Whether mental stress negatively impacts team performance during cardio-pulmonary resuscitation (CPR) remains controversial; this may partly be explained by differences in stress measures used in previous studies. Our aim was to compare self-reported, biochemical and physiological stress measures in regard to CPR performance. ⋯ Self-reported stress (stress/overload) was the only predictor for low CPR performance. Biochemical measures showed no association, and physiological measures (heart rate) showed an inverse association, which may be due to physical activity, limiting its value as a mental stress marker in this acute setting.

Extracorporeal membrane oxygenation (ECMO) support has been suggested to improve the survival rate in patients with refractory in- and out-of-hospital cardiac arrest (IHCA and OHCA). The aim of our study is to report our experience with ECMO in these patients. ⋯ ECMO support should be considered as a resuscitation alternative in selected patients. More specifically, patients with witnessed IHCA benefit more from ECMO treatment compared to those who experience an out-of-hospital cardiac arrest.

Rapid Response Teams (RRTs) have been introduced into at least 60% of Intensive Care Unit (ICU) - equipped Australian hospitals to review deteriorating ward patients. Most studies have assessed their impact on patient outcome and less information exists on team composition or aspects of their calling criteria. ⋯ Our findings imply the likelihood of significant practice variation in relation to RRT composition, staff skill set and activation criteria between hospitals. We recommend improved resourcing of RRTs, training of the team members, and consideration for improved standardisation of calling criteria across institutions.

Post-resuscitation therapeutic hypothermia has been recommended because of its neuroprotective effects. However, a few studies have reported the effects of therapeutic hypothermia on the heart, especially in ventricular fibrillation cardiac arrest. The aim of this study was to determine whether therapeutic hypothermia attenuates post-resuscitation myocardial injury in a swine cardiac arrest model. ⋯ Therapeutic hypothermia attenuated histological myocardial injury in ventricular fibrillation cardiac arrest model of pigs while preserving more ATP and decreased apoptosis.

The underlying etiology of sudden cardiac death varies with age and is likely to be reflected in type and number of healthcare contacts. We aimed to determine the specific type of healthcare contact shortly before out-of-hospital cardiac arrest (OHCA) across ages. ⋯ Young OHCA patients are more likely to be in contact with the healthcare services compared with an age and sex matched control population suggestive of traits that make them stand out from the general population.
