capnoperitoneum
Pronunciation: KAP-noh-pair-ih-toh-NEE-um
The intentional introduction of carbon dioxide gas into the peritoneal cavity to create working space during laparoscopic surgery.
Full Definition
Capnoperitoneum refers to the controlled insufflation of carbon dioxide into the abdomen to distend the peritoneal cavity, creating a safe working environment for laparoscopic procedures. CO2 is preferred because it absorbs rapidly into tissues and is eliminated through respiration, reducing the risk of gas embolism compared to other gases. The pressure is typically maintained between 12-15 mmHg during surgery. This technique allows surgeons to safely manipulate instruments while maintaining clear visualization of anatomical structures. The term combines 'capno' (carbon dioxide) with 'peritoneum' (abdominal lining).
Usage
Usage note: Often shortened to 'pneumoperitoneum' in casual surgical discussion, though capnoperitoneum is more precise.
