Systematic Review and Meta-Analysis of Cricoid Pressure Training and Education Efficacy

We examined the evidence on the effectiveness of education and training on cricoid pressure (ie, Sellick maneuver) application. Cricoid pressure is used during rapid sequence induction and intubation to reduce the risk of pulmonary aspiration. We searched seven databases for studies on the education and training of health care personnel expected to apply cricoid pressure as a part of their regular clinical responsibilities. We appraised the included studies using standardized tools validated for this purpose and we performed a meta-analysis of the eight eligible studies. The success rate for intubation increased after training according to the random effect model (95% CI = 0.157 to 0.452). Fisher's method combined probability test rejected the null hypothesis for patients (P = 4.93e-6), indicating that the application of cricoid pressure significantly improved after educational interventions. Regularly scheduled training in the application of cricoid pressure could sustain health care personnel's ability to apply effective cricoid pressure.
