In emergency ambulance calls for out-of-hospital cardiac arrest (OHCA), dispatcher-assisted cardiopulmonary resuscitation (CPR) plays a crucial role in patient survival. We examined whether the language used by dispatchers to initiate CPR had an impact on callers' agreement to perform CPR. ⋯ There is potential for increased agreement to perform CPR if dispatchers are trained to initiate CPR with words of futurity and/or obligation.

This study aimed to assess long-term cognitive and functional outcomes in out-of-hospital cardiac arrest (OHCA) patients treated with targeted-temperature management, investigate the existence of prognostic factors that could be assessed during initial admission and evaluate the usefulness of classic neurological scales in this clinical scenario. ⋯ There is a high prevalence of long-term cognitive deficits and functional limitations in OHCA survivors. Most commonly used clinical scales in clinical practice are crude and lack sensitivity to detect most of these deficits.

Observational Study
How much experience do rescuers require to achieve successful tracheal intubation during cardiopulmonary resuscitation?
The cardiopulmonary resuscitation (CPR) guidelines recommend that endotracheal intubation (ETI) should be performed only by highly skilled rescuers. However, the definition of 'highly skilled' is unclear. This study evaluated how much experience with ETI is required for rescuers to perform successful ETI quickly without complications including serious chest compression interruption (interruption time <10 s) or oesophageal intubation during CPR. ⋯ Accumulated experience can improve the ETI success rate and time to successful ETI during CPR. Because ETI must be performed quickly without serious interruption of chest compression during CPR, becoming proficient at ETI requires more experience than that required for non-arrest patients. In our analysis, more than 240 experiences were required to achieve a 90% success rate of highly qualified ETI.

Only up to 20% of patients with out-of-hospital cardiac arrest (OHCA) receive immediate and optimal initial cardiac resuscitation and consequently regain consciousness soon after return of spontaneous circulation (ROSC). In the present study, we compared the outcome of conscious survivors of OHCA presenting with ST-elevation myocardial infarction (STEMI) in post-resuscitation electrocardiogram undergoing immediate invasive coronary strategy with randomly selected STEMI patients without preceding OHCA undergoing primary PCI. ⋯ Conscious survivors of OHCA with STEMI have excellent survival if they undergo immediate invasive coronary strategy. Since there is no obvious post-resuscitation brain injury in this subgroup of OHCA patients, it is probably shorter duration of myocardial ischemia driven by shorter delay from symptoms to EMS arrival that contributes to the good outcome, which is at least similar to STEMI patients without OHCA.
