Ventricular Fibrillation Recurrences in Successfully Shocked Out-of-Hospital Cardiac Arrests.

Medicina (Kaunas) 2021 Apr 7;57(4). Epub 2021 Apr 7.

Department of Biomedical Science and Public Health, Cardiology and Arrhythmology Clinic, University Hospital "Ospedali Riuniti Umberto I-Lancisi-Salesi", Marche Polytechnic University, 60020 Ancona, Italy.

The prognostic impact of ventricular fibrillation (VF) recurrences after a successful shock in out-of-hospital cardiac arrest (OOHCA) is still poorly understood, and some evidence suggests a potential pro-arrhythmic effect of chest compressions in this setting. In the present analysis, we looked at the short-term and long-term prognosis of VF recurrences in OOHCA. And their potential association with chest compressions. Read More

Use of Public Automated External Defibrillators in Out-of-Hospital Cardiac Arrest in Poland.

Medicina (Kaunas) 2021 Mar 22;57(3). Epub 2021 Mar 22.

Department of Internal and Pediatric Nursing, Faculty of Health Sciences, Medical University of Gdańsk, 80-211 Gdańsk, Poland.

National medical records indicate that approximately 350,000-700,000 people die each year from sudden cardiac arrest. The guidelines of the European Resuscitation Council (ERC) and the International Liaison Committee on Resuscitation (ILCOR) indicate that in addition to resuscitation, it is important-in the case of so-called defibrillation rhythms-to perform defibrillation as quickly as possible. The aim of this study was to assess the use of public automated external defibrillators in out of hospital cardiac arrest in Poland between 2008 and 2018. Read More

Optimizing defibrillation during cardiac arrest.

Curr Opin Crit Care 2021 Jun;27(3):246-254

Department of Anesthesiology, Intensive Care and Emergency, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico.

Purpose Of Review: Current cardiac arrest guidelines are based on a fixed, time-based defibrillation strategy. Rhythm analysis and shock delivery (if indicated) are repeated every 2 min requiring cyclical interruptions of chest compressions. This approach has several downsides, such as the need to temporarily stop cardiopulmonary resuscitation (CPR) for a variable amount of time, thus reducing myocardial perfusion and decreasing the chance of successful defibrillation.

Rapid dispatch for out-of-hospital cardiac arrest is associated with improved survival.

Resuscitation 2021 Mar 26. Epub 2021 Mar 26.

Department of Cardiology, Nordsjællands Hospital, Dyrehavevej 29, 3400 Hillerød, Denmark; Department of Cardiology, Aalborg University Hospital, Hobrovej 18-22, 9000 Aalborg, Denmark.

Aim: As proxy for initiation of the first link in the Chain of Survival by the dispatcher, we aimed to investigate the effect of time to first dispatch on 30-day survival among patients with OHCA ultimately receiving the highest-level emergency medical response.

Methods: We linked data on all OHCA unwitnessed by emergency medical services (EMS) treated by Copenhagen EMS from 2016 through 2018 to corresponding emergency call records. Among patients receiving highest priority emergency response, we calculated time to dispatch as time from start of call to time of first dispatch. Read More

Department of Emergency Medicine, National Taiwan University Hsin-Chu Hospital, Hsinchu City, Taiwan, R.O.C.; Department of Emergency Medicine, National Taiwan University Hospital, Taipei City, Taiwan, R.O.C.. Electronic address:

Background: Out-of-hospital cardiac arrest (OHCA) is a critical condition with poor outcomes. Although the survival rate increases in those who undergo defibrillation, the utility of on-time defibrillation among bystanders remained low. An evaluation of the deployment strategy for public access defibrillators (PADs) is necessary to increase their use and accessibility. Read More

Activation of citizen responders to out-of-hospital cardiac arrest.

Curr Opin Crit Care 2021 Jun;27(3):209-215

Copenhagen Emergency Medical Services, University of Copenhagen.

Purpose Of Review: To discuss different approaches to citizen responder activation and possible future solutions for improved citizen engagement in out-of-hospital cardiac arrest (OHCA) resuscitation.

Recent Findings: Activating volunteer citizens to OHCA has the potential to improve OHCA survival by increasing bystander cardiopulmonary resuscitation (CPR) and early defibrillation. Accordingly, citizen responder systems have become widespread in numerous countries despite very limited evidence of their effect on survival or cost-effectiveness. Read More

Automatic external defibrillator provided by unmanned aerial vehicle (drone) in Greater Paris: A real world-based simulation.

Resuscitation 2021 May 22;162:259-265. Epub 2021 Mar 22.

Emergency Medical Department, Paris Fire Brigade, 1, Place Jules Renard, 75017 Paris, France.

Aim: To reduce the delay in defibrillation of out-of-hospital cardiac arrest (OHCA) patients, recent publications have shown that drones equipped with an automatic external defibrillator (AED) appear to be effective in sparsely populated areas. To study the effectiveness of AED-drones in high-density urban areas, we developed an algorithm based on emergency dispatch parameters for the rate and detection speed of cardiac arrests and technical and meteorological parameters.

Methods: We ran a numerical simulation to compare the actual time required by the Basic Life Support team (BLSt) for OHCA patients in Greater Paris in 2017 to the time required by an AED-drone. Read More
