Cricoid Pressure
Pronunciation: CRY-koyd
Manual pressure applied to the cricoid cartilage to compress the esophagus and prevent aspiration during intubation.
Full Definition
Cricoid pressure, also known as the Sellick maneuver, involves applying firm downward pressure on the cricoid cartilage to occlude the esophagus against the vertebral column. This technique is traditionally used during rapid sequence induction to prevent passive regurgitation and aspiration of gastric contents. In obstetric anesthesia, it is particularly relevant due to increased aspiration risk from delayed gastric emptying, increased gastric acidity, and reduced lower esophageal sphincter tone during pregnancy. However, its routine use is increasingly questioned based on recent evidence.
Usage
Usage note: Capitalize when referring to the formal technique; may be abbreviated as 'CP' in clinical documentation.
