Randomized Controlled Trial Multicenter Study
Effects of intra-resuscitation antiarrhythmic administration on rearrest occurrence and intra-resuscitation ECG characteristics in the ROC ALPS trial.
Intra-resuscitation antiarrhythmic drugs may improve resuscitation outcomes, in part by avoiding rearrest, a condition associated with poor out-of-hospital cardiac arrest (OHCA) outcomes. However, antiarrhythmics may also alter defibrillation threshold. The objective of this study was to investigate the relationship between rearrest and intra-resuscitation antiarrhythmic drugs in the context of the Resuscitation Outcomes Consortium (ROC) amiodarone, lidocaine, and placebo (ALPS) trial. ⋯ Rearrest rates did not differ between antiarrhythmic and placebo treatment groups. ECG waveform characteristics were correlated with treatment group and rearrest. Rearrest was inversely associated with survival and neurologic outcomes.

Multicenter Study Observational Study
Comparison of presumed cardiac and respiratory causes of out-of-hospital cardiac arrest.
Most interventional and observational studies include cardiac arrest from cardiac origin. However, an increasing proportion of cardiac arrest results from an extra-cardiac origin, mainly respiratory. The aim of our study was to compare the characteristics and outcome of cardiac arrest patients according to the presumed cardiac or respiratory causes. ⋯ Compared to presumed cardiac origin, a worse outcome and a different mode of death are associated with the presumed respiratory origin, resulting from a greater insult preceding cardiac arrest. The presumed cause of cardiac arrest could be integrated in the multimodal prognostication process.

Adherence to advanced cardiovascular life support (ACLS) guidelines during in-hospital cardiac arrest is associated with improved outcomes.
Identifying modifiable factors associated with survival following in-hospital cardiac arrest is crucial. The purpose of this study was to determine the extent to which adherence to the 2010 American Heart Association (AHA) Advanced Cardiac Life Support (ACLS) guidelines in their entirety affects patient outcomes. In addition, we explored the role of code leader training level on patient outcomes. ⋯ We found that higher numbers of deviations from ACLS guidelines were associated with a lower likelihood of ROSC and survival to hospital discharge. These findings emphasize the importance of adherence to ACLS guidelines and the need for training healthcare personnel in resuscitation guidelines in order to improve outcomes for victims of in-hospital cardiac arrest.

Multicenter Study
Resuscitation registers: How many active registers are there and how many collect data on paediatric cardiac arrests?
Cardiac arrest, particularly in children, often has a poor outcome and international guidelines highlight significant gaps in the evidence base for effective resuscitation. Whilst randomised controlled trials for some interventions can be justified, they are not appropriate for many aspects of resuscitation. Therefore, guidelines must use other sources of data such as epidemiological evidence from cardiac arrest registries, to improve the efficacy of resuscitation. The aim of our study was to identify existing national cardiac arrest registries and document key information about the registries, including whether they contain data on paediatric arrests. ⋯ To our knowledge this report contains the most complete list of active national and large regional cardiac arrest registries. Register data support current guidelines on effective resuscitation however, even the largest registries include relatively small numbers, particularly of paediatric events. A less fragmented approach has the potential to improve the utility of registration data for the benefit of patients.

Multicenter Study Observational Study
Effect of detection time interval for out-of-hospital cardiac arrest on outcomes in dispatcher-assisted cardiopulmonary resuscitation: A nationwide observational study.
The association between the detection time interval (DTI) from the call for ambulance to the detection of out-of-hospital cardiac arrest (OHCA) by the dispatcher and the neurological outcome in dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) is unclear. ⋯ A longer DTI in DA-CPR showed significantly lower good neurological recovery in adult patients with witnessed OHCA. A 30 s delay in DTI was associated with a 3% decrease of a good CPC score. The DTI effect on good CPC was significant in metropolis and Rural province while not in megacity region.
