Randomized Controlled Trial
A stabilization device to improve the quality of cardiopulmonary resuscitation during ambulance transportation: A randomized crossover trial.
The quality of cardiopulmonary resuscitation (CPR) during ambulance transportation is suboptimal, and therefore measures that can improve the quality are desirable. ⋯ The use of a stabilization device can improve the quality of CPR and posture stability during ambulance transportation, although the effects on the severity of back pain were not significant.

Review Observational Study
An observational study of patient selection criteria for post-cardiac arrest therapeutic hypothermia.
To date, there is no comprehensive assessment of how therapeutic hypothermia and post-arrest care are being implemented clinically. At this stage in the translation of post-arrest science to clinical practice, this analysis is overdue. This study examines the first step of post-arrest care--the selection of patients for TH and post-arrest care. ⋯ This study demonstrates the wide range and variety of patient selection criteria that are being used for implementation of post-cardiac arrest care. The consequences of this selection criteria variability are currently unmeasured and likely underestimated. Variability is likely to breed inefficiency. Some patients who could benefit do not get treated. Other patients get cooled, yet will never regain consciousness. This variability may be important when considering inter-hospital variation in post-arrest care and outcomes.

Return of spontaneous circulation (ROSC) elicits ischaemia/reperfusion injury and myocardial dysfunction. The combination of adenosine and lidocaine (AL, adenocaine) has been shown to (1) inhibit neutrophil inflammatory activation and (2) improve left ventricular function after ischaemia. We hypothesized that resuscitation with adenocaine during early moments of cardiopulmonary resuscitation (CPR) attenuates leucocyte oxidant generation and myocardial dysfunction. ⋯ Infusion of adenocaine during early resuscitation from CA significantly improved early post-resuscitation cardiac function and attenuated leucocyte superoxide anion generation, without a change in post-ROSC neurological function. (IACUC protocol number 023-2009).

Multicenter Study
Association between angiographic culprit lesion and out-of-hospital cardiac arrest in ST-elevation myocardial infarction patients.
Factors related to the occurrence of out-of-hospital cardiac arrest (OHCA) in ST-elevation myocardial infarction (STEMI) are still poorly understood. The current study sought to compare STEMI patients presenting with and without OHCA to identify angiographic factors related to OHCA. ⋯ In the present STEMI population, coronary culprit lesion was associated with the occurrence of OHCA. Moreover, culprit lesion influenced the risk of cardiogenic shock and success of reperfusion, both of which were related to prognosis of OHCA patients.

Cardiac arrest is a common presentation to the emergency care system. The decision to terminate CPR is often challenging to heath care providers. An accurate, early predictor of the outcome of resuscitation is needed. The purpose of this systematic review is to evaluate the prognostic value of ETCO2 during cardiac arrest and to explore whether ETCO2 values could be utilised as a tool to predict the outcome of resuscitation. ⋯ ETCO2 values during CPR do correlate with the likelihood of ROSC and survival and therefore have prognostic value. Although certain ETCO2 cut-off values appears to be a strong predictor of mortality, the utility of ETCO2 cut-off values during CPR to accurately predict the outcome of resuscitation is not fully established. Therefore, ETCO2 values cannot be used as a mortality predictor in isolation.
