Cricoid pressure, also known as the Sellick maneuver, is specifically utilized during endotracheal intubation to prevent aspiration of gastric contents into the lungs. This technique involves applying downward pressure on the cricoid cartilage, which helps occlude the esophagus and minimizes the risk of regurgitation. This is particularly crucial in patients who are unable to protect their airways, such as those under general anesthesia or those with a full stomach, where the risk of aspiration is heightened.

While cricoid pressure may be present during surgery if intubation has occurred, its primary purpose and protocol is associated with the intubation process itself rather than during the surgical procedure. The other options, including pre-operative assessment and post-operative care, do not necessitate cricoid pressure as they are not directly associated with the immediate risk of airway management linked to intubation.
