Effect of Incorrectly Applied Cricoid Pressure During Rapid Sequence Induction. Evaluation With High-resolution Manometry.

Not Applicable

Completed

• Conditions: Cricoid Pressure
• Interventions: Procedure: Cricoid Pressure

• Registration Number: NCT02161601
• Lead Sponsor: Örebro University, Sweden

Brief Summary

During emergency anesthesia (rapid sequence induction) , a firm pressure is applied to the cricoid cartilage of the patient in order to prevent passive regurgitation of gastric content into the pharynx. This maneuver is called cricoid pressure.

Cricoid pressure is often performed incorrectly, due to difficulties to locate the cricoid cartilage in many patients. Despite this, the effectiveness of an incorrectly applied cricoid pressure has not been investigated. In this study we have used high-resolution manometry (HRM) to evaluate pressures in the upper esophagus during correctly applied cricoid pressure (against the cricoid cartilage) compared to incorrectly applied cricoid pressure (against the thyroid cartilage and against the trachea) during a rapid sequence induction.
