This study describes the epidemiology of sudden cardiac arrest patients in Victoria, Australia, as captured via the Victorian Ambulance Cardiac Arrest Register (VACAR). We used the VACAR data to construct a new model of out-of-hospital cardiac arrest (OHCA), which was specified in accordance with observed trends. ⋯ The new model accounts for relationships among predictors of survival. These relationships indicate that interventions such as reduced response times and bystander CPR act in multiple ways to improve survival.

Trauma management systems have grown in response to regional variations in trauma population, geographical conditions and the provisions of care. National Trauma Registries are being established to improve patient outcomes. However international comparisons could provide the potential to record regional performance, identify and share examples of best practice. To assess whether it was possible to compare data currently being collected by a number of trauma services across Europe, a group was established to develop a common core dataset and to assess the feasibility of collecting anonymised data. ⋯ It is possible to collect and collate outcome data from established trauma registries across Europe with minimal additional infrastructure using a web-based system. Initial analysis of the results reveals significant international variations. The network has potential as a source of data for epidemiological and clinical research and for optimal trauma system design across Europe.

Delivering alternating currency (AC) to right ventricular endocardium to induce ventricular fibrillation (VF) in mice is complicated. We tried to validate whether transoesophageal AC stimulation could induce VF and how long AC stimulation had to be sustained to prevent the spontaneous cardioversion of VF in mice. ⋯ VF can be induced by a short period of transoesophageal AC stimulation in mice. However, prolonged AC stimulation is prone to induce PEA other than VF. Nonetheless, the development of a mouse CA model in this manner is simpler and easier, which may have practical significance for facilitating experimental investigation on CA and CPR.
