Randomized Controlled Trial
Ideal Cricoid Pressure Is Biomechanically Impossible During Laryngoscopy.
This study was a prospective, randomized controlled trial of rapid sequence intubation (RSI) with cricoid pressure (CP) within the emergency department (ED). The primary aim of the study was to examine the link between ideal CP and the incidence of aspiration. ⋯ Laryngoscopy provides a counter force to CP, which is negated to facilitate tracheal intubation. The concept that a static 3.060 to 4.075 kg CP could be maintained during laryngoscopy and intubation was rejected by our study. Whether a lower CP range could prevent aspiration during RSI was not explored by this study.
