cricoid pressure
Pronunciation: CRY-coid PRESH-ur
Manual pressure applied to the cricoid cartilage to prevent aspiration during rapid sequence induction.
Full Definition
Cricoid pressure, also known as the Sellick maneuver, involves applying firm downward pressure to the cricoid cartilage to compress the esophagus against the vertebral column, theoretically preventing passive regurgitation and pulmonary aspiration during rapid sequence induction. In pediatric anesthesia, the technique requires modification due to anatomical differences, with lighter pressure (approximately 20-30 Newtons) applied compared to adults. The efficacy and safety of cricoid pressure have been questioned in recent literature, and its use is becoming more selective based on individual patient risk factors.
Usage
Usage note: Document both application and release of cricoid pressure in anesthetic records
