Background:This study examined the association between prehospital supraglottic airway (SGA) and/or epinephrine compared with bag-mask ventilation (BMV) and Glasgow–Pittsburgh cerebral performance category (CPC) 1 status in patients with out-of-hospital cardiac arrest (OHCA) using a large, nationwide, population-based registry dataset.
Methods and Results:This was a post hoc analysis of the All-Japan Utstein Registry. We included patients with OHCA of cardiac origin aged ≥18 years with resuscitation performed by emergency medical services (EMS) between January 2011 and December 2015. The primary endpoint was favorable neurological outcome (CPC 1). The patients were divided into 4 groups according to the prehospital management performed by EMS: BMV group received only basic life support (BLS); epinephrine group received BLS plus epinephrine; SGA group received BLS plus SGA; and combined group received BLS plus epinephrine and SGA. Univariate and multivariable logistic regression analyses were performed for the primary endpoint. Among the 106,434 patients with OHCA, 48,847 received only BMV, 8,958 received BLS+epinephrine, 25,467 received BLS+SGA, and 15,551 received BLS+epinephrine+SGA. Using the BMV group as the reference, multivariable analysis showed that the epinephrine, SGA, and combined groups were independently associated with a reduced incidence of favorable neurological outcomes.
Conclusions:Our results indicated that compared with BLS, patients in the prehospital SGA and/or epinephrine groups had a significantly reduced incidence of CPC 1 status.
