visualization and access to the surgical area while allowing for adjustments based on specific procedural needs. Higher or lower settings may not be ideal as they can either lead to inadequate insufflation or excessive pressure within the abdominal cavity, both of which can pose risks during the surgical procedure. Hence, an initial setting of 9 L/min is utilized for its balance between speed and safety, making it the correct answer in the context of standard practices in laparoscopic surgery.
