Observational Study
Detection and quantification of gasping during resuscitation for out-of-hospital cardiac arrest.
To detect and quantify gasping during cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA) patients and to investigate whether gasping is associated with increased return of spontaneous circulation (ROSC). ⋯ The occurrence of gasping during CPR was high. Significant gasping volumes were measured. The presence or absence of gasping was not associated with ROSC, but higher gasping rate and deeper negative pressures were.

Respective proportions of final etiologies are disparate in cohorts of cardiac arrest patients, depending on examined population and diagnostic algorithms. In particular, prevalence and characteristics of sudden unexplained death syndrome (SUDS) are debated. We aimed at describing etiologies in a large cohort of aborted out-of-hospital cardiac arrest (OHCA) patients, in order to assess prevalence and outcome of SUDS. ⋯ We observed that ischemic heart disease was by far the most common cause of cardiac arrest, while primary electrical diseases were much less frequent. SUDS accounted for a very small proportion of patients who suffered an aborted OHCA.

Observational Study
Epileptiform discharge detection with the 4-channel frontal electroencephalography during post-resuscitation care.
We performed this study to investigate whether the SEDline system, a 4-channel-processed electroencephalography (EEG) monitoring device in the frontal area, can detect epileptiform discharges accurately during post-resuscitation care in comatose cardiac arrest survivors. ⋯ The SEDline system detected epileptiform discharges accurately in comatose cardiac arrest survivors during post-resuscitation care.

Some patients with out-of-hospital cardiac arrest (OHCA) assessed by emergency medical services (EMS) do not receive attempts at resuscitation on the basis of perceived futility. ⋯ The proportion of patients with OHCA who receive resuscitation attempts is variable across EMS agencies and is associated with EMS response interval, ALS unit availability and geographic region. On average, survival was higher among EMS agencies more likely to initiate resuscitation.
