Einfluss der Basisreanimationsmaβnahmen durch Laien auf das Überleben nach plötzlichem Herztod

Abstract

Background. Bystander cardiopulmonary resuscitation (CPR) is mandatory to shorten no-flow time. The present study aimed to evaluate the factors age, gender, etiology and location of out-of-hospital cardiac arrest (OHCA) in relation to bystander CPR based on the German resuscitation registry (GRR) database.Methods. Retrospective analyses from the German resuscitation registry including data from adult OHCA patients registered from 01/2004 to 07/2011 (n = 11,788). The data set preclinical care included demographic factors, presumed etiology, location of collapse, any return of spontaneous circulation (ROSC) and survival to hospital admission.Results. Patients with OHCA witnessed by bystanders (n = 5,659) received bystander CPR significantly more often compared with non-witnessed OHCA (p < 0.01; OR: 4.19; CI 95% 3.70-4.67) and had significantly increased ROSC (p < 0.01) and survival to hospital admission (p < 0.01). The incidence of bystander CPR was highest in younger patients (18-20 years; 25%) and lowest in elderly patients (> 80 years; 12%). Bystander CPR of witnessed OHCA was performed significantly less often at private homes compared with public areas (p < 0.01, OR: 0.37; CI95% 0.33-0.42).Conclusions. Lay people initiate CPR independently from witnessing in OHCA patients who are younger than 20 years and where OHCA occurred at the workplace. Considering the high number of OHCA witnessed by lay persons but the generally poor incidence of bystander CPR in the case of witnessing, in particular at non-public areas, modifications in bystander CPR training strategy are needed. © Springer-Verlag Berlin Heidelberg 2012.
