Trethewy CE, et al. - Authors performed a prospective, randomised controlled trial of Rapid Sequence Intubation (RSI) with Cricoid Pressure (CP) within the Emergency Department (ED) to explore the association between ideal CP and the incidence of aspiration. They recognized that laryngoscopy provided a counter force to CP which was negated in order to facilitate tracheal intubation. This study rejected the concept that a static 3.060 kg- 4.075kg CP could be maintained during laryngoscopy and intubation. Whether a lower CP range could prevent aspiration during RSI require further exploration.
