Randomized Controlled Trial Comparative Study
Does Dual Operator CPR help minimize interruptions in chest compressions?
Basic Life Support Guidelines 2005 emphasise the importance of reducing interruptions in chest compressions (no-flow duration) yet at the same time stopped recommending Dual Operator CPR. Dual Operator CPR (where one rescuer does ventilations and one chest compressions) could potentially minimize no-flow duration compared to Single Operator CPR. This study aims to determine if Dual Operator CPR reduces no-flow duration compared to Single Operator CPR. ⋯ Dual Operator CPR with a compression to ventilation rate of 30:2 provides marginal improvement in no-flow duration but CPR quality is otherwise equivalent to Single Operator CPR. There seems little advantage to adding teaching on Dual Operator CPR to lay/trained first responder CPR programs.

Randomized Controlled Trial Comparative Study
Comparison of two mechanical intraosseous infusion devices: a pilot, randomized crossover trial.
Administration of medications via the intraosseous (IO) route has proven to be a lifesaving procedure in critically ill or injured children. Two mechanical IO infusion devices have been approved for use in children, the spring-loaded IO infusion device (Bone Injection Gun, BIG) and the battery-powered IO infusion drill (EZ-IO). The objective of this pilot study was to compare the success rates for insertion and the ease-of-use of the two devices. ⋯ As tested by paramedic students on a turkey bone model, the EZ-IO demonstrated higher success rates than the BIG and was the preferred device. Future studies are planned to determine which of the two devices is more appropriate for obtaining IO access in the setting of paediatric emergencies.

Comparative Study
Incidence of iatrogenic dyscarbia during mild therapeutic hypothermia after successful resuscitation from out-of-hospital cardiac arrest.
To investigate the incidence of iatrogenic dyscarbia in survivors of out-of-hospital cardiac arrest treated with induced mild hypothermia. We performed a retrospective cohort study of the ventilatory management based on blood gas analyses of patients resuscitated from prehospital cardiac arrest. In the pilot phase, we assessed the ventilatory management in the patients treated in one university hospital during a 4-year study period. ⋯ The incidence of hypo- or hyper-carbia (dyscarbia) was high (45%). This may predispose for serious derangements in the cerebral perfusion of the resuscitated patient. These results call for vigilance in adjustment of the ventilatory management to meet the needs of the patients treated with mild hypothermia.

Comparative Study
Derivation of a prognostic score for identifying critically ill patients in an emergency department resuscitation room.
Several prognostic scores exist for critically ill patients, including APACHE II, Revised Trauma Score (RTS), Rapid Emergency Medicine Score (REMS) and Modified Early Warning Score (MEWS). However, there is no widely used score specifically designed to predict the likelihood of early intensive care unit (ICU) admission or death in undifferentiated emergency department (ED) resuscitation room patients. We aimed to derive such a score and compare it with other similar scores. ⋯ The Prince of Wales Emergency Department Score (PEDS) is a new prognostic score to predict the likelihood of early ICU admission or death in undifferentiated resuscitation room patients. Further studies are needed to validate and refine this potentially useful tool.

Comparative Study
A national survey of prevalence of cardiopulmonary resuscitation training and knowledge of the emergency number in Ireland.
The aim of this survey was to establish prevalence of cardiopulmonary resuscitation (CPR) training within the last 5 years and reasons preventing training and initiation of CPR in Ireland as well as awareness of the emergency numbers. ⋯ Previous Irish and American population targets for CPR training have been surpassed in Ireland in 2008. New internationally agreed targets are now required. Meanwhile older people and those in lower socio-economic groups should be targeted for training. Awareness of at least one emergency number is very high in Ireland. Some geographical variation was found and this should be studied further.
