Abstract
BackgroundHigh quality chest compressions (CCs) are of crucial importance during cardio-pulmonary resuscitation (CPR). Currently, there are no clear evidences that the use of automatic chest compression devices (ACCD) are superior to manual CCs during out-of-hospital CPR. This study aimed to estimate if availability of ACCDs for two-man rescue teams had any impact on CPR efficiency and a rate of successful transport of patients after out-of-hospital cardiac arrest (OHCA) to emergency departments.MethodsThe study was designed as a retrospective cohort study. The research tool was the analysis of medical charts of Emergency Medical Service (EMS) in one million agglomeration in Poland in 2018. ACCDs were available for two-man paramedical teams in a half of ambulances and this fact was criterion of group division [ACCD (n=181) and manual CC (MCC) (n=303)]. The following variables such as gender (male/female), age, area of intervention (town/countryside), return of spontaneous circulation (ROSC) followed by successful transport to hospital were compared between subgroups.ResultsAmong 71,282 interventions in 2018, there were 484 resuscitations undertaken with complete medical data. ROSC and transport to hospital was achieved in 54.9% of individuals, statistically more often among ACCD subjects (63.5%) than those compressed manually (49.8%) (P=0.003). Moreover, the use of ACCD was associated with higher chances of ROSC in younger patients (P=0.027) and if cardiac arrest had place in the town centre (P=0.002).ConclusionsOur observation revealed that the use of ACCD in the pre-hospital emergency care involving two-man rescue teams may increase the prevalence of ROSC among OHCA patients.
