capnoperitoneum
Pronunciation: cap-no-pair-ih-toe-NEE-um
The intentional insufflation of carbon dioxide gas into the peritoneal cavity to create working space for laparoscopic surgery.
Full Definition
The deliberate introduction of carbon dioxide gas into the peritoneal cavity during laparoscopic procedures to create pneumoperitoneum. CO₂ is preferred over other gases because it is highly soluble in blood and rapidly absorbed, reducing the risk of gas embolism. The term specifically refers to CO₂ insufflation, distinguishing it from pneumoperitoneum achieved with other gases or air.
Usage
Usage note: Use when specifically referring to CO₂ insufflation; 'pneumoperitoneum' is the broader term.
