What is the purpose of the Sellick maneuver during intubation?

The Sellick maneuver, also known as cricoid pressure, is primarily used to minimize the chances of regurgitation during intubation. The technique involves applying pressure to the cricoid cartilage, which compresses the esophagus and helps to prevent the aspiration of gastric contents into the trachea. This is particularly important in pediatric patients who may have a full stomach or other risk factors for aspiration.

By preventing regurgitation, the Sellick maneuver aims to reduce the risk of aspiration pneumonia and other complications that can arise from accidentally introducing stomach contents into the airway. Thus, the maneuver is an essential practice in ensuring the safety of the patient during the intubation process, especially in emergency situations where securing the airway is critical.

While improving visualization of the vocal cords and ensuring effective ventilation are also important aspects of intubation, these are not the primary focus of the Sellick maneuver. Instead, this technique specifically targets the prevention of regurgitation, highlighting its role in airway management.
