Abstract 14078: Efficacy of the 2010 CPR Guidelines for Patients With Out-of-Hospital Cardiac Arrest due to Ventricular Fibrillation
Introduction: The 2010 guidelines for cardiopulmonary resuscitation (CPR) stressed that it is necessary to improve CPR quality. It is not known whether the neurologically intact survival rate will increase if lay rescuers and/or emergency medical service (EMS) personnel perform the CPR procedures according to the 2010 guidelines. We divided the period of each guidelines in the first half and the second half, and compared the first half and the second half.
Methods: From the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of out-of-hospital cardiac arrest (OHCA), we included adult patients who had bystander-witnessed OHCA due to cardiac etiology and in whom shockable arrest was recorded as an initial rhythm. Study patients were divided into two groups based on the different CPR guidelines; the 2005 guidelines (2005G), and 2010 guidelines (2010G). The primary endpoint, favorable neurological outcome at 30 days after OHCA, was compared between the first half and the second half in the two groups
Results: Of the 24,587 patients who met the inclusion criteria, 11,380 received electrical therapy in 2005G, and 13,207 in 2010G. The figure shows the comparison of favorable neurological outcome between the first half and the second half in the two groups. Adjusted odds ratios for favorable neurological outcome were 1.4 (95% CI, 1.3 to 1.5) after the 2010G group as compared with the 2005G group.
Conclusions: In terms of neurological benefits, the CPR protocol of the 2010 guidelines were superior to the others in patients with shockable, and the second half of the period of each guidelines were superior to the first half.
