In a laparoscopic procedure, the peritoneal cavity is commonly insufflated with CO2 to what intraoperative pressure?

In laparoscopic procedures, the peritoneal cavity is typically insufflated with carbon dioxide (CO2) to a pressure that increases visibility and working space for the surgical team. The common intraoperative pressure for insufflation is in the range of 12-15 mmHg. This level is sufficient to elevate the abdominal wall away from the internal organs, facilitating the safe and effective manipulation of instruments during the procedure while minimizing the risk of complications.

Maintaining this pressure range is critical as it strikes a balance between providing adequate working space and avoiding excessive pressure that could lead to adverse effects such as compromised venous return or respiratory compromise. Pressures lower than this may not provide enough space for effective visualization, while pressures above this range can increase the risk of complications related to CO2 absorption and cardiovascular stress. This explains why the range of 12-15 mmHg is recognized as the standard for laparoscopic insufflation.
