insufflation
The process of introducing gas (typically CO2) into the peritoneal cavity to create working space during laparoscopic surgery.
Full Definition
Insufflation is the controlled introduction of carbon dioxide gas into the peritoneal cavity to distend the abdomen and create adequate visualization and working space for laparoscopic procedures. The gas is introduced through a small incision, typically at the umbilicus, and maintained at specific pressures (usually 12-15 mmHg) throughout the procedure. Proper insufflation technique is critical for patient safety and surgical success, as excessive pressure can compromise cardiovascular and respiratory function.
Usage
Usage note: Often confused with 'inflation' in medical writing; insufflation specifically refers to gas introduction into body cavities.
