insufflation
Pronunciation: in-suh-FLAY-shun
Introduction of gas into a body cavity to create working space during surgery.
Full Definition
The process of introducing gas, typically carbon dioxide, into a body cavity during minimally invasive surgery to create pneumoperitoneum and provide visualization and working space. CO2 is preferred because it absorbs rapidly into tissues and is less dangerous than air if gas embolism occurs. Insufflation pressure is carefully monitored and typically maintained at 12-15 mmHg. The procedure is essential for laparoscopic surgery but may cause post-operative shoulder pain due to diaphragmatic irritation from residual gas.
Usage
Usage note: Not to be confused with 'instillation' (liquid introduction).
In Context
