BACKGROUND: Applying cricoid pressure is a simple and effective means of preventing aspiration of gastric juice and content. This procedure prevents a possible reflux by compressing the esophagus between the cricoid cartilage and the cervical vertebral bodies. Recent studies recommend a pressure of 30-40 N. The present study was undertaken to determine whether with education and practice, anesthesia assisitants could be taught a recommended cricoid pressure and retain this skill. METHODS: Thirty-four participants (seventeen doctors, seventeen nurses) were asked to apply pressure to the blinded model to simulate application of maneuver on three occations: before instruction, after practice and 1 month after the practice. Cricoid force was measured using a life-size model on a calibrated scale. RESULTS: Only four doctors and five nurses actually applied cricoid pressure effectively. After training, 13 doctors and 12 nurses applied cricoid pressure correctly. But they could not retain skill for 1 month. CONCLUSIONS: This model represents an easy and practical means of training the application of the optimal level cricoid pressure but the training should be continued.
