desufflation
Pronunciation: dee-suf-FLAY-shun
The controlled release of CO2 gas from the peritoneal cavity at the conclusion of laparoscopic surgery.
Full Definition
Desufflation is the process of evacuating carbon dioxide gas from the peritoneal cavity at the end of a laparoscopic procedure. This step is performed gradually while maintaining visualization to inspect for bleeding and ensure all instruments are accounted for. Complete desufflation helps reduce postoperative shoulder pain caused by residual CO2 irritating the diaphragm. The process should be controlled to prevent rapid pressure changes that could cause hemodynamic instability. Some surgeons perform active aspiration of remaining gas to minimize postoperative discomfort.
Usage
Usage note: Distinguish from general 'deflation' - specific to gas removal from body cavity.
