Comparative Study
Efficacy of bystander CPR: intervention by lay people and by health care professionals.
Early cardiopulmonary resuscitation (CPR) by bystanders prior to the arrival of the rescue team has been shown to be associated with increased survival after out-of-hospital cardiac arrest. The aim of this survey was to evaluate the impact on survival of no bystander CPR, lay bystander CPR and professional bystander CPR. ⋯ Among patients suffering an out-of-hospital cardiac arrest, bystander CPR by lay persons (excluding health care professionals) is associated with an increased chance of survival. Furthermore, there is a distinction between lay persons and health care providers; survival is higher when the latter perform bystander CPR. However, these results may not be explained by differences in the quality of CPR.

To evaluate the efficacy of HBOC-201 for resuscitation of hemorrhagic shock in a swine model incorporating soft tissue injury and delayed evacuation. ⋯ As HBOC-201 restored hemodynamics and tissue oxygenation and decreased fluid requirements, in comparison with HEX, HBOC-201 was at least as efficacious and possibly a superior resuscitative fluid in a military-relevant delayed evacuation hemorrhagic shock swine model.

Practice Guideline
Recommended guidelines for reviewing, reporting, and conducting research on post-resuscitation care: the Utstein style.
The aim of this report is to establish recommendations for reviewing, reporting, and conducting research during the post-resuscitation period in hospital. It defines data that are needed for research and more specialised registries and therefore supplements the recently updated Utstein template for resuscitation registries. The updated Utstein template and the out-of-hospital "Chain of Survival" describe factors of importance for successful resuscitation up until return of spontaneous circulation (ROSC). ⋯ Suggested data are defined as core and supplementary and include the following categories: pre-arrest co-morbidity and functional status, cause of death, patients' quality of life, in-hospital system factors, investigations and treatment, and physiological data at various time points during the first three days after admission. It is hoped that the publication of these recommendations will encourage research into the in-hospital post-resuscitation phase, which we propose should be included in the chain-of-survival as a fifth ring. Following these recommendations should enable better understanding of the impact of different in-hospital treatment strategies on outcome.

In the Austrian emergency medical service (EMS), emergency medical technician-staffed and physician-staffed vehicles are in operation. Patients with suspected acute coronary syndromes (ACS) are treated in the pre-hospital phase and transported to the hospital by an emergency physician (EP). This study evaluates the diagnostic performance of EPs in ACS and the impact of this emergency system on the outcome of ACS in an urban area. ⋯ The percentage of ACS patients transported to hospital by an EP is very low, and EPs seem to be "over-aware" in the diagnosis of ACS.

Factors of importance for the outcome among patients who are admitted to hospital alive after an out-of-hospital cardiac arrest are not well described in the literature. The importance of a history of diabetes for the outcome among these patients has not been reported in detail previously. This survey aims to describe the outcome among patients who were admitted to hospital after an out-of-hospital cardiac arrest in relation to whether they had a history of diabetes. ⋯ Among patients admitted to hospital after an out-of-hospital cardiac arrest, 14% had a history of diabetes. These patients had a lower survival rate compared with those without diabetes, even after correcting for dissimilarities at baseline. It remains to be determined whether an early metabolic intervention in these patients will improve survival.
