Randomized Controlled Trial
Effect of Cricoid Pressure on the Insertion Efficacy of Six Supraglottic Devices: A Crossover Randomized Simulation Trial.
No study has ever compared the efficacy of various types of supraglottic devices (SGDs) for securing the airway under cricoid pressure. ⋯ Ventilation success rate under cricoid pressure was significantly lower than under sham pressure when using the ProSeal, Classic, and LT, but not when using the other three SGDs in both novice and experienced doctors.
