Multicenter Study Comparative Study
Hyperoxia in the intensive care unit and outcome after out-of-hospital ventricular fibrillation cardiac arrest.
Laboratory and clinical studies have suggested that hyperoxia early after resuscitation from cardiac arrest may increase neurological injury and worsen outcome. Previous clinical studies have been small or have not included relevant prehospital data. We aimed to determine in a larger cohort of patients whether hyperoxia in the intensive care unit in patients admitted after out-of-hospital cardiac arrest (OHCA) was associated with increased mortality rate after correction for prehospital variables. ⋯ Hyperoxia within the first 24 hours was not associated with increased hospital mortality in patients admitted to ICU following out-of-hospital ventricular fibrillation cardiac arrest.

Comparative Study
A comparison of survival following out-of-hospital cardiac arrest in Sydney, Australia, between 2004-2005 and 2009-2010.
To determine whether survival following out-of- hospital cardiac arrest (OHCA) in Sydney, Australia, improved between 2004-2005 and 2009-2010, and whether there was a change in incidence of OHCA. ⋯ There was no improvement in survival following OHCA in Sydney between 2004-2005 and 2009- 2010. There has been a decrease in overall survival from OHCA and a decrease in the overall age-standardised incidence of OHCA. The decrease in overall survival may be due to a decline in the incidence of VF.
