Randomized Controlled Trial
Metronome improves compression and ventilation rates during CPR on a manikin in a randomized trial.
We hypothesized that a unique tock and voice metronome could prevent both suboptimal chest compression rates and hyperventilation. ⋯ A unique combination tock and voice prompting metronome was effective at directing correct chest compression and ventilation rates both before and after intubation.

Immediate defibrillation is the traditional approach to resuscitation of cardiac arrest due to ventricular fibrillation or tachycardia (VF/VT). Delaying defibrillation to provide chest compressions may improve survival. We examined the effect of the duration of Emergency Medical Services (EMS) cardiopulmonary resuscitation (CPR) prior to first defibrillation on survival in patients with out-of-hospital VF/VT. ⋯ In this observational analysis of VF/VT arrest, between 46 and 195 s of EMS CPR prior to defibrillation was weakly associated with improved survival compared to < or =45 s. Randomized trials are needed to confirm the optimal duration of EMS CPR prior to defibrillation and to assess the impact of first CPR duration on all initial rhythms.

Emergency Medical Services (EMS) systems play key roles in the rapid identification and treatment of critical illness such as trauma, myocardial infarction and stroke. EMS often provides care for sepsis, a life-threatening sequelae of infection. In this study of Emergency Department patients admitted to the hospital with an infection, we characterized the patients receiving initial care by EMS. ⋯ EMS provides initial care for over one-third of ED infection patients, including the majority of patients with severe sepsis, septic shock, and those who ultimately die. EMS systems may offer important opportunities for advancing sepsis diagnosis and care.

In postcardiac-arrest (PCA) patients, hyperglycemia is a factor reflecting an unfavorable outcome, and might be caused by the inflammation and stress of "sepsis-like" syndrome. In this study, plasma glucagon, a representative glycogenolytic and gluconeogenic hormone, was measured and assessed the correlation for neurological outcome in PCA patients. ⋯ Plasma glucagon reflects unfavorable outcomes in PCA patients, and might be related to ischemic and reperfusion stress.

We investigated the safety, feasibility and efficacy of a resuscitation blanket designed with the intent to protecting the rescuer from the risk of receiving electrical current during defibrillation which, would allow for uninterrupted chest compressions. ⋯ The resuscitation blanket is a safe and useful tool which protects the rescuer from hands-on defibrillation shocks, allowing for uninterrupted chest compressions, and therefore improving defibrillation success.
